🔤 A–Z of Programming 💻

A – Array
A data structure that stores a collection of elements of the same type, accessed by index.

B – Binary
A base-2 number system using 0s and 1s, the foundation of how computers represent data and perform operations.

C – Class
A blueprint in object-oriented programming for creating objects, defining attributes and methods.

D – Data Structure
An organization of data for efficient access and modification, like lists or trees.

E – Exception
An error or unexpected event during program execution that can be handled to prevent crashes.

F – Function
A reusable block of code that performs a specific task, often taking inputs and returning outputs.

G – Git
A version control system for tracking changes in code, enabling collaboration and history management.

H – HashMap/Hash Table
A data structure storing key-value pairs for fast lookups using hashing.

I – Inheritance
A mechanism where a class inherits properties and methods from a parent class in OOP.

J – JavaScript
A versatile language for web development, handling client-side interactivity and server-side with Node.js.

K – Keyword
A reserved word in a language with special meaning, like "if" or "for", not usable as variable names.

L – Loop
A control structure repeating code until a condition is met, such as for or while loops.

M – Modulus
An operator (%) returning the remainder of division, useful for cycles or checks.

N – Null
A special value indicating absence of data or no object reference.

O – Object
An instance of a class containing data (attributes) and behavior (methods) in OOP.

P – Pointer
A variable storing the memory address of another variable for direct access.

Q – Queue
A FIFO (First-In-First-Out) data structure for processing items in order.

R – Recursion
A function calling itself to solve smaller instances of a problem.

S – Stack
A LIFO (Last-In-First-Out) data structure, like a stack of plates.

T – Testing
Verifying a program's correctness through unit tests, integration, and more.

U – Unicode
A standard encoding characters from all writing systems for global text handling.

V – Variable
A named storage for data that can change during program execution.

W – While Loop
Repeats code while a condition remains true, offering flexible iteration.

X – XOR
A logical operator true if operands differ, used in cryptography and checks.

Y – Yield
A keyword returning a value from a generator, enabling lazy iteration.

Z – Zeroes (numpy.zeros)
Creates an array filled with zeros, useful for initialization.
