How to express nth power in C?

There are two ways to express nth power in C:

1. Use the pow() function

#include <cmath>

double result = pow(base, exponent);

where:

• base is the base.
• exponent is the exponent.
• result is the result.

2. Use ^ operator

double result = base ^ exponent;

Example:

Calculate 2 5th power:

• Use pow() Function:

  #include <cmath>
  
  double result = pow(2, 5);

  Copy after login

• Use ^ Operator:

  double result = 2 ^ 5;

  Copy after login

  Note:

  • ##^ operator has higher priority than * and /, but lower than and -. Therefore, you need to be careful when using the ^ operator. The
  pow() function is a function in the standard library, and the
  • ^ operator is a form of C operator overloading.
