OOSD
Introduction
Object Oriented Programming
- Uses objects in programming
- Implements real world entities like inheritence, hiding, polymorphism, etc.
- Aim of OOPs: Bind together data and functions that operate on them so that no other part of code can access this data except that function
Class
- Building block of C++ that leads to OOPs
- User defined data type
- holds its own data members and member functions accessible through an instance of that class
- Like a blueprint for an object
// Class Example
class person {
// Private Members
// Data Members
string name;
int id;
// Public Members
public:
// Functions
void setDetails () {
name = "Faisal";
id = 1;
}
void getdetails(){
cout << "Name: " << name << endl;
cout << "ID: " << id << endl;
}
};
Object
int main() {
person p1; // p1 is a object
p1.setDetails();
p1.getdetails();
return 0;
}
