Difference between array and linked list. What is deadlock?Describe OOP.

Question

Accepted Answer

Array and linked list are data structures. Deadlock is a situation where two or more processes are unable to proceed. OOP is a programming paradigm.

Array is a collection of elements of the same data type stored in contiguous memory locations.
Linked list is a collection of elements called nodes, where each node contains a data field and a reference to the next node.
Deadlock occurs when two or more processes are waiting for each other to release resources, resulting in a standstill.
OOP is a programming paradigm that focuses on objects and their interactions, encapsulation, inheritance, and polymorphism.
Example of array: int arr[5] = {1, 2, 3, 4, 5};
Example of linked list: struct Node { int data; struct Node* next; };
Example of deadlock: Process A holds resource X and waits for resource Y, while process B holds resource Y and waits for resource X.
Example of OOP: class Car { private: string make; int year; public: void start() { // code to start the car } };
