1. Single Inheritance
A class inherits its property to another class then such type of inheritance known as single inheritance.
In the above diagram class B is derived class A. Therefore object of class B can access the public property of derived class B as well as its own.
e.g: Program for single level inheritance#include<conio.h>
#include<iostream.h>
class Employee{
protected:
int eno;
public:
Employee()
{
cout<<"\nEnter Emp No ";
cin>>eno;
}
};
class Manager:public Employee{
public:
void showgrade(){
cout<<"\n Employee no : "<<eno;
cout<<"\n Grade : n";
}
};
void main()
{
Manager m;
clrscr();
m.showgrade();
getch();
}
O/P
Employee no : 101 Grade :n
