Answer 1

Depending on your need and platform, you may use getch() (or _getch()), or ultimately getchar().

The problem with getchar() is that it requires the user to press "enter". The advantage with getchar() is that it is standard and cross-platform.

getch() get all the other property : it just needs a key to be pressed, no display, no "enter" needed. But it's non standard, so support varies depending on platform.

Alternatively, for windows only, there is also :

system("pause");
