This is exactly what I was looking for. You showed me where I needed to put the while loop when the user is the one that changes the conditional variable.

so i added this code to my already working algorithm but when  I do scanf("%c", again); it give me an error saying "fornat specifies as char but the argument has type int). could you please tell how to fix this?

Laurethe NoLastName I'd assume it is a C program, so first declare it as char, and place an ampersand '&' before the variable name when asking for input, most probably like scanf("%c", &"variable_name")

I have copied this however when I type anything including y it just goes prompts me with "Press any key to continue . . . " and then closes. Here's my code: https://pastebin.com/EiaTSady

Couple of issues first off. You really only need to #include <iostream> you also declare the variables multiple1, 2 outside of the loop and again first thing in the loop--this isn't necessary. Take a look at my simple calculator program as an example--you can use this framework as a basis for your loop. //Area Calculator for a rectangle // #include <iostream> int main() { double length = 0; double width = 0; double Area = length * width; char again = 'Y'; char ch = 253; //This assigns the ASCII value of 253 to ch in order to print the upper carrot exponent while (again == 'y' || again == 'Y')//begins while loop { std::cout << "This program computes the area of a given rectangle"; std::cout << "\n\nPlease input a custom width of a rectangle: \n"; std::cin >> width; std::cout << "Please input a custom length of a rectangle: \n"; std::cin >> length; Area = length * width; std::cout << "The custom area of your entered rectangle is: " << Area<<ch; std::cout << "\nWould you like to compute another area? (Y-Yes) (N-No): "; std::cin >> again; } //ends while loop std::cout << "Thanks for using the calculator!"; //exit message return 0; }

Awesome videos. You elaborate the things so nicely and slowly that even a child can start coding. :) You EARNED a subscriber Prof Gustin. Keep up the work.
