Write a c++ program for the following

The colors red, blue, and yellow are known as the primary colors because they cannot be made by
mixing other colors. When you mix two primary colors, you get a secondary color, as shown here:
 When you mix red and blue, you get purple.
 When you mix red and yellow, you get orange.
 When you mix blue and yellow, you get green.
Design a program that prompts the user to enter the first letter of names of two primary colors
to mix. If the user enters anything other than “r,” “b,” or “y,” the program
should display an error message. Otherwise, the program should display the
name of the secondary color that results. Implement it using if\else structure and then switch structure.

use switch structure and if/else
