OOPs stands for Object-Oriented Programming. It is a programming paradigm based on the concept of objects.

• OOPs pillars: Inheritance, Encapsulation, Polymorphism, Abstraction

• Polymorphism: Ability of an object to take on many forms. Types - Compile-time (method overloading) and Runtime (method overriding)

• Inheritance: Ability of a class to inherit properties and behavior from another class

• Encapsulation: Bundling of data and methods that operate on the data into a single unit

• Abst...read more

Structure padding is the insertion of unused bytes between structure members to align them on memory boundaries.

• Padding is added to ensure that each member of a structure starts at a memory address that is a multiple of its size.

• Padding is compiler-dependent and can vary between different platforms and architectures.

• Padding can affect the size of a structure and the performance of the program.

• Example: struct example { char a; int b; char c; }; - padding will be added between ...read more

Forming a dictionary from name

Code to reverse a string using array of characters

• Create an array of characters from the input string

• Iterate through the array in reverse order and append each character to a new string

• Return the reversed string

Polymorphism is the ability of a single function or method to operate on different types of data.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.
