谁有网页制作的视频教程啊，打包的，发给我呗，谢谢！！！！！
急急急 拷贝构造函数谁能讲讲吗，有点不太明白
求大神门调调，谢谢各位大神啦 #include"iostream.h" template<class T> class circle { protected: T r; public: circle(T x=0.0) { r=x; } virtual void area()const { cout<<"圆的面积为:"<<3.14*r*r<<endl; } }; template<class T,class T1> class cylinder:public circle<T> { protected: T1 h; public: cylinder(T x=0.0,T1 y=0.0):circle<T>(x) { h=y; } void area()const { cout<<"圆柱体的面积为:"<<2*3.14*r*r+3.14*r*h<<endl; } }; int main(void) { circle<double> c1(2.1),*p; cylinder<double,int> c2(2.1,6); c1.area(); c2.area(); cout<<"_______________________________"<<endl; p=&c1; p->area(); p=&c2; p->area(); }
大神们帮帮 #include"iostream.h" class complex { protected: double real; double image; public: complex(double rp=0,double ip=0):real(rp),image(ip) {} void print(void)const; friend complex operator+(const complex &y); friend complex operator-(const complex &y); friend complex operator*(const complex &y); friend complex operator/(const complex &y); }; void complex::print(void) const { cout<<"("<<real<<","<<image<<"i)"<<endl; }; inline complex operator +(const complex &x,const complex &y)const { return complex(x.real+y.real,x.image+y.image); } inline complex operator -(const complex &x,const complex &y)const { return complex(x.real-y.real,x.image-y.image); } inline complex operator *(const complex &x,const complex &y)const { return complex(x.real*y.real-x.image*y.image,x.real*y.image+x.image*y.real); } inline complex operator /(const complex &x,const complex &y)const { double m; m=y.real*y.real+y.image*y.image; return complex((x.real*y.real+x.image*y.image)/m, (x.image *y.real-x.real *y.image)/m); } void main(void) { complex a(9,2),b(7,3),c; c=a+b*a/b-b; c.print(); }
