    getch() equivalent in C++

    I'm not quite good with C++'s standard library, I need help. Is there a function which will behave like getch() (yes, I know it's not C's standard either), that is, return after exactly one character typed into the standard input stream? I tried cin.get(char&) and int cin.get() but it didn't work. I searched, too, but it proved useless.

    There is no standard way defined. You have to use non-standard extensions, which would depend on what OS/Compiler/Run-Time Library you are using how you achieve that. I expect that there isn't a way to (trivially) do that with cin - you'd have to use system specific code (such as include <conio.h> and use getch() if that exists in your implementation).

    As matsp said, there is nothing in the standard library to help you, but you can call getch() in C++ just as easily as you can in C.
