Got a small question 😁(Difference)?

Question

Here is a code of C...

#include <stdio.h>

/* A simple C program
* Version 1.0
*/
int main() {
/* Output a string */
printf("Hello World!");
return 0;
}

What is the reason for including return 0 on it👆,and this same code also works fine without the return 0 also works....so what is the purpose of including return 0...

Answer 2

A successful program returns a 0, non-zero value means failure.
Yp you can run the main function without the return 0. It works the fine. But it's a good practice to follow.
