编写基于对象的程序,求5个长方柱的体积和表面积。长方柱类Bulk的数据成员包括长(length)、宽(width)、高(heigth)等。· 设计成员函数output,在main中调用输出这5个长方柱的体积和表面积;
#include <iostream> using namespace std; class Bulk { public: Bulk(double x=1.0,double y=1.0,double z=1.0):lengh(x),width(y),height(z) {}; void get_value(); void show(); private: double lengh; double width; double height; }; void Bulk::get_value() { cout<<"请输入长方体的长、宽、高:"; cin>>lengh>>width>>height; } void Bulk::show() { cout<<"表面积为:"<<2*(lengh*width+lengh*height+width*height)<<endl; cout<<"体积为:"<<lengh*width*height<<endl; } int main() { Bulk b[5]= {Bulk(2.3,4.5,6.7),Bulk(1.5,3.4),Bulk(10.5)}; b[4].get_value(); for(int i=0; i<5; ++i) { cout<<"第"<<i+1<<"个长方体"<<endl; b[i].show(); } return 0; }
运行结果:
