Entry point to C programs

int main(void)
{
    // Instructions
}

The braces wrap all code that comprises the program.

The return type is int. It receives no arguments so the arguments are void.

Why does it return an `int`?

It returns an int because the main function returns a success code: 0 for success and 1 for error.

As C was divised to create Unix, this fits in with other Unix-like OS behaviour such as bash scripts returning 0/1.
