In this shot, we will discuss how to calculate **the power of a number**. In other words, we will learn how to calculate the power of `base` to `exponent`. 

> Power of `base` to `exponent` =  $base^{exponent}$

For example, we have $2^{3}$, which means 2 will be multiplied 3 times, which is 2 * 2 * 2. This gives an output of 8.

# Solution
We will use a loop to calculate the power of a number. The loop will execute until the condition becomes `false`, after which the loop will be terminated. It will execute as many times as we give the value of the `exponent`.

To understand this better, let's look at the code snippet below.







#include <iostream>
using namespace std;

int main() {

  int base, exponent, counter, result = 1;
  cin >> base >> exponent ;

  for (counter = 1; counter <= exponent ; counter++)
    result *= base;

  cout << "The power of a number is :" << result ;
  return 0;
}

# Explanation
>In order to pass the input to the code, you need to pass two numbers, the `base` and the `exponent`, in the above box, like so: `4 5`.
* In *line 6*, we initialize the `base`, `exponent`, `counter` variables and `result = 1`. 

* In *line 7*, we take the input as `base` and `exponent`. 

* In *lines 9 and 10*, we run a loop and then multiply the `base` with itself `exponent` times.

* In *line 12,* we print the result.

In this way, we can calculate the power of a number in C++ with loops.

How to calculate the power of a number in C++

Use a loop to multiply the base by itself exponent times, initializing result to 1.
