第六周阅读程序五

#include <iostream>using namespace std;class AA{public:    AA(int i,int j)    {        A=i;        B=j;        cout<<"Constructor\n";    }    AA(AA &obj)    {        A=obj.A+1;        B=obj.B+2;        cout<<"Copy_Constructor\n";    }    ~AA()    {        cout<<"Destructor\n";    }    void print()    {        cout<<"A="<<A<<",B="<<B<<endl;    }private:    int A,B;};int main(){    AA a1(2,3);    AA a2(a1);    a2.print();    AA *pa=new AA(5,6);    pa->print();    delete pa;    return 0;}

预计结果：Constructor

                    Copy_Constructor

                    A=3,B=5

                    Constructor

                    A=5,B=6

                    Destructor

                    Destructor

                    Destructor
