Creating my own functions.

[midknight5]

Hey guys, as I progress through my C++ education ive started getting into headers and drivers, so I figured for good practice I would make my own header file that contains function prototypes and a implementation file for testing.

I want to make my own version of pow, so ive made a functions called:
double power(double x, double y);

Now we all know how a power works, its multiplies number x by itself y number of times but im unsure of how to implement this. I figured a for loop would work.

for (int i = 0; i < y; i++)
{
// something to do with x*x?
}

But from here I get stuck, any ideas?

Have a temporary variavle something like this:
[code=c]
temp double;
temp = x;
<your for loop>
temp= temp * x;
<end of loop>
return temp;
