用C++的类来封装立方体的数据和操作,并实现各操作

#include <stdio.h>

// 定义立方体类
typedef struct {
    double length;
    double width;
    double height;
} Cube;

// 初始化立方体
void Cube_Init(Cube* cube, double length, double width, double height) {
    cube->length = length;
    cube->width = width;
    cube->height = height;
}

// 计算立方体体积
double Cube_Volume(Cube* cube) {
    return cube->length * cube->width * cube->height;
}

// 计算立方体表面积
double Cube_SurfaceArea(Cube* cube) {
    return 2 * (cube->length * cube->width + cube->length * cube->height + cube->width * cube->height);
}

// 打印立方体信息
void Cube_PrintInfo(Cube* cube) {
    printf("Cube length: %lf\n", cube->length);
    printf("Cube width: %lf\n", cube->width);
    printf("Cube height: %lf\n", cube->height);
    printf("Cube volume: %lf\n", Cube_Volume(cube));
    printf("Cube surface area: %lf\n", Cube_SurfaceArea(cube));
}

int main() {
    Cube cube;
    Cube_Init(&cube, 2.0, 3.0, 4.0);
    Cube_PrintInfo(&cube);
    return 0;
}
