Question

定义一个复数类，其属性为复数的实部和虚部

要求定义和使用构造函数和拷贝构造函数，并定义成员函数显示复数的值
注：不要复制百度的给我，谢谢

Answer 1

#include "string.h"
#include "iostream.h"
class complex
{ private:
float x,y;
public:
complex(float x, float y)
{ this->x=x; this->y=y;
cout<<"通过构造函数创建对象"<<x<<"+"<<y<<"i"<<endl;
}
void set(float x1,float y1) { x=x1; y=y1;}
void show( );
~complex( ) {cout<<"析构函数释放对象"<<x<<"+"<<y<<"i"<<endl;}
friend double add1(complex t1,complex t2);
friend double add2(complex t1,complex t2);
};
double add1(complex t1,complex t2)
{ return t1.x+t2.x; }
double add2(complex t1,complex t2)
{ return t1.y+t2.y; }

void complex::show( )
{cout<<"此复数是："<<x<<"+"<<y<<"i"<<endl;}
void main( )
{
complex t1(1.0,2.0),t2(3.0,4.0);
cout<<"两个复数的和: "<<add1(t1,t2)<<"+"<<add2(t1,t2)<<"i"<<endl;
}
