利用类求某个学生语文数学的总分和平均分

利用类求某个学生语文数学的总分和平均分#include<iostream.h>classstu{private:charname[20];floatchinese;floatmath;public: voidsetstudent() {cin>>name>>chinese>>math; } floatsum() {floatz; z=chinese+math; returnz; } floataverage() {floatz; z=(chinese+math)/2.0; returnz; } voidshow() {cout<<"name:"<<name<<"chinese:"<<chinese<<"math:"<<math<<endl; } char*getname() {char*z; z=name; returnz; }};intmain(){stut;t.setstudent();cout<<t.sum()<<endl;cout<<t.average()<<endl;t.show();cout<<t.getname()<<endl;return0;}第二章课后习题6利用类求3个长方柱的体积#include<iostream.h>classvolume{private:floatlength;floatwidth;floatheight;public: voidsetvolume() {cin>>length>>width>>height; } floatv() {floatz; z=length*width*height; returnz; } voidshow() {cout<<"length:"<<length<<"width:"<<width<<"height:"<<height; }};intmain(){volumet,t2,t3;t.setvolume();cout<<t.v()<<endl;t.show();t2.setvolume();cout<<t2.v()<<endl;t2.show();t3.setvolume();cout<<t3.v()<<endl;t3.show();return0;}第二章课后习题5将例2.4改写成多文件的程序将下面类的定义放在头文件Array_max．h中即include中classArray_max{public:voidset_value();voidmax_value();voidshow_value();private: intarray[10]; intmax;};将下面成员函数的定义放在源文件Array_max．ｃｐｐ中#include<iostream>#include"Array_max.h"voidArray_max::set_value(){inti;for(i=0;i<10;i++) cin>>array[i];}voidArray_max::max_value(){inti;max=array[0];for(i=0;i<10;i++) if(array[i]>max) max=array[i];}voidArray_max::show_value(){cout<<"max="<<max;}将主函数放在源文件filel.cpp中#include<iostream.h>#include"Array_max.h"intmain(){ Array_ma
