Using a copy constructor in C++ creates a new object by copying the values of another object.
Copy constructor is a special member function that creates a new object as a copy of an existing object.

Pointers/references are used to pass memory addresses instead of values, for efficiency and to modify data directly.
Use pointers when you need to modify the original data passed to a function
Use references when you want to avoid copying large data structures
Pointers are commonly used in dynamic memory allocation
References are used in function parameters to avoid unnecessary copying
Example: int x = 10; int *ptr = &x; *p

Inheritance: creating new classes from existing ones
Abstraction: hiding implementation details and showing only the necessary information
Polymorphism: using ...
Encapsulation in Java is achieved by using access modifiers and creating classes with private fields and public methods.

The pillars of OOPS are Inheritance, Encapsulation, Abstraction, and Polymorphism.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation restricts access to certain components within a class, protecting the data from outside interference.
Abstraction hides the complex implementation details and only shows the necessary features to the user.
Polymorphism allows objects to be treated...
