Question
Mathtotor2.cpp (20 pts)
Write a program that can be used as a math totor for a young student. The program should display a menu allowing the user to select one of the four options: 1) Addition, 2) Subtraction, 3) Multiplication or 4) Quit. The program then displays two random numbers between 10 and 50 that will be calculated. After the user has finished the math problem, the program should display the menu again. This process must repeat until the user chooses to quit the program. If the user selects and item not on the menu, the program should print an error message and then display the menu again.
Guidelines:
Need the following preprocessors:
#include <iostream>
#include <iomanip>
#include <cstdlib>
#include <ctime>
#include <string>
Do
{
Display menu and collect choice;
switch statement
{
Case 1
Case 2
Case 3
Case 4
}
If choice is 1 or 2 or 3
Display the problem with the selected math operator as in the example below
num1
+ num2
-------
If student answer is the same as the correct answer
Send a message: Congratulations! That is right!
Else
Send a message: Sorry, the correct answer is “correct answer”
} while (choice!= 4);
End of program;
Sample runs:
Menu
1. Addition problem
2. Subtraction problem
3. Multiplication problem
4. Quit this program
