How to write n raised to the nth power in c++

Compute n to the power of n in C: Use the pow() function, located in the header file. pow(base, exponent), where base is the number to be raised to a power and exponent is the power. For example, pow(3, 4) calculates 3 raised to the 4th power, which is 81.

How to calculate n raised to the power of n in C

In C, you can use pow() The function computes n raised to the nth power. This function is located in the header file, and the syntax is as follows:

<code class="cpp">double pow(double base, double exponent);</code>

where:

• base is the number whose power is to be calculated.
• exponent is a power.

Usage:

To calculate n raised to the power n, use the following code:

<code class="cpp">double result = pow(n, n);</code>

Example:

The following is an example showing how to calculate 3 raised to the 4th power:

<code class="cpp">#include <iostream>
#include <cmath>

using namespace std;

int main() {
  int n = 3;
  double result = pow(n, n);
  cout << "3 的 4 次方为：" << result << endl;

  return 0;
}</code>

Output:

<code>3 的 4 次方为：81</code>
