    Why do we need recursive functions when we have loops?

    This works but I don't understand how. How does C++ know that the second 'return' wants the returned 'm' on the final recursion...
    #include
    using namespace std;
    //factorial calculator using a recursive function
    int factorial_calculator(int m, int n) {
    if (m == n)
    return m;
    return n*factorial_calculator(m, n + 1);
    }
    int main()
    {
    int m, n=1;
    cout > m;
    cout

    //I used double instead of int so that I avoid getting overflow error when using larger numbers (and by larger, something bigger than 10 lol)
    #include
    using namespace std;
    double factorial(double m, double n);
    int main()
    {
    cout n;
    cout

    I was able to run 'n' all of the way to '4699'!

    Recursion confused me so badly I dropped out of my comp sci degree fifteen years ago.

    Ma'am, please make tutorials on data structures and algorithm most important ly dynamic programming in C++ because every word you say, clicks my mind.
