CLI

Combine the two problems Number Calculator and Shape Area Calculator into a single application. Create a menu for the user to select the calculator type. Also provides error checking for inputted values. The application should accept correct values with leading and trailing blank characters example, two\t is still equal to two. If the user makes three consecutive errors at any point, exit the application with a non-zero status code. Use functions and while loops for error checking and repeating input prompts.

In the main menu, shape is the command the user will type to access the space calculator. calc is the command the user will type to access the word calculator. quit is the command the user will type to exit the program.

The quit command will exit the program with a 0 status code.

Submit the source code function in a file named functions_calculator.cpp
