[C++] Improve Nested Switch() Statement

closed account (G30oGNh0)
Hey guys just a quick one.

I am writing a program that prompts the user for a key and a scale which returns the scale structure for the musical key.

I'd like to know of any other way of doing this seemingly big switch statement?

Thanks in advance and please document code whenever necessary.
