1. Single Inheritance
It refers to the process of deriving a class from a single base class. It has only one base and one derived class as shown in figure,
Figure: Single Inheritance
Syntax
class baseclass
{
-----------
};
class Derived : Visibility base
class
{
-----------
}
Example
class Automobile
{
//body
};
class Cars : public Automobiles
{
// body
};
Program
#include<iostream:h>
#include<conio.h>
class B
{
int a;
public:
int b;
void get_ab();
int get_a();
void show_a();
};
class D: private B
{
int c;
public:
void mul();
void display();
};
void B::get_ab()
{
cout<<“Enter Values for a
and b”;
cin>>a>>b;
}
int B::get_a()
{
return a;
}
void B::show_a()
{
cout<<“a=
"<<a<<“\n”;
}
void D::mul()
{
get_ab();
c=b* get_a();
}
void D:: display()
{
show_a();
cout<<“b=
"<<b<<“\n”;
cout<<“c=
"<<c<<“\n\n”;
}
void main()
{
clrscr();
D d;
d.mul();
d.display( );
d.mul();
d.display( );
getch();
}
