What's the C++ Equivalent to _getch()?

Question:
What is the C++ equivalent to _getch()? I need to have program control immediately after any keypress in a DOS-based program.

Answer:
Unfortunately there is no specification in the C++ language or libraries that imposes any kind of restriction on buffered/unbuffered input/output. This is so because there are so many platforms on which C++ is supposed to work and it would be impossiable for all of them to support such operating system-specific features.

Your best bet in these cases is to use what ever is available in your OS. In your case, if _getch() works, use it.
