First of all, what error does the compiler return?

I think the problem is the fact that you declare the variable seatingArray locally in your display_array function. Your other functions seem to use the variable, but they don't have access to it. Declaring the variable globally should solve that problem.

Your last function seems to have a few syntax errors too. First of all I'd remove the "do" in the theater_full function. And then add another closing bracket at the end of the function.

A third problem I noticed just now is how you're reading from cin in your display_array function. You're reading from cin and storing the value in a function parameter, but since it's passed by value the read value is not stored in the variable you passed, but in a copy of it, which will be destroyed at the end of the function. You can solve this by passing the variable by reference. The new function definition would then become void display_array (int& userRow)
