Before revision: Repetitive code In this second point, it is shown that repetitive code can be found in some macros, which can lead to wasted computing time.The following code illustrates this:Repetitive code of some macros// file example2.c # include <stdio.h>#include <stdlib.h> define max(a,b) (((a) > (b)) ?
After revision: Hiding repeated evaluation # If a macro such as the common function max is defined as define max(a,b) (((a) > (b)) ?
