More like an interpreter. An interpreter executes the "translated" program as it is converting it (as does your system). A compiler transforms the original into something else that you can store and then run at a later date once the "translation" is complete.

A couple of optimisations of your code, BTW. You can't do "n--" if n is a floating point number. Also, this assumes that the value of n has been checked for validity and that it is in fact a positive integer value (expressed as a floating point).

Code:

int main(void) {
 double product = 1.0;
 unsigned int n = (unsigned int)level1;
 for(; n > 1;) product *= n--;
}
