Hi hope this is the correct thread.

Created an application for the changing a pattern given a pattern AAAA and a char B
Will end up with BBBB following making one change at a time i.e AAAB AABA AABB ABAA.

It works but I guess there is a faster or a recursive way of doing it.

Anyway just review this. This is not for college or unie. As we move more and more towards framwork I want to try and keep my basic coding skills as sharp as I can.




Main application


The object container

isn't this really just counting in binary? let 0 = A and 1 = B.

0000
0001
0010
0011
0100
0101
0110
0111
etc

you could just count from 0 to 15, use a mask to check each bit, and print the associated character.
