Lecture 8: Introduction to Value Returning Functions

In this lecture, we introduce the notion of value returning functions in C++ and provide several examples. Value returing functions are quite similar to functions you would, say, see in excel. However, there are some important differences that we will notice between the two later in the course, particularly in respect to parameter passing modes. We cover both using pre-definied functions and creating programmer-defined functions. Lastly, we finish with a brief introduction to separate compilation.
