Programming Challenge (for my school)

Hello, I'm new here, I recently learned basic C++ programming and I've been tasked to make a programming challenge for our school activity. I heard from our instructor in my previous school about a program (I can't remember if it was in C++) which displays it's whole code without reading another file (like a text document which has the code). Can this be done with just basic knowledge of C++? If so can you please tell me how to do this? Or if this is an advanced programming problem perhaps you can sugest another challenge which doesn't need advanced programming knowledge. :)

You mean its actual source code??
if so just read in char by char with cin.get(ch); and open the file as
ifstream fin(__FILE__);

> which displays it's whole code without reading another file
Yes, they're called quines (you can google that yourself). Coming up with an original one is quite hard to do.

Conway's game of life - you can google that as well.
