How to calculate power in C

Question

How do I calculate a power in C, and do you have to include anything? I have tried to include math.h, however it didn't work. What is de difference between a int and a double in this case.

Answer 1

Welcome to SO! To calculate a power in C, the best way is to use the function pow(). It takes two double arguments: the first is the number that will be raised by the power, and the second argument is the power amount itself.

So: double z = pow(double x, double y);

Then the result will be saved into the double z. You will have to use the math.h library in order to use this function.
