Creating Program-Defined Value-Returning Functions
As mentioned earlier, you can create your own functions in C++. The functions you create
are referred to as program-defined functions because their definitions are typically contained

program-defined value-returning function: main.
Figure 9-12 shows the syntax for creating (or defining) a value-returning function in a C++
