Source Files

In C++ development, especially when using Visual Studio Code (VS Code), the tasks.json file plays a crucial role in automating the build process.

If you're writing pure C++ code, using .hpp can make your intent clearer.

If you're working in a mixed C/C++ environment, .h might be more compatible.

In Visual Studio Code (VS Code), the .hpp file extension is used for C++ header files

#pragma once is a preprocessor directive in C++ that ensures a header file is included only once during compilation.

In C++, the #ifndef and #define directives are part of include guards, which prevent a header file from being included multiple times during compilation. This is crucial for avoiding redefinition errors.

In C++, a macro name is an identifier used with preprocessor directives like #define, #ifdef, and #ifndef.

#endif is a preprocessor directive in C++ that marks the end of a conditional block started by #if, #ifdef, or #ifndef. It's most commonly used in include guards to prevent multiple inclusions of a header file

In C++, public function prototypes refer to the declarations of member functions that are accessible from outside the class. These are typically placed in the public section of a class definition, often inside a header file (.hpp or .h)

In C++, private data member declarations are used to define variables inside a class that are not accessible directly from outside the class. This is a key part of encapsulation, one of the core principles of object-oriented programming.

The scope resolution operator in C++ is written as :: and is used to access identifiers (like variables, functions, or classes) that are defined in a specific scope—such as a namespace or class.
