How to express the nth power of x in C language

In C language, you can use the pow() function to calculate the nth power of x. Its syntax is: pow(double x, double y); it uses x as the base, y as the exponent, and returns x to the power of y.

In C language, the nth power of x represents

In C language, you can use the pow() function Calculates x raised to the nth power.

pow() function syntax

<code class="c">double pow(double x, double y);</code>

Parameter description

• x: base
• y: Exponent

Return value

Returns the result of x raised to the power of y. If y is an integer, it returns the double type, otherwise it returns the long double type. .

Code example

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

int main() {
    double x, n;

    printf("请输入底数 x：");
    scanf("%lf", &x);
    printf("请输入指数 n：");
    scanf("%lf", &n);

    double result = pow(x, n);
    printf("x 的 n 次幂为：%.2f\n", result);

    return 0;
}</code>

Output example

<code>请输入底数 x：5
请输入指数 n：3
x 的 n 次幂为：125.00</code>
