What is the use of “void main()”?

Question

Whenever I compile using “void main” as my entry point the output always error. Why like that?
Should I use int main?

Answer 1

provide your code

Answer 2

#include <stdio.h>
void main()
{
int x = 5;
if (true);
printf(“hello”);
}

Answer 3

you’re right. I try it many times but the output errors. So I try int main and it run.

Answer 4

main() is a function called by OS, and it should return an int to tell status.

return 0; // successful

if returned something else then OS will know something went wrong with the code.
return - 1, 1, 2, - 2 //:-(

I know this that void main() doesnt return anything, so doesnt mean anything for OS, maybe compiler adds it.

I only remember void main () in text book codes to save 1 line from return statement.
