I need help writing a math tutor program that goes under these guidlines
---------------------------------
When you run your Math Tutor program the output should look like the following.
Important to remember that you should generate random numbers between 10 and 50.

Thank you for using Math Tutor.

-----This program is suppose to loop until the user selects option 4.------------ Heres what I have and I have become very lost------

#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;

int main(void)
{
	srand(time(0));
	int choice = 0;
	int digits = 1;
    
    // Show menu and get users choice
    cout << " Math Tutor - Main Menu \n";
    cout << "Choose your operation to practice (1-4): \n";
    cout << "1. Addition \n";
    cout << "2. Subtraction \n";
    cout << "3. Multiplication \n";
    cout << "4. Exit program \n";
    cin  >> choice;
    
    
    //Validate menu selection
    while ((choice < 1) || (choice > 4))
  
    {
        
        cout << "Incorrect menu selection. Please choose between 1 and 4. ";
        cin >> choice;
        
       
    }

    while (choice == 4)

    int num1 = 1;
    int num2 = 2;
    int total = 3;
    int answer = 3;
 
    for (int i = digits; i > 0; i--)
    {
        num1 *= 100;
        num1 += (rand() % 9) + 1;
    }
    for (int i = digits; i > 0; i--)
    {
        num2 *= 100;
        num2 += (rand() % 9) + 1;
    }

    }
    return 0;
        
  Put the code you need help with here.

I kind of cleaned your code up for you :) Let me know if you need anything else!

#include <iostream>
#include <ctime>
using namespace std;

int main(void)
{
	int choice;
	int num1;
	int num2;
	int total;
	int answer;

	do
	{
		//Get random numbers
		srand(time(0));
		num1 = rand() % 100;
		num2 = rand() % 100;

		// Show menu and get users choice
		cout << " Math Tutor - Main Menu \n";
		cout << "Choose your operation to practice (1-4): \n";
		cout << "1. Addition \n";
		cout << "2. Subtraction \n";
		cout << "3. Multiplication \n";
		cout << "4. Exit program \n";
		cin >> choice;

		//Validate menu selection
		while ((choice < 1) || (choice > 4))
		{
			cout << "Incorrect menu selection. Please choose between 1 and 4. ";
			cin >> choice;
		}
		if (choice == 4)
		{
			cout << "Thank you for using Math Tutor! " << endl;
			return 0;
		}
		else if (choice == 1)
		{
			cout << "Working with addition: ";
			cout << num1 << " + " << num2 << endl;
		}
		else if (choice == 2)
		{
			cout << "Working with subtraction: ";
			cout << num1 << " - " << num2 << endl;
		}
		else if (choice == 3)
		{
			cout << "Working with multiplication: ";
			cout << num1 << " x " << num2 << endl;
		}

		//Display equation
		cin >> answer;

		switch (choice)
		{
		case 1:
			total = num1 + num2;
			break;
		case 2:
			total = num1 - num2;
			break;
		case 3:
			total = num1 * num2;
		}

		if (answer == total)
		{
			cout << endl;
			cout << " Your answer is " << answer << endl;
			cout << " The correct answer is " << total << " Congratulations" << endl;
		}
		else
		{
			cout << endl;
			cout << " Your answer is " << answer << endl;
			cout << " The correct answer is " << total << " Sorry !" << endl;
		}
	} while (1);
}
