    Character Literals Character literals are enclosed in single quotes. If the literal begins with L uppercase onlyit is a wide character literal e.

    Otherwise, it is a narrow character literal e. A character literal can be a plain character e. A string contains characters that are similar to character literals: tutorialspoint characters, escape sequences, and universal characters. Here are some examples of string literals.

    All the three forms are identical strings. A modifier is used to alter the meaning of the base type so that it more precisely fits the needs of various situations. In addition, signed and unsigned can be applied to char, and long can be applied to double. The modifiers signed and unsigned can also be used as prefix to long or short modifiers.

    For example, unsigned long int. You can simply use the word unsigned, short, or long, without int. It automatically implies int. For example, the following two statements both downlod unsigned integer variables. Qualifier Meaning const Objects of type const cannot be changed by your program during execution volatile The modifier volatile tells the compiler that a variable's value may be changed in ways not diwnload specified by the program.

    Only C99 adds a new type qualifier called restrict. These specifiers precede the type that they modify. The register Storage Class The register storage class is used to define local variables that should be stored in a register instead of RAM. It should also be noted that defining 'register' does not mean that the variable will be stored in a register.

    It means that it MIGHT be stored in a register depending on hardware download implementation restrictions. Therefore, making pdf variables static allows them to maintain tutorialspoint values between function calls. The static modifier may also be applied to global variables.

    When this is done, it causes that variable's scope to be restricted to the file in which pdf downloar declared. When you use 'extern' the variable download be initialized as all it does is point the variable name at a storage location that has been previously defined. When you have multiple files and you define a global variable or function, which will be used in other files also, then extern will be used in another file to give reference of defined variable or function.

    Just for understanding extern is used to declare a global variable or function in another file. The extern modifier is most commonly used when d are two or more files sharing the same global variables or functions as explained below. First File: main. It allows a member of an object to override const member function.

    That is, a mutable member can be modified by a const member function.

    Called Logical OR Operator. If A B is true. Use to reverses the logical state of its operand. If a condition is true, then Logical NOT operator will make false. Operator Description sizeof sizeof operator returns the size of a variable. X : Y Conditional operator? If Condition is true then it returns value of X otherwise returns value of Y.

    The value of the entire comma expression is the value of the last expression of the comma-separated list. Cast Casting operators convert one data type to another. For example, int 2. This affects how an expression is evaluated. Here, operators with the highest precedence appear at the top of the table, those with the lowest appear at the bottom.

    Within an expression, higher precedence operators will be evaluated first. Check the simple difference with and without parenthesis. In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on.

TutorialsPoint paginaswebcolombia.co Although C# constructs closely follow traditional high-level languages, C and C++ and being an object-oriented programming language. It has strong resemblance with Java, it has numerous strong programming features that make it endearing to a number of programmers worldwide. Following is the list of few important features of C#: Boolean Conditions. C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features. C++ was developed by Bjarne Stroustrup starting in at Bell Labs in Murray Hill, New Jersey, as an enhancement to the C language and originally named C with Classes but later it was renamed C++ in File Size: KB.

    Programming languages provide various control structures that allow for more complicated execution paths. Loop Type Description while loop Repeats a statement or group of statements while a given condition is true. It tests the downooad before executing the loop body. While Loop A while loop statement repeatedly executes a target statement as long as a given condition is true.

    The condition may be any expression, and true is any non-zero value. The loop iterates while the condition is true. When the condition becomes false, program control passes to the line immediately following the loop. When the condition is tested and the result is false, the loop body will be skipped and the first statement after the while loop will be executed.

    The init step is executed first, and only once. This step allows you to declare and initialize any loop control variables. You are not required to put a statement here, as long as a semicolon appears. Next, the condition is evaluated. If it is true, the body of the loop is executed.

    If it is false, the body of the loop does not execute and flow of control jumps donwload the next statement just after the for loop.

    After the body of pdt for loop executes, the flow of control jumps back up to the increment statement. This statement can be left blank, as long as a semicolon appears after the condition. The condition is now evaluated again. If it is true, the loop executes and the process repeats itself body of loop, then increment step, and then again condition.

    After the condition becomes false, the for loop terminates. Syntax The syntax of a do This process repeats until the given condition becomes false. When execution leaves a scope, all automatic objects that were created in that scope are destroyed. Though it is not advised to use goto statement in your program.

    If you are using nested loops i. Instead of forcing termination, however, continue dpf the next iteration of the loop to take place, skipping any code in between. For the for loop, continue causes the conditional test and increment portions of the loop to execute. For the while and do NOTE: Use of goto statement is highly discouraged because it makes difficult to trace the control flow of a program, making the program hard to understand and hard to modify.

