Having some trouble finshing up a C project. From the looks of it I believe my shopping chart is not updateing correctly.

If I could have some help with this I would appericate it.

My error

How output should look

Code follows below.

ItemToPurchase.c

#include "ItemToPurchase.h" #include #include
