echo command

Write a program to simulate echo command using C/C++?

How to achieve the above?

Thanks in advance

What do you mean by "echo command"?
What functionality exactly?
Should it be able to output system variables values, or just print out given text?
What did you try so far? your question is to broad, you should ask specific questions.

One could easily get the impression that the question above is directly copied and pasted from a school assignment..

Agreed, but I like to play the game, and, maybe he will really learn something by the end of the thread ;)
