Write a complete program c++ that asks the user to enter one of two options: 1. The letter C for calculation. 2. The letter T for test. If the user inputs the letter C, the program must read an expression from the user and must display the result of the calculation on the screen. If the user inputs the letter T, the program must read an expression and its result from the user. In this case, the program displays TRUE if the result of the equation is correct and displays FALSE otherwise. The program must work on the mathematical operations: +,-, *,/. You must use the (switch statement) for the different mathematical operations. 3:59
