Calculate power of a number using recursion in C++

 Calculate power of a number using recursion in C++

In this article, we will discuss the concept of Calculate power of a number  using recursion in C++ programming language

In this post, we will learn how to  find the power of a number using a recursive function in C language

Program 1

#include <iostream>
#include <conio.h>
using namespace std;

int find_Power(int num1,int num2);
int main()
{
    int base, powerValue, result;

    cout<<"Enter base number: ";
    cin>>base;

    cout<<"Enter power number: ";
    cin>>powerValue;

    result=find_Power(base,powerValue);

    cout<<base<<"^"<<powerValue<<" is "<<result;
    getch();
    return 0;
}

int find_Power(int base, int powerValue)
{
    if(powerValue !=0)
        return (base*find_Power(base,powerValue-1));
    else
        return 1;
}

When the above code is executed, it produces the following results

Enter base number: 3
Enter power number: 4
3^4 is 81

 

In the above program, the function find_Power() is a recursive function. When the power  is not equal to 0 the function recursively call it self to calculate power

When the power  is  equal to 0 the function return 1 – any number raised to the power of 0 is 1

you want to find power of any number, you can use pow() function in C++ language
