❔ help with an exercise

I've encountered a weird problem that idk how to fix. Say we've got a string "31131123521" how do i make it so each number of the string is multiplied by one another so the string we have got will be equal to 3 * 1 * 1 * 3 * 1 * 1 * 2 * 3 * 5 * 2 * 1 (this is equal to 540). I have trouble finding a patter or solution to this when it seems very simple. Given a string i just want to multiply each number inside of it

First, you'll need to get an array of numbers from this string Use the fact that a string already is an array of chars And that a method char.GetNumericValue() method exists You'll need to do the multiplications in a loop And keep the result outside of the loop

mind writing some quick code for this ; ; ? heres the structure 
        string wholeString = Console.ReadLine();
        string multiplicationNumbers = "";
        foreach (var letter in wholeString)
        {
            if (char.IsDigit(letter))
            {
                multiplicationNumbers += letter;
            }
        }
        Console.WriteLine(multiplicationNumbers);
        for (int i = 0; i < multiplicationNumbers.Length; i++)
        {
            
        }
        string wholeString = Console.ReadLine();
        string multiplicationNumbers = "";
        foreach (var letter in wholeString)
        {
            if (char.IsDigit(letter))
            {
                multiplicationNumbers += letter;
            }
        }
        Console.WriteLine(multiplicationNumbers);
        for (int i = 0; i < multiplicationNumbers.Length; i++)
        {
            
        }
i dont know how to like, i even tried using chatGPT for this and still nothing i dont know in what pattern to multiply the numbers

a huge number in the millions always comes up

There's no pattern
A
Angius•398d ago
That's how you multiply
D
Despy()•398d ago
when in fact the answer is 540 i know okay can yall get my code and do it then
A
Angius•398d ago
Nope Not doing your homework for you
S
Shinigami•398d ago
We can tell how to do it You could really google what @Angius just told How to make a string into char array?
D
Despy()•398d ago
thats not my problem
S
Shinigami•398d ago
Then?
D
Despy()•398d ago
i know to convert chars into ints and such. the problem is when i try doing it with code the answer comes up as smth ludicrous in the millions. keep in mind this is the string "31131123521"
A
Angius•398d ago
Show the code, then
D
Despy()•398d ago
when in fact the answer to 3 * 1 * 1 * 3 * 1 * 1 * 2 * 3 * 5 * 2 * 1 is 540
A
Angius•398d ago
Show your code that converts the string into an array of ints
S
Shinigami•398d ago
Yes If the logic for how you're multiplying is flawed then it'd obv show huge number
D
Despy()•398d ago
it is flawed thats what im asking for ; ; the logic itself
A
Angius•398d ago
Well, show the code
D
Despy()•398d ago
sec

Shinigami•398d ago
Show us what you've done, for us to understand where u went wrong
D
Despy()•398d ago
sorry i had to do smth 
string str = "31131123521";
int result = 1;
foreach (char c in str)
{
    int digit = int.Parse(c.ToString());
    result *= digit;
}
Console.WriteLine(result);
string str = "31131123521";
int result = 1;
foreach (char c in str)
{
    int digit = int.Parse(c.ToString());
    result *= digit;
}
Console.WriteLine(result);
