Question

I would like to know how to determine the highest number and the lowest number out of whatever numbers the user inputs. We’re supposed to display those after the user enters 99. Everything I found is using arrays, and we’ve not yet learned those. Please help!

        string input;
        int input2;
        Console.WriteLine("Enter an integer");
        input = Console.ReadLine();
        input2 = Convert.ToInt32(input);


        while (input2 != 99)
        {
            Console.WriteLine("Enter an integer");
            input = Console.ReadLine();
            input2 = Convert.ToInt32(input);
        }

Answer 1

The idea of imperative programming is to give a sequence of statements (an algorithm) that mutate state (a set of variables) until it contains the desired result.

For example, your program changes the contents of the variables input and input2 until input2 contains the value 99.

To find the highest and lowest integer, define two variables, highest and lowest. Change their contents in the while loop such that, after each iteration, they contain the highest and lowest integer respectively, taking the current input value into account.
