定义一个矩形类,要求定义成员函数实现:构造长方形.计算长方形的面积.周长,假定长

#include <iostream>using namespace std;class Box {\x09float leng

你好,以下是满足题目要求的示例代码,请参考：#includeusingnamespacestd;classRectangle{private:intwidth,length;public:Rectan

#include#includeusingstd::cout;usingstd::cin;usingstd::endl;usingstd::string;classBook{public:Book(s

classRecangle{private:intwidth;intlength;public:Recangle(){width=0;length=0;};Recangle(intw,inth){wi

classCircle{public:Circle(intnr){r=nr;}Circle(){}public:intr;intArea(){return3.14*r*r;}};classB{publ

可以的,在类内定义的函数被视为内联函数.在类内定义一般函数没什么要求,但是定义的是操作符重载的话,就有一定限制了.有些操作符的重载是不能再类内定义的.具体可参阅C++Primer.

Java的行不,C++的不记得了.publicclassCircle{privatestaticdoublePI=3.14privatedoubleradius;publicCircle(double

#includeclassCircle{public:Circle():radius(0){}Circle(doubler):radius(r){}constdoublearea()co

以下程序,直接拿去交作业吧,都测试过了.//圆周长面积#include#definepi3.14159classcircle{public:voidsetRadius(){std::cout

publicclassStudent{Stringname,id;intage,english,math,chinese;Student(inta,intb,intc,intd,Stringe,Str

classTriangle{private:\x05doublea;\x05doubleb;\x05doublec;public:\x05Triangle():a(0),b(0),c(0){}\x05

classComplex{public:Complex(){real=0;imag=0;}//定义结构函数Complex(doubler,doublei){real=r;imag=i;}//构造函数重

#includeusingnamespacestd;classClock{public:Clock(inth=0,intm=0,ints=0):hour(h),minute(m),second(s){

把这三个类分别放到三个.java文件中,然后编译运行即可.publicclassCircle{privatedoubler;publicCircle(doubler){this.r=r;}public

classCat{privateintnumofcats;publicintgetnumofcats(){returnnumofcats;}}

代码写好了,我发给你

classCRect{public:CRect(intx,inty,intWidth,intHeight);voidSetSize(intWidth,intHeight);voidSetPos(int

classcs{publicint_w;publicint_h;puliccs(intw,inth){_w=w;_h=h;}publicintmj(){return_w*_h;}publicintzc
