Saving Code

MikeTheFish (18)
I've made a quiz template to help me review my school material. It's fairly easy to make a new exe by just changing the couts and one variable. However, it would be a lot easier to be able to be able to have it say something like: "What is your first question?" and you be able to put the question in, saving it as a string like "questionOne," and reopening a file with that questionOne, as well as other questions, possible choices, and the correct answer, saved. I know this is possible, but I've looked at writing and reading to files but it doesn't really work too well for me. Any ideas? Here's the code for it:
