PowerOf Function
Code:

```/* Title: c5 Review 9 (c05r09) */ #include <iostream.h> // ---------------------------------------- void Introduction() { IGNORE THIS PART } // ---------------------------------------- double PowerOf(double x, int n) { CODE NEEDED HERE         return (); } // ---------------------------------------- int main() {         double x;         cout << "Enter the base number: ";         cin >> x;         int n;         cout << "Enter the exponent: ";         cin >> n;         PowerOf(x, n);         return(0); }```
I need help figuring out how to get a number to a power and it displaying the results. What I mean is, I define x as 2 and say n as 3. That would be 2^3, or the number 8. Inside the PowerOf() function, I can't figure out the code to do that. I know it has something to do with a for loop though.

How would you do it on paper? Or with a calculator? Once you know that the code for such a simple function practically writes itself.

I know how to do it on the calculator, and on paper, I just can't get the for statement to give me what I want. It's probably a really simple 3-4 line code I'm just dancing around. Help?

Code:

```double PowerOf ( double base, int n ) {   double ret = 1.0;   for ( int i = 0; i < n; i++ ) {     ret *= base;   }     return ret; }```
