Structure of  C Programming Language

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

•          Comment Line
•             Header file declaration
•             Main function
•           Opening barse
•           Body of program   
•      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>      

stdio is standard for input/output, this allows us to use some commands which includes a file called stdio.h. Or This is a preprocessor command. That notifies the compiler to include the header file stdio.h in the program before compiling the source-code.

     ·       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.

       ·       printf()      

It is a function in C, which prints text on the screen. OrThis is another pre-defined function of C which is used to be displayed text string in the screen.

Example:

/* write a program to print hello */

#include<stdio.h>

#include<conio.h>

Void main()

{

printf(“hello sir welcome to today class of c”);

getch();

}

Output:

Hello sir welcome to today class of c
