#include <iostream> #include <cstring>using namespace Std;class a{private:    char *a;public:    A (char *AA)    {        a = new Char[strlen (AA) +1];  //

        strcpy (A, AA);  //

    }    ~a ()    {        delete []a;   //

    }    void Output ()    {        cout<<a<<endl;    }}; int main () {    A A ("Good Morning, Code monkeys!");    A.output ();    A B ("Good Afternoon, codes!");    B.output ();    return 0;}

(3) To add a copy constructor for Class A, test with the following main function

int main () {    A A ("Good Morning, Code monkeys!");    A.output ();    A B (a);    B.output ();    return 0;}

#include <iostream> #include <cstring>using namespace Std;class a{private:    char *a;public:    A (char *AA)    {        a = new Char[strlen (AA) +1];        strcpy (A,AA);    }    A (a &b)    {        a = new Char[strlen (B.A) +1];        strcpy (A,B.A);    }    ~a ()    {        delete []a;    }    void output ()    {        cout<<a<<endl;    }}; int main () {    A A ("Good Morning, Code monkeys!");    A.output ();    A B (a);    B.output ();    return 0;}
