Too trival to post a solution - Get a character from console (keyboard) and cast it to a signed char (not clever).

It means that you have to learn some C++ before asking questions. Which part of this line is not clear to you?

Please help yourself and do minimum research before asking question.
Your question claim to the word how stupid you are, not even able to perform the most basic research.

Ease up there, mate.

Ok, but when I see this kind of question, sometimes I can't help.

Please see my comment to the question, which is not quite productive.

This is C-style typecast, (char), performed over the value returned by the function _getch(). Depending on the profile of _getch(), it may or make not make sense. The type char is ANSI (non-Unicode) 8-bit character, something which is majorly obsolete. This function, most likely, might be this one, which would require typecast if you need char:

see also: http://stackoverflow.com/questions/814975/getch-is-deprecated[^].

This is all old stuff. One C++ way which would not require this ugly type casting is using cin and cout streams: http://www.cplusplus.com/doc/tutorial/basic_io[^].

I think it has its own ugliness and I remember that one of our high-reputation members claimed he hates it; which I would understand, but typecasting for reading from console is worse.
