First off, your code is already reading(cin) and writing(cout).

Also you're getting into bad habits using goto. I have yet to see any code where using the goto structure is absolutely necessary. I would suggest following some tutorials on OOP(Object Oriented Programming).

Once you get your code cleaned up to the point where someone else will be able to understand your code, then you can look at adding functionality to it.

Since this is an English speaking site. I would suggest translating your menus. It's very difficult to try and figure them out.

commented: can you change it please i want to learn +0
