How to express the nth power of x in C language

In C language, it represents the nth power of x

In C language In , there are two main ways to express the nth power of x:

1. Use the pow() function

<code class="c">#include <math.h>

double result = pow(x, n);</code>
  • pow() function Accepts two parameters: the number x to be exponentiated and the power n.
  • It returns the value of x raised to the nth power.
  • It needs to include the <math.h> header file.

2. Use the exponent operator

<code class="c">double result = x ^ n;</code>
  • Exponent operator (^)directly promote x to n times power.
  • It has higher precedence than multiplication and division, so parentheses are not required when using it.

Note:

  • Both methods work with integers and floating-point powers.
  • If n is negative, the result will be x raised to the 1/n power.
  • If x is 0 and n is negative, the result is undefined.
