Hi Philip,
Well, as I explained in a previous post I know about getchar, and
unfortunately it isn't quite what I am looking for. Besides pausing
the screen I want a function that will act upon a key immediately
rather than waiting for the enter key which getch does and getchar
won't.
However, I have found getchar doesn't always work when pausing the
screen anyway. I have written the following function in C++, and it
fails to do what I want which is to pause until the enter key is
pressed.
void WaitKey()
{
std::cout << "Press enter to continue:\n";
std::getchar();
}
Now, in theory that function should prompt the user to press the enter
key and pause the game until the enter key is pressed. Sometimes it
does and sometimes it doesn't. I have written a test program using
getchar as written above and there are cases where the program ignores
the WaitKey() function I wrote and goes and executes the next function
regardless of my instruction to wait. So I don't think pausing the
screen with getchar is necessarily a valid method for cross-platform
pausing the screen. Of course, there may be a difference between the C
implementation of getchar in stdio.h and the C++ implementation in
cstdio. Not sure if that is a difference or not.
Cheers!
