Why is my power operator (^) not working?

Well, first off, the ^ operator in C/C++ is the bit-wise XOR. It has nothing to do with powers.

Now, regarding your problem with using the pow() function, some googling shows that casting one of the arguments to double helps:

result = (int) pow((double) a,i);

Note that I also cast the result to int as all pow() overloads return double, not int. I don’t have a MS compiler available so I couldn’t check the code above, though.

Since C99, there are also float and long double functions called powf and powl respectively, if that is of any help.
