使用VC6打开考生文件夹下的工程test1_1,此工程包含一个源程序文件test1_1.cpp,但该程序运行有问题,请改正main函数中的错误,使该程序的输出结果如下: Constructor called. Default constructor called. Area is 6 Area is 0 Area is 6 源程序文件test1_1,cpp清单如下: #include<iostream.h> class RectAngle
private: double ledge,sedge; public: RectAngle()
cout<<"Default constructor called.";
RectAngle(double l,double s)
ledge=l;sedge=s; cout<<"Constructor called.";
void Set(double l,double s)
ledge=l;sedge=s;
void Area()
cout<<"Area is"<<ledge*sedge<<endl;
; void main()
/***************** found *****************/ RectAngle Rect1(2,3); RectAngle Rect2(1); /**************** found *****************/ RectAnglC Rect3; Rectl.Area(); /***************** found *****************/ RecL2.lodge=0;Rect2.sedge=0; Reck2.Area(); Rect3.Area();
