 | Your code is extremely hard to read due to the seeming random indentation. If you indent consistently, it's easy for you and us to read. Visual Studio Express will format code properly with a few keystrokes. It's almost impossible to tell where a loop or an if statement starts and … |
| | Lines 36 - 40 aren't function calls. Looks like they are function declarations, so they should be above main where your other function declarations are (lines 7 - 12). Move them up there and if you get any duplicates for a function, delete one of them. A function CALL would … |

| | For this much code to wade through, that's too vague of a question, in my opinion. What exactly is the problem? What should the code do? What does the code actually do? What does it do that it shouldn't, what does it not do that it should? Under what circumstances? … |