    Any program that uses a goto can be tutorialspoiint so that it doesn't need the goto. A labeled statement is any statement that is preceded by an identifier followed by tutorilaspoint colon :. For example, consider the following code fragment: for A simplebreak statement would tutorialspoint work here, because it would only cause the program to exit from the innermost pdf. The Infinite Loop A loop becomes infinite loop if a condition never becomes false.

    The for loop is traditionally used for this purpose. If Download An if statement consists of a boolean expression followed by one or more statements. If boolean expression evaluates to false, then the first set tutorialsponit code after the end of the if statement after the closing curly brace will be executed.

    Syntax The syntax of an if When using if downloaad, else ifelse statements there are few points to keep in mind. Each value is called a case, and the variable being switched on is checked for each case. Each case is followed by the value to download compared to and a colon. If no break appears, the flow of control will fall through to subsequent cases until a break is reached.

    The default case can be used for performing a task when none of the cases is true. No break is needed in the default case. Even if the case constants of the inner and outer switch contain common values, no conflicts will arise. It has the following general form: Exp1? Exp2 : Exp3; Exp1, Exp2, and Exp3 are expressions.

    Notice the use and placement of the colon. If Exp1 is false, then Exp3 is evaluated and its value becomes the value of the expression. You can divide up your code into separate functions. How you divide up your code among different functions is up to you, but logically the division usually is such that each function performs a specific task.

    A function declaration tells the compiler about a function's name, return type, and parameters. A function definition provides the actual body of the function. For example, pdff strcat to concatenate two strings, function memcpy to copy one memory downooad to another location, tutorialsponit many more functions.

    A function is known with various pdf like a method or a sub-routine or tutorialwpoint procedure etc. Some functions perform the desired operations downlad returning a value. The function name and the parameter list tutorialspoint constitute the function signature. When a function is invoked, you pass a value to the parameter.

    This value is referred to as actual parameter or argument. The parameter list refers to the type, order, and number of the parameters of a downnload. Parameters are optional; that is, a function may contain no parameters. Example: Following is the source code for a function called max.

    The actual body of the function can be defined separately. In such case, you should declare tutorialspoint function at the top of the file calling the function. To use a function, you will have to call or invoke that function. When a program calls a function, program control is transferred pff the called function.

    To call a function, pff simply need to pass the required parameters along with function name, and if function returns a value, then you can store returned value. While running final executable, it would produce the following result: Max value is : Function Arguments If a function is to use arguments, it must declare variables that download the values of the arguments.

    These variables are called the formal parameters of the function. The formal parameters behave like other local variables inside the function and are created upon entry into the function and destroyed upon exit. While calling a function, there are two ways that arguments can be passed to a function: Call Type Description Call by value This method copies the actual value of an argument into the formal parameter of the function.

    Pdv this case, changes made to the parameter inside the function have no effect on the argument. Call by pointer This method copies the address of an argument into the formal parameter. Inside the function, the address is used to access the actual pdf used in the call.

    This means that changes made to the parameter affect the argument. Call by reference This method copies the reference of an argument into the formal parameter. Call by Value The call by value method of passing arguments to a function copies the actual value pdf an argument into the formal parameter of the function. In general, this means that code within a function cannot alter the arguments used to call the function.

    Consider the function swap definition as follows. Call by Pointer The call by pointer method of passing arguments to a function copies the address of an argument into the formal parameter. This means that changes made to the parameter affect the download argument.

    To pass the value by pointer, argument pointers are passed to the functions just like any other value. So accordingly you need to declare the function parameters as pointer types as in the following function swapwhich exchanges tutorialspoint values of the two integer variables pointed to by its arguments.

    In tutorualspoint, this means that code within a function cannot alter the arguments used to call the function and above mentioned example tutirialspoint calling max function used the same method.

    Default Values for Parameters When you define a function, you can specify a default value for each of the last parameters. This value will be used if the corresponding argument is left blank when calling to the function. If a value for that parameter is not passed when the function is called, the default given value is used, but if a value is specified, this default value is ignored and the passed value is used instead.

    These are functions that can be included in your program and then use.

    There are actually two functions you will need to know about random number generation. The first is randthis function will only return a pseudo random number. The pdf to fix this is to first call the srand function. Following is a simple example to generate few random numbers. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

    Instead of declaring individual variables, such as number0, number1, A specific element in an array is accessed by an index. All arrays consist of contiguous memory locations. The lowest address corresponds tutorialwpoint the first element and the highest address to the last element. Following is an example to assign pdf single element of the array: If you omit the size of the array, an array just big enough to hold the initialization is created.

    Array with 4th index will be 5th, i. Following is the pictorial representation of rownload same array we discussed above: Accessing Array Elements An element is accessed by indexing the array name. This is done by placing download index of tutorialspoint element within square brackets after the name of the array. Following is an example, which will use all the above- mentioned three concepts viz.

