The pillars of OOP are encapsulation, inheritance, polymorphism, and abstraction, forming the foundation of object-oriented programming.
Encapsulation: Bundling data and methods that operate on the data within one unit (class). Example: A class 'Car' with attributes like 'color' and methods like 'drive()'.
Inheritance: Mechanism to create a new class using properties of an existing class. Example: 'ElectricCar' inhe...
This C program reverses a given string using an array of characters.

- Q1. Difference between C++ and Java in inheritance
- Ans.
C++ supports multiple inheritance while Java supports single inheritance.
C++ allows a class to inherit from multiple classes, while Java only allows a class to inherit from one class.
Java uses interfaces to achieve multiple inheritance-like behavior.
C++ inheritance is more flexible but can lead to ambiguity and complexity, while Java's single inheritance simplifies the design.
Example: C++ - class B: public A, public C;...
