Hi all,
How to implement automatic completion i.e, suppose
Assume that there are commands like

show
show version

As soon as you press "s" and tab it should display "show ".

Please any one help..

First of all, you'll need to detect when the TAB key which means you'll have to capture individual keyboard key presses. This is implementation-dependent. In Windows, use kbhit() or (for VC++) _kbhit(). In Linux, check out the ncurses library.
The way I see it, you'll have to make a loop which handles alphanumeric key presses by displaying them on the screen and storing them in a buffer (like the normal line input functions of C++ do), and detects TAB key presses, responding accordingly by completing the word on the screen and in the buffer. The loop should also detect when the Enter/Return key is pressed then exit.

Hey,
check out the bioskey(),first note the values for each key press and proceed

The bioskey() function is largely obsolete, it only works in older versions of Borland's Turbo C I think.
