Is there any predefined function

[Ralph]

Is there any predefined function or command available in C programming language for detecting key press of a user? I am using windows XP operating system.

There are various ways of getting the value of key pressed and then detecting the key presses. One way is to use getchar() function in C program which returns the ASCII value of the key pressed.

I think you can also make use of getch() function to get your results. Someone kindly update me on this.

I think shift key has problem using getchar() but for shift key you can use getch().Someone correct me if I am wrong. Also I think there may be some keys which do not have associated ASCII equivalents.

Yes you right there may be some keys which do not have associated ASCII equivalents. For handling such instances make use of virtual key codes to detect the key pressed.
