6. Overview
• Introduction
• Class
• Object
• Encapsulation
• Abstraction
• Inheritance
• Polymorphism

7. Introduction
• OOP is a design philosophy
• Stands for Object Oriented Programing

8. Object
• Any thing that really exist in the world
• a table, a car, a dog, a person, etc.
• It has some properties
• It has some action

9. class
• Classes provide the structure for objects
• It is a blue print
• It does not exist physically

10. Encapsulation
• The Wrapping of data and function into a
single unit
• It is also known as information-hiding
• It is the way of implementing abstraction

11. example
Class A
{
Int a;
Public int get()
{Return a;}
Public void set()
{a=10;}
}

12. Abstraction
• Data abstraction refers to, providing only essential
information to the user.
• Hide unnecessary data from the user.
class Bank
{
private int accno;
private String name;
private float Balance;

13. Abstraction contd.
private float Profit;
private float Loan;
public void display_to_clerk()
{
cout<<accountno<<Name<<Balnce)
}
Public void display()
{//display all }
}

14. Inheritance
• Mechanism of deriving a new class from an already
existing class.
• 5 types of inheritance
– Single level
– Multilevel
– Multiple Hierarchical
– Hybrid

15. Inheritance cont.

16. Inheritance contd.

17. Polymorphism
• `one name, multiple forms

18. Function Overloading
• Two or more function with same name but different
function
• Differentiated by signature
Class sample
{
Void add(int a,int b)
{
cout<<a+b;
}
Void add(int a,int b,int c)
{
cout<<a+b+c;}
}

19. Example contd.
Int main()
{
Sample s;
S.add(5,10);
S.add(5,10,15);
}
Output
15
30

20. Program using class
class Student
{
public:
char Dob[15];
int marks[5];
int age;
int rollNo;
float avg;
char Name[19];
int total=0;
void setdata()
{
cout<<"nRollNo: ";
cin>>rollNo;
cout<<"n Name:";
cin>>Name;
cout<<"nDOb";
cin>>Dob;
cout<<"Age";
cin>>age;

21. for(int i=0;i<5;i++)
{
cout<<"mark"<<i+1<<": ";
cin>>marks[i];
total=total+marks[i];
cout<<"n";
}
avg=total/5.0;
}
void display()
{
cout<<" "<<rollNo<<" "<<Name<<" "<<age<<"
";
cout<<total<<" "<<avg<<"n";
}};

22. int main()
{
Student s[10];
int n;
cout<<"enter no.of student: ";
cin>>n;
for(int i=0;i<n;i++)
{
cout<<"nenter details of student: "<<i+1;
s[i].setdata();
}
cout<<"n********************************* nn";
cout<<"nRollno Name Age Totalmark AverageMarkn";
for(int i=0;i<n;i++)
{
s[i].display();
}}
