First and foremost - don't use "goto" in C++. Ever. It's problematic, often dangerous, and there is almost always a much better way of structuring your code. There are rare circumstances in which it's appropriate to use "goto", but unless you're experienced enough to understand exactly why it's a dangerous thing to do - and clearly you're not - then you shouldn't use it.
Learn how to use the basic control structures that C++ provides:
Definitely listen to MikeyBoy's post. He raises some very important points. The only thing to add is to suggest using functions and classes to make this game, which will make the task (at least) 10x easier. I'd definitely recommend learning about all this and then starting an RPG, as opposed to struggling through a badly designed RPG and then learning everything that would have made it easier afterwards.
^^ What he said. Until you learn basic functions and control structures a text based RPG is just going to waste your time and instill bad habits. Wait until you learn some OOP (Object Oriented) and then you can do it right.
