Error in compiling hello world in c

I am a beginner in learning c although I took two java courses at school. I just started learning c with "The C Programming" book.

I am trying to compile my first program, "hello.c"

I typed in as the book says:

#include <stdio.h>

main()
{
    printf("hello, world\n");
}

However, it says that I have to write the type specifier 'int' before main(). I'm trying to understand why this is so because the book dosen't indicate about the type specifier.

Thank you!

Your main function needs to return something, that's what the compiler is telling you.

#include <stdio.h>
#include <stdlib.h>

int main() {
    printf("hello, world\n");
    return EXIT_SUCCESS;
}

EXIT_SUCCESS is defined in stdlib. It means that the application successfully ended. Its value is usually 0.
