C++ Program to Calculate Power Using Recursion

# C++ Program to Calculate Power Using Recursion

In this example, we will learn how to calculates the power of a number using recursion where base and exponent is entered by the user.

To understand this example, you should have the knowledge of the following C++ programming topics:

## Example: Program to Compute 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;
}``````

Output 1

```Enter base number: 3
Enter power number(positive integer): 4
3^4 = 81```

##### Working

In this program, This technique can only calculate power if the exponent is a positive integer.

To find power of any number, you can use `pow()` function.

`result = pow(base, exponent);`
