Learn Finance C++, Lesson 3, Inputting variables into the program for flexibility

If 'cout' is a black hole, which sucks matter out of the universe of the program and sends it somewhere else, such as a monitor, 'cin' is a white hole, which pushes matter into the universe of the program, from an outside source (such as a keyboard). The 'cin' function adds enormous flexibility to any C++ program, and will help us work with varying loan amounts, varying interest rates, and varying loan periods, in our 'Amortization Engine' that we are building towards.
