You could have the text saved to different files and determine which one to load based on what language the user chooses if that makes and sense. Lazy Example:
but how will I perform different operations if i use a text file.
I basically want to replace the output questions or statements displayed on the screen to be in different language depending on what d user chooses without affecting the operations performed by the program
I read a tutorial online a while back that said you could use the system() function to do that, but you're better off just getting a graphics library. You'll need a graphics or gaming library anyways to get a game going in C++ that isn't text-only.
