5. Difference between int and void return type with main                function

Code : 

#include<stdio.h>

#include<conio.h>

/*Difference between int return type

 and void return type with main function*/

void main()

{

  printf("hello world");

  getch();

}

Void return type have no return value.So this main function gives output without return any value.

Next let's see int main() function...

int main()

{

  printf("hello world");

  getch();

  return 0;

}

Int return integer value so we return any integer value in main function.

Output of both function : hello world
