How to express x to the nth power in C language

There are two ways to represent x raised to the nth power in the C language: using the pow() function, that is, pow(x, n); using the exponential operator, that is, x ** n.

How to express the nth power of x in C language

In C language, you can use the following two methods The way to express x to the nth power:

1. Use the pow() function

<code>#include <math.h>

double pow(double x, double n); // 计算 x 的 n 次方</code>

• Usepow(x, n) The function computes x raised to the nth power.
• x is the base and n is the exponent.
• The return type is double.

2. Use the exponent operator

<code>x ** n; // 计算 x 的 n 次方</code>

• Use the exponent operator ()** to calculate n of x second power.
• x is the base and n is the exponent.
• x and n must be of integer type.
