在C中找到立方根

Question

我试图找到该卷的立方根，但它无法正常工作。我认为浮点有问题，但不知道如何修复它。如您所见，Cube Root应该是3不是37

#include <stdio.h>


int main() {
    int width;
    int length;
    int height;
    int volume;
    double volumes;

    printf("write width  ");
    scanf("%d", &width);

    printf("write length  ");
    scanf("%d", &length);

    printf("write height  ");
    scanf("%d", &height);


    volume = width * length * height;
    
    printf("volume is %d  \n", volume);

    volumes =  (double)pow((double)volume,1.0/ 3.0);

    printf("cube root is %f   \n", volumes);

    return 0;
}

Answer 1

您可以在 math.h 文件中使用 cbrt() 函数

#include<math.h>

//cbrt(x) to get cube root of x :)
    
printf("cube root is %f   \n",cbrt(x));
