Single inheritance allows a subclass to inherit properties from a single parent class. The parent class is known as the base class while the subclass is known as the derived class. An example program demonstrates single inheritance by defining a base class "first" with integer properties "a" and "b", and a derived class "second" that inherits from "first" and adds an integer property "c". The program gets user input for "a" and "b", displays their values, and calculates the sum stored in "c".

2. It is the capability of one class to Inherit the properties from another
class which is already exist in the program. The class from which
another class is Derived is known as Base Class or Parent Class &
the class which is derived from the Base Class is known as Sub-
Class or Child Class.

3. Types of Inheritance’s :
Single Inheritance
Multiple Inheritance
Hierarchical Inheritance
Multi-Level Inheritance
Hybrid Inheritance 3

4. Single Level Inheritance

5. In single level inheritance, there is only one base
class and has only one derived class.
Base Class
Derived Class
Here “A” is the Base class & “B” is the Derived class of “A”, i.e. “B” has the similar
properties of that the class “A” consist. 5

6. Example :
class Base
{
};
class Derv: public Base
{
};

7. A sample program to ADD two values using Single Level Inheritance.
#include<iostream>
#include<cstdlib>
using namespace std;
class first //base or parent class
{
public: //Access Specifier
int a,b;
void getdata() //member function getdata()
{
cout<<"nEnter Number : t";
cin>>a>>b;
}
void putdata() //member function putdata()
{
cout<<"nNumbers are : t"<<a<<"t"<<b;
}
};
class second :public first //class second inherits
property of class first
{
public : //Access Specifier
int c;
void add()
{
getdata();
putdata();
c=a+b;
cout<<"nAfter Addition : t"<<c;
}
};
int main()
{
system(“clear”);
second s1; //s1 is object of class second
s1.add();
return 0;
}
7

8. Output
Enter Number : 10 20
Numbers are : 10 20
After Addition : 30