    The simplest form of the multidimensional array is the tutorialspoint array. Pointer to an array You can generate a pointer to the first element of an array by simply specifying the array name, without any index. Here tutorialspolnt the general form of a multidimensional array declaration: type name[size1][size2] A two-dimensional array is, in essence, a list of one-dimensional arrays.

    A two-dimensional array can be think as a table, which will have x number of rows and y pdf of columns. A 2-dimensional array a, which contains three rows and four columns can be shown as below: Thus, every element in array a is identified by an element name of the form a[ pdf ][ j ], where a is the name of download array, and i and j are the subscripts that uniquely identify each element in a.

    Following is an array with 3 rows and each row have 4 columns. You can verify it in the above digram. However, You can pass a pointer to an array by specifying the array's name without an index. If you want to pass a single-dimension array as an argument in a function, you would have to declare function formal parameter in one of following three ways and all three declaration methods produce similar results tutoeialspoint each tells the compiler that an integer pointer is ddownload to be received.

    However, you can return a pointer to an array by download the array's name without an index. Thus a null-terminated string contains the characters that comprise the string followed by a null. The following declaration and initialization create a string consisting of the word "Hello".

    To hold the null character at the end of the array, the tuyorialspoint of the character array containing the string is one more than the number of characters in the word "Hello. A pointer tutorilspoint a variable whose value is the address of another variable. Like any variable or constant, you must declare a pointer before you can work with it.

    The asterisk you used tutorialspoint declare a pointer is the same asterisk that you use for multiplication. However, in this statement the asterisk is being used to designate a variable as a pointer. The only difference between pointers of different data types is the data type of the variable or constant that the pointer points to.

    Passing pointers to functions Passing an argument by reference or by address both enable the passed argument to be changed download the calling function by the called function. Null Pointers It is always a good practice to assign the pointer NULL to a pointer variable in case you do not have exact address to be assigned.

    This is done at the time of variable declaration. A pointer that is assigned NULL is called a null pointer. The NULL tutorialspoint is a constant with a value of zero defined in several standard libraries, including iostream. However, the memory address 0 has special significance; it signals that the pointer is not intended to point to an accessible memory location.

    Many times, uninitialized variables hold some junk values and it becomes difficult to debug the program. Pointer Arithmetic As you understood pointer is an address which is download numeric value; therefore, you can perform arithmetic operations on a pointer just as you can a numeric value.

    This operation will move the pointer to next memory location without impacting actual value at the memory location. If ptr points to a character whose address isthen above operation will pdf to the location because next character will be available at Incrementing a Pd We prefer using a pointer in our program instead of an array because the variable pointer pfd be incremented, unlike the array name which cannot be incremented because it is a constant pointer.

    If p1 and p2 point to variables that are related to each other, such as elements of the same array, then p1 and p2 can be meaningfully compared. In fact, pointers and arrays are interchangeable in many cases. For example, a pointer that points to the beginning downlosd an array can access that array by using either pointer arithmetic or array-style indexing.

    The reason for this is that var is a constant that points to the beginning of an array and can not be used as l-value. Because an array name generates a pointer constant, it can still be used in pointer-style expressions, as long as it is not tutorialspoint. Thus, each element in ptr, now holds a pointer to an int value.

    Normally, a pointer contains the address of a variable.

    When we define tutorialspoint pointer to a pointer, the first pointer pdf the address of the second pointer, which points to the location that contains the actual value as shown below. A variable that is a pointer to a pointer tutorialspoimt be declared as such. This is done by placing an additional asterisk in front of its name.

    To do so, download declare the function parameter as a pointer tutorialsppint. Now, consider the following function, which will generate 10 random numbers and return them using an array name which represents a pointer i. Once a reference is initialized with a variable, either the variable name or the reference name may be used to refer to the variable.

    You must always be able to assume that a reference is connected to a legitimate piece of storage. Pointers can be pointed to another object at any time. Pointers can be initialized at any time. You can then think of a reference as a second label attached to that memory location. Tutorialspoibt, you can access the contents of the variable through either the original variable name or the reference.

    Thus, read the first declaration as "r is an integer reference initialized to i" and read the second declaration as "s is a double doanload initialized to d. References as Parameters We have discussed how we implement call by reference concept using pointers. When a function returns tutodialspoint reference, it returns an implicit pointer to its return value.

    This way, a function can be used on the left side of an assignment statement.

    So it is not legal to return a reference to local var. But you can always return a reference on a static variable. If the system has no time. C is a general-purpose, procedural, imperative computer programming language developed in by Dennis M. C is the most widely used computer language.

    It keeps fluctuating at number one scale of popularity along with Java programming language, which is also equally popular and most widely used among modern software programmers. All tuyorialspoint content and graphics published in this e-book are the property of Tutorials Point I Pvt.
