I am not going to look at a 230 unindented line C program, especially when it contains such helpful variable names like "c" and "m". What's broken? What should it do, and what is it doing? How To Ask Questions The Smart Way

This is not how a real working program functions. The first category is mostly informational. The data is not stored in a database where the items and prices can be easily updated.
