expontants??

Ok so can someone help me with adding exponants to a caculator

how about
double exp (double) from the <math.h> library
that is e to the power of x .

Just make a loop out of it, something like this:

Code:

---

int Base = 2, Exp = 5, ctr, Result;
Result = Base;
for (ctr = 0; ctr < Exp; ctr++)
{
    Result *= Base;
}

---

That will calculate the value Base to the power of Exp, and puts teh calculated value in Result. That doesn't account for exponents that are less than or equal to 0 (5^0 or 5^-24). But you can easily modify the result to get that.

Math.h is a header, not a library. And don't use math.h (it's deprecated).

Instead, use cmath and the std namespace.
