Variable: A named storage location in memory for holding data.

Data Type: Specifies the type of data a variable can hold (e.g., int, float, char).

Function: A block of code that performs a specific task.

Statement: A single line of code that performs an action.

Loop: A control structure that repeatedly executes a block of code.

Array: A collection of elements of the same data type stored under one variable name.

If Statement: Conditional statement that executes code based on a condition.

Operator: A symbol or keyword used to perform operations (e.g., +, -, *, /).

Pointer: A variable that stores the memory address of another variable.

Class: A blueprint for creating objects, encapsulating data and functions.

Object: An instance of a class, with its own data and behavior.

Inheritance: A mechanism for creating a new class based on an existing class.

Polymorphism: The ability of objects to take on multiple forms, typically achieved through function overloading and virtual functions.

Template: A feature allowing the creation of generic data types or functions.

Exception Handling: A mechanism for dealing with runtime errors. 

STL (Standard Template Library): A collection of C++ template classes for common data structures and algorithms.

Lambda Expression: An anonymous function used for concise code and functional programming.

RAII (Resource Acquisition Is Initialization): A C++ programming idiom for managing resources like memory and file handles.

Move Semantics: A feature allowing the efficient transfer of resources between objects.

Smart Pointer: A class for automatic memory management, such as std::shared_ptr and std::unique_ptr.

Concurrency: Dealing with parallel execution, often involving threads and mutexes.

Design Patterns: Reusable solutions to common programming problems.

Operator Overloading: Defining custom behaviors for C++ operators in user-defined classes.

CRTP (Curiously Recurring Template Pattern): A template metaprogramming technique used to implement static polymorphism.

SFINAE (Substitution Failure Is Not An Error): A principle in template metaprogramming that allows for graceful handling of substitution failures.
