OOPs stands for Object-Oriented Programming. It is a programming paradigm that uses objects to design applications.

Encapsulation hides the implementation details of an object from the ...
A pointer in C is a variable that stores the memory address of another variable.
Pointers are used to manipulate data directly in memory.
They can be used to pass values by reference to functions.
Example: int *ptr; ptr = # *ptr = 10; //num now has a value of 10
Null pointers are used to indicate that a pointer does not point to a valid memory address.
A list is a collection of items that are ordered and can be accessed by their index.
Lists are mutable, meaning their contents can be changed.
Lists can contain elements of different data types.
Lists are created using square brackets [] and elements are separated by commas.
Example: my_list = [1, 'apple', True, 3.14]
OOP concepts are fundamental principles in programming that promote code reusability and organization through objects and classes.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism where a new class derives properties and behavior from an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to present the ...
