[C++] Simple Coding Challenges

Dear All,

I am a C++ Beginner and, having read and studied (and sucessfully made
it through the "Hello World" et. al. stage), I wanted to try my hand
at putting it all into practice. To give you an idea of the concepts
that I would like to familiarize myself with: I have just finished
reading N.Josuttis' book "Object Oriented Programming in C++", which
by the way I found a very good read.

My trouble is that any idea and/or challenge I can come up with is
usually too hard, unfocused or requires system-specific code, which is
not what I want to 'train', as it were.

I would hence like to ask you to suggest some places to find some
simple code challenges and/or micro-projects for beginners. To give
you an example, I have found the challenges at
http://www.cprogramming.com/helpfree.html
to be quite enjoyable and helpful.

Any help would be much appreciated,

Yours,
