Question

Write a program to compute a^n (a power n) using recursion

Answer 1

Answer:

Example: Program to Computer Power Using Recursion

#include <iostream>

using namespace std;

int calculatePower(int, int);

int main()

{

   int base, powerRaised, result;

   cout << "Enter base number: ";

   cin >> base;

   cout << "Enter power number(positive integer): ";

   cin >> powerRaised;

   result = calculatePower(base, powerRaised);

   cout << base << "^" << powerRaised << " = " << result;

   return 0;

}

int calculatePower(int base, int powerRaised)

{

   if (powerRaised != 0)

       return (base*calculatePower(base, powerRaised-1));

   else

       return 1;
