In this exercise, you will create a program that displays a measurement in either inches or centimeters. If necessary, create a new project named Introductory18 Project, and save it in the Cpp8\Chap09 folder. The program should allow the user the choice of converting a measurement from inches to centimeters or vice versa. Use two program-defined functions: one for each different conversion type. Enter your C++ instructions into a source file named Introductory18.cpp. Also enter appropriate comments and any additional instructions required by the compiler. Test the application appropriately.
