kbhit() tells you if a key has been pressed. You can then use getch() to determine the value of the key.

Please specify what you mean by an "object".

can u plz tell how to use kbhit withi getch()

if (kbhit() && getch() == character_you_want) {
    // Yay!
}

object means any character

Well, you can manually keep a copy of the visible screen in memory. I don't think the conio.h library supports extracting already written characters even on Borland compilers. Your next step if you don't want to maintain your own copy of the screen is to use a library such as PDCurses which have the functionality you want (the inch() functions in particular for curses variants).
