Question

Accepted Answer

C++ core concepts include OOP principles, memory management, operator overloading, and features of the QT framework.

Object-Oriented Programming (OOP): C++ supports encapsulation, inheritance, and polymorphism.
Copy Constructor: A special constructor used to create a new object as a copy of an existing object. Example: `ClassName(const ClassName &obj)`.
Operator Overloading: Allows custom implementation of operators for user-defined types. Example: `bool operator==(const ClassName &obj)`.
Memory Management: C++ uses manual memory management with `new` and `delete`. Example: `int* ptr = new int; delete ptr;`.
QT Framework: A cross-platform application framework that provides tools for GUI development, event handling, and more.
