The variables declared so far have been of different types with different sizes and capabilities. Even so, each variable has been capable of holding only a single value at a time. If I wanted to hold three numbers, I had to declare three different variables. The problem is that there are times when I want to hold a set of numbers that are somehow closely related. Storing them in variables with names that bear some similarity of spelling such as nArg1, nArg2, and so on may create associations in my mind but not for poor, ignorant C++.
