Find online (perferably in github) interesting C++ code exhibiting an unusual/clever use of control flow structures discussion in the chapters for this week, or exhibiting interesting use of functions. Post a 5-10 line code snippet plus github link for the snippet. Discuss what the code does and why the control flow/function use is interesting. Is the code easy to read? Did you find it easy to figure out what it did? What made it hard or easy?
