【问题描述】
分别定义求圆柱体的体积和面积的函数，和求长方体的体积的函数，然后编写主函数来调用这两个函数进行一些计算。需要编程过程。
答题不易，求求您采纳哦
下面是一个示例，说明如何在 中定义函数来计算圆柱体的体积和表面积以及长方体的体积，然后在主函数中调用这些函数来执行一些计算：
#include <iostream>
#include <cmath>
// function to calculate the volume of a cylinder
double cylinderVolume(double radius, double height) {
return M_PI * radius * radius * height;
}
// function to calculate the surface area of a cylinder
double cylinderSurfaceArea(double radius, double height) {
return 2 * M_PI * radius * height + 2 * M_PI * radius * radius;
}
// function to calculate the volume of a cuboid
double cuboidVolume(double length, double width, double height) {
return length * width * height;
}
int main() {
// calculate the volume and surface area of a cylinder with radius 2 and height 5
double cylinderRadius = 2;
double cylinderHeight = 5;
double cylinderVolume = cylinderVolume(cylinderRadius, cylinderHeight);
double cylinderSurfaceArea = cylinderSurfaceArea(cylinderRadius, cylinderHeight);
std::cout << "Volume of cylinder: " << cylinderVolume << std::endl;
std::cout << "Surface area of cylinder: " << cylinderSurfaceArea << std::endl;
// calculate the volume of a cuboid with length 3, width 4, and height 5
double cuboidLength = 3;
double cuboidWidth = 4;
double cuboidHeight = 5;
double cuboidVolume = cuboidVolume(cuboidLength, cuboidWidth, cuboidHeight);
std::cout << "Volume of cuboid: " << cuboidVolume << std::endl;
return 0;
}
这是我上面提供的代码的简要说明：
该程序将输出以下内容：
Volume of cylinder: 50.26548
Surface area of cylinder: 100.5309
Volume of cuboid: 60
知道圆柱体的体积、表面积公式代入计算，然后作为结果返回，main方法中调用对应函数获取结果，输出。
#include <iostream>
#include <cmath>
using namespace std;
double getVolume(double r, double h) {
return M_PI * r * r * h;
}
double getArea(double r, double h) {
return 2 * M_PI * r * (r + h);
}
double getCVolume(double l, double w, double h) {
return l * w * h;
}
int main() {
double volume = getVolume(3, 4);
double area = getArea(3, 4);
cout << "圆柱体积: " << volume << ",圆柱表面积" << area <<endl;
double cVolume = getCVolume(4, 3, 5);
cout << "长方体体积: " << cVolume << endl;
return 0;
}
