Question

Write a program that uses a function power(base,exponent) which when invoked return sbase exponent C++

Answer 1

#include <iostream>
using namespace std;
int power(int base, int exponent)
{
   int tmp;
   if (exponent == 0) {
      return 1;
   }
   else if (exponent % 2 == 0) {
      tmp = power(base, exponent / 2);
      return tmp*tmp;
   }
   else {
      tmp = power(base, exponent / 2);
      return base*tmp*tmp;
   }
}

int main() {
   int base, exponent;
   cout<<"Enter base: ";
   cin>>base;
   cout<<"Enter exponent: ";
   cin>>exponent;
   cout<<"Result: "<< power(base, exponent);
   return 0;
}
