How do I make it so std::string TheArray = LegendArray[SelectedLegend1]; works? I'm trying to make it cout the output of the randomized array as shown below.

Why isn't it working? What does your compiler tell you?

'LegendArray' : undeclared identifier

Several things, first srand() should only be called once, usually in main().

Second SelectedLegend1 is local to each of those if() statements. If you want it available outside the if() statement you need to create the instance before the if() statements and then assign a value to that value inside those if() statements.

What is with all of those returns?

Do you realize that "TheArray" is only created if the final else statement executes.

EDIT: You also should do some research on variable scoping in C++.
