Answer:
// here is code in c++.
#include <bits/stdc++.h>
using namespace std;
// recursive function to calculate power of number
int cal_pow( int b_num, int e_num )
{
if ( e_num > 1 )
return b_num * cal_pow( b_num, e_num - 1 );
else
return b_num;
}
int main()
{
// variables to store inputs
int b_num, e_num;
cout <<"Enter the base (int): ";
//read the base
cin >> b_num;
cout << "Enter the exponent (int): ";
// read the exponent
cin >> e_num;
// call the function and print the output.
cout << b_num << " to the " << e_num << " power is: "
<< cal_pow( b_num, e_num ) << endl;
return 0;
}
//
Explanation:
Read value of base and exponent from user. Call the function cal_pow() with parameter base and exponent. In this function, it will call itself and multiply base value while exponent becomes 1.When exponent becomes 1 then base value will be return by the recursive function. In the last recursive call it will give the base to power exponent
Output:
Enter the base (int): 3
Enter the exponent (int): 5
3 to the 5 power is: 243
