1、 2. 第二题改了一下题注意： 2. 第二题改了一下题注意： 1. 第五行21920 xi=temp;*a =3. 在return01. 第五行21920 xi=temp;*a =3. 在return0前加一句 delete height10; 改为constheight = 函数如类成Box,(); /改动了，因为输出类本身的信息，就去掉参voidpr constheight=/增加const量不len) width= lengthBox,(); /改动了，因为输出类本身的信息，就去掉参voidpr constheight=/增加const量不len) width= length= b) B

2、ox a(15, 20),b(20, (); /函数加括returnusing Goods num,floatvoid num,price)this-numusing Goods num,floatvoid num,price)this-num = this-price= void coutid =voidputname(stringname)this-name=name;void ost(floatcost) this-cost = cost;MaxSchool private: MaxSchool(stringfilename); void getMaxSchool();MaxSchool

3、:MaxSchool(string ifstream float cost;while(infileidcost)Schoolsch; /coutidnamecostendl; MaxSchool:getMaxSchool() ntmaxVal1; maxIndex=0; i=0; i maxVal)maxValMaxSchool:getMaxSchool() ntmaxVal1; maxIndex=0; i=0; i maxVal)maxVal=curCost; maxIndex = i;/输出信coutschoolsmaxIndex.getid()schoolsmaxIndex.getna

4、me() schoolsmaxIndex.getcost() r=virtualvoid coutheight= h; this-width =w;virtual Area()double width; doubleheight;classTriangle:double classRectangle(doublew,double h) this-height= h; this-width =w;virtual Area()double width; doubleheight;classTriangle:Triangle(doublea,doub c) this-a = a; this-b = b;this-c= ,virtualvoid doubles(a+b+c)/2;/先算出周长的一s = s*(s-a)*(s-b)*(s-couts
