Because 'status' is integral, you can also
use a switch statement:
switch ( status )
{
case GLP_OPT:
case GLP_FEAS:
...
break;
case GLP_INFEAS:
...
break;
default:
...
break;
}
Don't forget the break statements!
If you want robust code, I would throw an C++ exception
rather than use a goto -- but then I come from the
generation that was taught that gotos were poor style.
