For my project, i have to be able to monitor the keyboard for input. Rather than having the user type in 'r' then hitting enter for an action, how would i have the user type 'r' and then have the action perform, skipping the process of hitting enter.
There are no standard C or C++ functions that will do what you want. Bu8t there are some non-standard functions in conio.h, if that has been implemented by your compiler. You could also probably use something like ncurses library, or other win32 api functions.
