getch() in c++

[Vijayan]

Hi...
I want to get the input from the user, without making him to press 'ENTER' key. I could achieve this in c language, by using getch() function. But, this doesn't hold good for c++.
Please help me...

You need to use some third party library for this as pd|n curses
Notice that if you don't really need this is more a pain than useful

And this is because input is sent to the program (your program) from the operating system, which by default (linux/windows) is set to only forward said input on recieving the '\n' character at the shell/command line level.

Doing what you want to do is possible, but requires telling the OS to change its behavior a bit.

:o Thank you very much... Could you give me a small snippet with curses library.?

Here is a hello world example: http://tldp.org/HOWTO/NCURSES-Programming-HOWTO/helloworld.html

And here another example:

#include <curses.h>

int main()
{
    initscr();
    char c;
    printw ( "enter any character besides 'q':\n" );
    do
    {
        c = getch();
        printw ( "\nYou entered %c \n", c );
        refresh();
    }
    while ( c != 'q' );

    endwin();
    return 0;
}
