Hello all:
I am trying to make my change maker calculate the correct amount of change given and its not calculating at all. My program is compiling and running but I cannot seem to find the issue with my algorithm. Can anyone provide some feed back as to what I'm doing wrong and point me in the right direction?
I know it's a mess but can some please help me make this work?Code:#include <stdio.h>
#include <math.h>
