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.

header and implementation files

Header files contain declarations — they tell the compiler what functions, classes, and variables exist, but not how they work.

Implementation files contain the definitions — the actual code that performs the work declared in the header.

A compiler toolchain in C++ refers to the complete set of tools used to transform source code into executable programs.

Assembly language is a low-level programming language that provides direct control over a computer's hardware. It's one step above machine code and uses mnemonics (human-readable instructions) to represent processor operations.

In C++, an object file is an intermediate binary file generated during the compilation process. It contains machine code and metadata, but it's not executable on its own — it must be linked with other object files and libraries to create a final executable.

hassle: a situation that is annoying because it involves doing something difficult or complicated that needs a lot of effort

In C++, I/O streams (Input/Output streams) are a powerful abstraction for reading and writing data. They are part of the library and allow you to interact with the console, files, and other data sources in a consistent way

In C++, a linker is a crucial tool that combines multiple object files into a single executable or library. It resolves references between functions and variables across different files, ensuring that your program runs as a unified whole.

An IDE (Integrated Development Environment) is a software application that provides comprehensive tools for software development in one place. For C++ programming, IDEs streamline coding, compiling, debugging, and project management.
