错误信息显示少一个}或者是多一个{下面就OK了#include #includeclass CRectangle { private:double x;double y;double a;double b; public:CRectangle(){ cout<<"\nCRectangle Constructed."<<endl;}CRectangle(double dx, double dy, double da, double db){ x=dx; y=dy; //**1** a=da; b=db; cout<<"\nCRectangle Constructed."<<endl;}~CRectangle(){ cout<<"CRectangle Destructed."<<endl;}void putxy(double dx, double dy){ x=dx; y=dy;}void putab(double da, double db){ a=da; b=db;}double getx(){ return x;}double gety(){ return y;}double geta(){ return a;}double getb(){ return b;}double getperimeter(){ return 2*(a+b);}
