At the risk of boring everyone:
There are a couple of reasons that we have to type "int main( ... )". The
biggest one is that way back in the early days of C there were no qualifiers on
functions, so it was just "main( ... )". The int was implied, and you could
not say "unsigned char main".
There were no prototypes and no declarations in the arguments, so main looked
like this:
main( argc, argv )
char *argv[];
{
/* Some code. */
}
Note that argc is implied to be int.

Bummer. Why do we write 'int main( )' then rather than 'char main( )' ?
