C++ programming language part: 54 Scope Resolution with Overridden Members
Scope Resolution with Overridden Members
To access a base class member from a derived class, the scope
resulation operator is used. Attentively
follow the following program.
Program 42_3
//Scope resulation with
overidden
class furniture //class
defined
{
private:
char color[10];
int width,height;
public:
void data_in()
{
cout<<"Type color of bookshelf
(red or blue?)\t";
cin>>color;
cout<<"Type width\t";
cin>>width;
cout<<"Type height\t";
cin>>height;
}
void data_out()
{
cout<<" The color is
"<
cout<<" The width is
"<
cout<<" The height is
"<
}
};
class bookshelf:public furniture
{
private:
int self_no; // member data
public:
void data_in()
{
furniture::data_in(); //
Scope Resolution Operator
cout<<"Type number of selves\t";
cin>>self_no;
}
void data_out() //member function
{
furniture::data_out(); //
Scope Resolution Operator
cout<<" Number of selves are
"<
}
};
class chair:public furniture
{
private:
int leg_no;
public:
void data_in() //member
function
{
furniture::data_in(); //
Scope Resolution Operator
cout<<"Type number of legs\t";
cin>>leg_no;
}
void data_out() //member function
{
furniture::data_out(); //
Scope Resolution Operator
cout<<" Number of legs are "<
}
};
void
main()
{
bookshelf A;
// A,B is called object
chair B;
A.data_in(); //would
be k->data_in() if pointer
A.data_out();
B.data_in(); //would
be k->data_in() if pointer
B.data_out();
}
