The term 'function' is one of several related terms whose definition can shift slightly from one language to the next. In C++, functions can either return a value or not. Do a little research and answer the following two questions. 1. What is meant by the terms cohesion and coupling as they relate to functions? What do we want a function to have? What do we not want it to have? 2. In C++, is there a way for a function to return more than one data item back to the calling program?
