Re: Nov 15 - Day 4: Additional Approaches to Support Code Reusability

@JCarlson: why not printf (a)?? Printf is a variable-argument function. You can have with one parameter, printf("hello"), and you can have it with four parameters, printf("combo %d, %d, %d", a, b, c), and so on. But CPP macros do not support variable argment lists. So,

#define PRT_DEBUG(a) printf a

makes it so that PRT_DEBUG(("hello")) and PRT_DEBUG(("combo %d, %d, %d", a, b, c)) has only one parameter, a, in both cases.
