Variadic Example #3

/*  Here's one more example on using variadic functions that I was playing with.  This on scans an entered string and looks for '!', reporting if it's found with "DETECTED", then applies a few different treatments to the string depending on what int parameters are sent down.  Mostly I did this to see if I could, with the idea being: could it be possible to pseudo-replicate what happens with a "printf" function?
