How do I use power in C++?

Question

I’m making a simple calculator, and I wanted to add power.

I’ve tried to Pow() and did not give, need to add some class?

Answer 1

Is not Pow, is pow.

Upper and lower case make a difference in C++

And the library is math:

#include <math.h>

int main ()
{
  printf ("5 ^ 3 = %f\n", pow(5.0, 3.0));
  return 0;
}
