FUNCTIONS IN C PROGRAM

In any programming language the ability of the language to reuse a peice of code  is vital and in C programming function provide us to way to do repetetive task easily, now i write a simple function that weil demonstrate the use of functions

#include<stdio.h>

int main()
{
 
        hello();     //calling a function

  }


   void hello()                  //defining a function header
{

     printf("hello world");       //function body

}
   

In above program we have written a very small function which allow us to print words hello world on the screen , the word void before the function name indicates the return value of function which in this case is none , every function returns a result which can be either integer, char, float or double or none is good practice to prefix function name with its return type
