C++ Assignment: Write a simple re-occurring program where the user selects 1 of 19 functions() from geometric math formulas (see attached file) from a switch statement (displayed as a list) in your main(). Once the user selects a function(), it asks the user for a value(s) and performs the calculation of the selected function(). If user enters 20; it ends the code. The list of formulas are listed below.
