设计一个复数类,成员变量包括实部和虚部,成员方法包括实现复数加法和减法运算

#include#includeusingnamespacestd;classComplex{floatm_Real;floatm_Image;public:Complex(floatr=0.0,fl

classComplex{public:\x05Complex(doubler,doublei):real(r),imag(i){}\x05voidprint();\x05friendComplexo

classcomplex{intreal;intimg;public:complex(int_real,int_complex&operator+(complex&x){real+=x.real;}}

classscore{privatedoubleenglish;publicvoidsetScore(doubleenglish){this.english=english;}publicvoidpr

例如定义一个类：classText{\x09publicstaticintnumber;\x09publicinttemp;}如果你想访问temp属性,你就必须先创建一个Text的对象,才能访问：Te

classComplex{doublereal;doubleimaginary;public:Complex(double&r=0,double&i=0):real(r),imaginary(i){}

classcomplex{doublex,y;complex(doublea,doubleb){x=a;y=b;}}publicclassshiyan42{publicstaticvoidmain(S

#includeusingnamespacestd;constdoublepi=3.14;//Point类,派生出Rectangle类和Circle类,计算各派生类对象的面积Area（）.templa

你问题说得不全啊,给你个简单的java例子,计算两点间的距离.publicclassPoint{privateintx;privateinty;publicPoint(){x=0;y=0;}publi

classCircle{protecteddoubleradius;publicCircle(){radius=0;}publicCircle(doubleradius){thi

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

C++实现的复数类,代码如下//complex.cpp#includeusingnamespacestd;classcomplex{//复数类public:complex(doubler=0.0,do

classCuboid{friendintVolume(constCuboid&);intlength;intwidth;intheight;};intVolume(constCuboid&c){re

classcircle{floatradius;floatarea;public:circle(floatr){radius=r;}floatgetarea(void){area=3.14*radiu

classcircle{public:circle(){radius=0;}circle(doubleradiuv){radius=radiuv;}voidgetparimeter(){parimet

c++?很容易啦,网上搜一搜就有代码.#includeusingnamespacestd;classComplex{public:Complex(){real=0;imag=0;}Complex(do

#include#includeusingnamespacestd;classPoint//Point类定义{public://外部接口Point(intxx=0,intyy=0){X=xx;Y=yy

想问什么?类指针是指向一个类的指针,比如classA{inta；}；A*p；p是个指向类的指针；要用这个指针访问成员变量,需要建立对象,p=newA（）；p->a=1;deletep;

哦,也就是说在B类中有一个成员变量是一个A类的实例吗.给个例子给你：classB{privateintlength;privateAa;}

publicclassciecle(){intx;inty;intr;}get(intx1,inty1,intr1){x1=x;y1=y;r1=r;}
