Use C++ to successfully complete this criterion. Your simple program will need a menu that can validate user input and is easy to use. It needs to include options for the display of a multiplication table, doubling a value, and exiting the program. If either of the first two options are selected, then users need to be prompted to input a numeric value. The menu should be displayed using a loop, where the user can choose to exit the program only by selecting option 3. Any user input other than 1, 2, or 3 should result in an error message that returns the user to the menu.

Design a menu with appropriate user interactions and checks for valid entry. Use C++ to successfully complete this criterion.

An example menu might look like the following:1: Display a Multiplication Table 2: Double a Value 3: Exit Enter your selection as a number 1, 2, or 3.

Create code that prints a multiplication table for a given numeric value. Both C++ and Python will be necessary to successfully complete this criteria. Be sure to focus on their interactions as you work. Consider the following steps to help organize your code design.
