1、上機(jī)考試題1定義盒子Box類，要求具有以下成員變量：長(zhǎng)、寬、高分別為length，with，high；具有一個(gè)靜態(tài)成員變量：盒子的個(gè)數(shù)number；具有以下成員函數(shù)：1）構(gòu)造函數(shù)和析構(gòu)函數(shù)；2）計(jì)算盒子體積的函數(shù)；3）計(jì)算盒子的表面積的函數(shù)；4）顯示長(zhǎng)、寬、高、體積和表面積的函數(shù)；5）顯示盒子個(gè)數(shù)的靜態(tài)成員函數(shù)。編寫main函數(shù)進(jìn)行測(cè)試。解答：程序編寫：#includeusingnamespacestd;classBox{private:intlength,with,high;staticintnumber;public:Box(intL,i

2、ntW,intH){length=L;with=W;high=H;number++;}~Box(){}intgetLength(){returnlength;}intgetWith(){returnwith;}intgetHigh(){returnhigh;}staticintgetNumber(){returnnumber;}inttiji();intmianji();};intBox::tiji(){intT=length*with*high;returnT;}intBox::mianji(){intM=2*(length*with+length*high+

3、with*high);returnM;}intBox::number=0;voidmain(){Boxb1(2,5,10);Boxb2(4,5,10);cout<<"長(zhǎng):"<

4、b2.getLength()<

5、，增加high成員；派生出汽車類Car，增加seatnum（座位數(shù)）成員。每一個(gè)類都有：各自的構(gòu)造函數(shù)、設(shè)置（如setSpeed等）和返回每個(gè)成員變量（如getSpeed等）的函數(shù)、顯示名稱和參數(shù)的函數(shù)。編寫main函數(shù)進(jìn)行測(cè)試。解答：程序編寫：#includeusingnamespacestd;classVehicle{private:intspeed,weight;public:Vehicle(ints,intw){speed=s;weight=w;}voidsetSpeed(ints){speed=s;}voidsetWeight(in

6、tw){weight=w;}intgetSpeed(){returnspeed;}intgetWeight(){returnweight;}voiddisplay(){cout<<"速度:"<

7、y();cout<<"高度:"<
