Hi do you think it''s bossible to have one array wich holds same return type funcs but difrend parameter list? And you could use it shometing like this: farray[SPRINTF]("printing using func array\n"); // or what ever

const int MAX_FUNCTION= 300;
void (fnPointer*)(...);
fnPointer farray[MAX_FUNCTION];

switch(code) {
case SPRINTF:
    farray[SPRINTF]("printing using func array\n");
    break;
case OTHER:
    farray[OTHER](std::ostream(os));
    break;
case SOMETHING_OTHER:
    farray[SOMETHING_OTHER](true);
    break;
case ANOTHER_OTHER:
    farray[ANOTHER_OTHER](std::complex(1, 0));
    break;
case LAST_OTHER:
    farray[LAST_OTHER](std::complex(1, 0), std::complex(9.0, 14));
    break;
default:
    farray[DEFAULT]("default called",false);
}
etc.

If I saw you do this I''d have to sack you.

Cool! I totally forget "..." operator, thanks AP.
