Question 1 A do-while statement is often used to control a menu-driven program that displays a list of choices from which the program use selects a program operation. For example, the menu displayed for a text editing program might look like this: List of edit operations: D- Delete a substring. F - Find a string. I - Insert a string R- Replace a substring. Q- Quit Enter D, F, I, R, or as your selection: The main control routine for such a program would implement the pseudocode that follows. do Display the menu (call a function: displayMenu(), which displays the above menu) Read the user's choice (by using cin). Perform the user's choice (use a switch statement here. The control variable is a char variable determined from the above cin. If the car variable is 'D', then print out a message: Delete a substring. For other choices, print out the corresponding message. while the choice is not Quit When you run this program, test all the choices of the switch statement
