Structure of  C++ Program

Structure of c program will explain the step of c program in how many step a program will developed so there are the step:-

1.    Comment Line

2.    Header file declaration

3.    Main function

4.    Opening barse

5.    Body of program

6.    Closing barse

 

·       /* Comments */

Comments are a way of explaining what makes a program. The compiler ignores comments and used by others to understand the code.

·       #include<stdio.h>      

     #include is a specific preprocessor command that effectively copies and pastes  the entire text of the file, specified between the angle brackets, into the source code.

  The file  iostream which is a standard file that should come with the C++   compiler, is short for input-output streams. This command contains code for displaying and getting an input from the user.

iostream file defines two names used in this program - cout and endl.

 

·       int/void main()  

int/void is a return value, which will be explained in a while.

·       main()       

The main() is the main function where program execution begins. Every C program must contain only one main function. Or This is the main function, which is the default entry point for every C program and the void in front of it indicates that it does not return a value.

 

 

·       Braces                                                

Two curly brackets "{...}" are used to group all statements. Or Curly braces which shows how much the main() function has its scope.

·       Cout<<     

    The name cout  is short for character output and displays whatever is between the << brackets.

Symbols such as << can also behave like functions and are used with the keyword cout.

   

Example:

/* write a program to print hello */

#include<iostream.h>

#include<conio.h>

void main()

{

Cout<<“hello sir welcome to today class of c”;

getch();

}

Output:

Hello sir welcome to today class of c
