Is it a good idea to eliminate compiler warnings?

Question

In the past I\'ve worked with -Wall and other switches for gcc to eliminate every compiler warning for projects I\'ve been involved in. Similarly, in Perl, I always program wit

Answer 1

There are two compliant prototypes for main in C.

int main(void)

and

int main(int argc, char **argv)

void main(void) is not technically correct, although it may be supported by some compilers as an extension to the standard.

So, in your particular case, you can use a short declaration of main and, if compliant, it won't trigger the warning.
