it will display

How to implement this in C.

That is a function of the operating system not the program, and therefore not the C/C++ code.

As far as I am aware Linux and Windows do this, other OS's may to.

Hi,
I know it OS dependent... But in my project , I should do the implementation of it..
I am asking whether any in-built method is there to do that completion..

No. There is no method that equates to a program that can do auto command completion.

GNU (in linux) has a library that performs command line history and autocompletion. This library can be called from C programs.

Take a look at http://tiswww.case.edu/php/chet/readline/rltop.html for more info.

One way to implement this would be to capture keystrokes (without printing them), compile a list of all executable files in your $PATH directories, and apply regular expressions (or simple string comparison) to that list with the string that has been entered already.
