{than do this}

i know i use and if and i need to do something like the ketkey were if the user presses a key than the program will do some stuff

I think you might want to look into Windows programming to do that, using the Windows procedure to peek for a message from the keyboard.

In just standard C++ for console apps, you can't do this...unless you're waiting for the user to press the ENTER key.

I think this could help you

that helps alot

If your working with a Windows console this might be of some use. In combination with Virtual-Key Codes I think you could figure it out.

#include <windows.h>
#include <iostream>
#include <cstdlib>

using namespace std;

WORD scanKeyboard(void) 
{
        DWORD dwCharsRead;
        INPUT_RECORD inRec;
        HANDLE hInput = GetStdHandle(STD_INPUT_HANDLE);
       
        while(ReadConsoleInput(hInput, &inRec, 1, &dwCharsRead)) 
                if(inRec.EventType == KEY_EVENT && inRec.Event.KeyEvent.bKeyDown)
                        return(inRec.Event.KeyEvent.wVirtualKeyCode);
                       
        return('ì'); // dummy return to suppress warning msg.
}


int main( int argc, char * argv[] )
{       
        WORD c;
       
        do
        {     
          cout << "\nEnter something, N to exit: ";
          c = scanKeyboard( );
          cout << c;
          if(c == VK_UP)
                cout << " : Up Arrow key pressed";
        }while(c !='N');

        return(0);
}
