❔ factorial using equation

So i am stuck on this task where i have to also use equation for example 11 =1 12=2 23=6 and i still don't get the for cycles/loops so im struggling on finish product, i have almost everything except the 1st number which is last factorials anserw. as of right now it is 11=1 22=2 63=6 here is the code i have right now, it has mistakes i know but im learning. static void Main(string[] args) { Console.WriteLine("Please enter your number: "); int n = int.Parse(Console.ReadLine()); int factorial = 1; int factorialres = 1; for (int i = 1; i <= n; i++) { factorial = i; factorialres = factorial; Console.WriteLine(factorialres + "" + i + " = " +factorial); } }

you are assigning the value of i to factorial in each iteration of the loop, which is incorrect. you need to multiply the current value of factorial with the value of i. here is the correct way you can do it

static void Main(string[] args)
{
    Console.WriteLine("Please enter your number: ");
    int n = int.Parse(Console.ReadLine());

    int factorial = 1;
    int factorialres = 1;
    for (int i = 1; i <= n; i++)
    {
        factorial *= i;
        factorialres = factorial;
        Console.WriteLine(factorialres + "" + i + " = " + factorial);
    }
}

static void Main(string[] args)
{
    Console.WriteLine("Please enter your number: ");
    int n = int.Parse(Console.ReadLine());

    int factorial = 1;
    int factorialres = 1;
    for (int i = 1; i <= n; i++)
    {
        factorial *= i;
        factorialres = factorial;
        Console.WriteLine(factorialres + "" + i + " = " + factorial);
    }
}
