Thread: Power function

Hey guys, this is a realy simple question (I think). So I'm supposed to write a function that elevates a number to some other number (function inputs). Here it is as presented in the solution:

Code:

float pot(float x, int n){


    float res;
    int i;


    for(i=1, res=1.0; i<=n; i++)
        res*=x;
    return res;
}

The only question that I have is, if n=0 the output is 1 (as it should be!). Where in this code does that happen?

Since you have initialized in for loop res = 1.0.

So, because n<i it just returns the value with what it was initialized with?
