    Instantaneous Input

    How do you set it up to actively wait for a key press, and then use that key press. Instead of user typing the letter and hitting enter. I just want them to hit the key. Not have to hit enter as well.

    I tried

    getch()=input;
    switch(input)
    {
    case 'a':
    blah blah
    case 'b':
    blah blah
    }

    but you still have to hit enter after typing the letter.

    Also. how do you do the same thing as above except let them just hit enter to perform a function. I guess i'd need to know the value of the Enter key.

    Thanx ahead of time,
    Darkflame

    char a;
    a=getch(); //in conio.h

    works for some compilers but there is no standard way. What o/s and compiler are you using?

    Try this:

    #include <dos.h>

    char a;

    if(kbhit())
    {
    a = getch();
    cout<<a<<endl;
    }

    For Dev C++ you have to include <conio_mingw.h> if you want to use getch() without have the input echoed on screen.

    In Microsoft Visual C++ you can use:

    Get a character from the console without echo (_getch) or with echo (_getche).

    int _getch( void );

    int _getche( void );

    with <conio.h>.
