//Write your code here

struct MyException: public exception
{
    const char* what () const throw()       //const throw() means that this function won't throw any exception.
    {
        return "n and p should be non-negative";
    }
};


class Calculator
{
public:

    int power(int n, int p){
        if((n<0)||(p<0)) throw MyException();
       
        int result=1;               //result = pow(n,p) works as well.
       
        for(int i=0;i<p;i++){         
            result *= n;
        }
       
        return result;
    }
