    Angry While Loops

    I'm trying to write a program with a loop that has the user enter 2 numbers and ends only when half the product of the 2 numbers entered is less than either number

    Here is what i have so far:
    Code:
    #include <iostream.h>
    
    int main()
    {
    	// Declaring Variables
    	int hold;
    	int num1, num2;
    	int product;
    	
    	// Inputting Numbers
    	cout << "Enter 1st number : ";
    	cin  >> num1;
    	cout << "Enter 2nd number : ";
    	cin  >> num2;
    	
    	// While Loop
    	while (product !=0)
    	{
    		product = ((num1 * num2)/2);
    		cout << product << endl;
    	break;
    	}
    	cin >> hold;
    	return 0;
    }

    changes are in bold
    Code:
    #include <iostream.h>
    
    int main()
    {
    // Declaring Variables
    int hold;
    int num1, num2;
    int product;
    
    // While Loop
     // while (product !=0)
    do
    {
    
    // Inputting Numbers
    cout << "Enter 1st number : ";
    cin  >> num1;
    cout << "Enter 2nd number : ";
    cin  >> num2;
    
    // product = ((num1 * num2)/2);
    // don't call this variable "product" if it doesn't hold the product
    product = num1 * num2;
    cout << product << endl;
     // break;
    }while(product/2 >= num1 && product/2 >= num2);
    cin >> hold; // this could just be cin.get(); 
    return 0;
    }
    EDIT: I didn't notice that just half the product was being stored in "product"

    My code prompts the user for two numbers, and does so until one-half the product of said two numbers is less than at least one of the two numbers entered.

    I suppose you want something different but are having trouble putting it into words.

    Codulation, if you run the program and let's say for example you input 24 and 36, the program does ((24*36)/2) but I think I'm the one having trouble explaning my problem so I'll restate it.
    Let's use the example of inputting 24 and 36. I want the program to divide until that number is less than the numbers inputted which in this case would be 24 and 36. I'm sorry for not explaning the program correctly.

    No prob.

    Code:
    #include <iostream.h>
    
    int main()
    {
    // Declaring Variables
    int hold;
    int num1, num2;
    int product;
    
    // Inputting Numbers
    cout << "Enter 1st number : ";
    cin  >> num1;
    cout << "Enter 2nd number : ";
    cin  >> num2;
    
    product = num1 * num2;
    
    // While Loop
    do
    {
      product /= 2;
      cout << "Current product is: " << product << endl;
    }while(product >= num1 && product >= num2);
    
    cin >> hold; 
    return 0;
    }

    Thanks Codulation. I'm sorry for not explaning it correctly and I'm new to c++ and learning by myself. Thank you so much.

    No problem at all!

    > I'm new to c++ and learning by myself.

    I wish you the best of luck. Ask lots of questions and above all just try things over and over. You have a fun road ahead
