I suggest running your app in a debugger. That way, you'll be able to see what's going on, which lines of code are being executed, and what values are being calculated.

I am using Visual Basic and debugging it, but I don't know where to look to see what you are talking about.

MikeyBoy (5631)

I assume you mean Visual Studio?

A quick Google search for "c++ debugging tutorial" should provide some useful links to get you started.

@aflangdon

Just some style points.

First is your variable names - one could directly interpret not_for_toddlers as meaning "Not for toddlers", rather than "Number of tickets for toddlers".

You have a lot of repetition in your code. Lines 102 -119 & 122 - 134 for example is repeated 4 times which is 126 LOC.

So these should be in functions.

In general switch cases should call functions if they are more than a small amount of code.

There is a bit of an unwritten rule that a function (including main) should not be more than 80 LOC - some even go for 20 - 40 LOC.

Check out the assignment operators += and -= and *=, plus others. They can be used like this, for example:

Gross_total += price;

These operators are good because they save on typos and shorten up the code a bit.

Hope this helps.
