Visual Studio Code – I want to write a cashier program using C# while, it should add the final total but it just keeps showing the price right underneath

I wanted it to look like this:

And here’s my result:

actual

This is my code

private static void Main(string[] args)
{
    Console.WriteLine("CASHIER");
    Console.WriteLine("Enter Quantity of Products: ");
    
    int qty = Convert.ToInt32(Console.ReadLine());

    if (qty > 5)
    {
        Console.WriteLine("Maximum of 5 products");
    } 
    else 
    {
        int i = 1;

        while (i <= qty)
        {
            Console.WriteLine(i);
            i++;

            Console.WriteLine("Enter Price: ");
            int price = Convert.ToInt32(Console.ReadLine());

            int total = + price;
            Console.WriteLine("Total: " + total);
        }
    }
}

    Not sure, that I fully understand your question.
    But you should consider declaring your total outside your loop and doing total +=

        int i = 1;
    int total = 0;
    while (i <= qty)
    {
        Console.WriteLine(i);
        i++;
        Console.WriteLine("Enter Price: ");
        int price = Convert.ToInt32(Console.ReadLine());

        total += price;
        Console.WriteLine("Total: " + total);
    }

    Your

    int total = + price;

    inside the loop redeclares total as a new variable each time your loop executed its block and you always assign price in a positive manner to it instead of adding price to the previous total. The solution is to:

    • declare total outside the loop and initialize it with 0
    • add price to it at each step
    private static void Main(string[] args)
    {
        Console.WriteLine("CASHIER");
        Console.WriteLine("Enter Quantity of Products: ");
        
        int qty = Convert.ToInt32(Console.ReadLine());

        int total = 0;

        if (qty > 5){
            Console.WriteLine("5 Maximum Products");
        } else {
            int i = 1;
            while (i <= qty ){
                Console.WriteLine(i);
                i++;
            Console.WriteLine("Enter Price: ");
            int price = Convert.ToInt32(Console.ReadLine());

            total += price;
            Console.WriteLine("Total: " + total);
            }
        }
    }

    If you want to show total only once, at the very end, you need to move your last Console.WriteLine outside (after) the loop.
