Factorial function

[guru23]

I'm trying to get the factorial of 5, for example, but it won't let me. I've tried almost everything but I can't seem to figure it out. Thanks for taking the time to read.

#include <iostream>
using namespace std;

void factorial(int n) {
    
    for(int i = 1; i <= n; i++) {
        cout << 1 * (n - 1);
    }
}

int main() {
    
    int x;
    
    cout << "Enter a number to see its factorial: ";
    cin >> x;
    
    factorial(x);
}

Output:

Enter a number to see its factorial: 5
44444

Hi,

On lines 6 and 7, which variable is being incremented? Which one are you printing?

I want to increment variable i (1, 2, 3, 4, 5) and as the incrementation is occurring, I want it to get multiplied, too. I want to n print the factorial of the inputted number.

I fully understand what you want to do, but I am trying to get you to think about what is happening, perhaps I should have said which variable name is being incremented? i or n ?

To do this you need another variable. We start with 1 * 2, we need to put the answer to that somewhere.

The answer to this problem is exactly the same as a previous Topic you had.
