Pointers are variables that store memory addresses. They are used to manipulate data structures and improve program efficiency.
Pointers allow for dynamic memory allocation
Pointers can be used to pass values by reference
Pointers can be used to create linked lists
Pointers can be used to access array elements
Example: int *ptr = # // stores address of num variable
Example: void swap(int *x, int *y) { int temp = *x; *x =...
Arrays are fixed in size and contiguous memory while linked lists are dynamic and non-contiguous.
Arrays have constant time access to elements while linked lists require traversal.
Arrays are better for random access while linked lists are better for insertion and deletion.
Arrays use less memory overhead than linked lists.
Example: Array of strings - ['apple', 'banana', 'orange']
Variables are containers that store data values. There are different types of variables in programming.
Variables are declared using keywords like var, let, const.
Variables can store different types of data such as numbers, strings, booleans, objects, arrays, etc.
Variables can be global or local depending on where they are declared.
Variables can be reassigned with new values.
Examples: var age = 25; let name = 'John'; co

A constructor is a special method that is used to initialize objects of a class.
Constructors have the same name as the class they belong to.
They are called automatically when an object is created.
They can be used to set initial values for object properties.
Constructors can be overloaded to accept different parameters.
Example: public class Car { public Car() { // constructor code here } }
Multiple inheritance cannot be achieved directly in Java, but it can be simulated using interfaces or abstract classes.
Java does not support multiple inheritance of classes
Multiple inheritance can be achieved using interfaces or abstract classes
Interfaces allow a class to inherit from multiple interfaces
Abstract classes can provide partial implementation and can be extended by a single class
