Q1. What is oops?describe
Ans. 
OOPs (Object-Oriented Programming) is a programming paradigm that uses objects to represent and manipulate data.
• OOPs focuses on creating reusable code by organizing data and behavior into objects.

• It provides concepts like encapsulation, inheritance, and polymorphism.

• Encapsulation hides the internal details of an object and provides a public interface.

• Inheritance allows creating new classes based on existing ones, inher...read more

Q2. 4 Pillars of oops
Ans. 
Encapsulation, Inheritance, Polymorphism, Abstraction are the 4 pillars of OOPs
• Encapsulation: Bundling data and methods that operate on the data into a single unit

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

• Polymorphism: Ability to present the same interface for different data types

• Abstraction: Hiding the complex implementation details and showing only the necessary features

Q1. What is array?? Detail in programming
Ans. 
An array is a collection of similar data types stored in contiguous memory locations.
• Arrays can be one-dimensional or multi-dimensional

• Elements in an array can be accessed using their index

• Arrays can be initialized during declaration or later in the code

• Arrays can be passed as arguments to functions

• Example: int arr[5] = {1, 2, 3, 4, 5};

• Example: char str[10] = "Hello";

Q1. What are pointers in c?
Ans. 
Pointers are variables that store memory addresses of other variables in C programming language.
• Pointers are used to manipulate data structures like arrays, linked lists, and trees.

• They can be used to pass values by reference to functions.

• Pointers can also be used to allocate memory dynamically using functions like malloc() and calloc().

Q2. Write a linked list program.
Ans. 
A linked list program is a data structure that stores a sequence of elements with pointers to the next element.
• Create a Node class with a value and a next pointer

• Create a LinkedList class with a head pointer and methods to add, remove, and traverse nodes

• Example: LinkedList ll = new LinkedList(); ll.add(5); ll.add(10); ll.remove(5);
