First, the escolha variable is not declared in this code.

But the big problem is that you used || instead of && . Look at this:

escolha!=1||escolha!=2

Consider, if escolha is 1, we have it is different from 2, so it remains in do-while . If it is 2, then it is different from 1 and also continues.

What you wanted was this:

escolha != 1 && escolha != 2
