    }
    sometimes

    Code:

    {
      printf( "Welcome to C Programming.\n" );
    }
    sometimes
    Code:
     int main()

    Because example code isn't perfect.

    Whenever you see any of the other three example types, convert it to the third form. Even safer would be to convert it to:
    Code:
    int main(void)
    {
        /* ... */
        return 0;
    }

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    The main should always return an integer, this is what the C/C++ standard says. void main is not correct in this sense.
