    Question Recursive Function

    I am trying to work with the recursive function. I would like to implement a program using the recursive function power that when invoked, returns 3 to the power of 4. e.g., (3,4) = 3*3*3*3. I would like to assume that the exponent is an integer greater than or equal to 1. I would like to take the user input for the base.

    My thoughjt process is that the recursion step would use the relationship:

    base[exponent] = base*base [exponent]-1

    Looks good so far
    Now just write the code for it - pretty much as you've written it now really

    Dont forget the simple condition which stops the recursive calls.

    If this is an excersice, it's a bad example of recursion. An iteration had been much better in this problem.

    Anyway, something like this should solve it:
    Code:
    int MyPower(int Base, int Exp)
    {
       if(Exp <= 0) return 1;
       else return Base * MyPower(Base, Exp - 1);
    }
