Cpp Archive

A personal archive of C++ code snippets, algorithms, and utility programs.

Overview

This repository serves as a collection of reusable C++ code, including:

• Common algorithms and data structures
• Utility classes and functions
• Example programs and problem solutions
• Templates for common C++ patterns

The purpose is to provide a handy reference for C++ development and to encourage code reuse across projects.

Features

• 100% C++ code
• Well-organized by topic and type
• Self-contained snippets for easy copy-paste
• Includes comments and usage examples where appropriate

Header Files

Descriptions for files in the header directory (browse all headers):

• typedef.h
  Provides type aliases for fixed-width integers (i8, u16, etc.), floating-point types (f32, f64), and optionally 128-bit types if supported, to simplify type usage across code.

• containerlib
  Utilities for working with STL containers. Includes type traits to detect vectors, conversion utilities, and functions to parse strings into vectors (including nested vectors).

• enum_helper
  Macros and templates for working with enums, including range checks, flag checks, casting, and bitwise operator overloads to make enums easier to use as bitfields or flag sets.

• fdstream
  Defines ifdstream and ofdstream: C++ input/output stream wrappers for file descriptors, allowing use of standard streams with POSIX file descriptors (useful for advanced I/O and IPC).

• function_traits
  Introspection utilities for std::function types, enabling you to extract argument and return types, and the number of arguments, for generic programming.

• ipc
  An experimental header for process management and inter-process communication. Defines Pipe, ProcessStartInfo, and a Process class for launching and managing external processes, with support for I/O redirection.

• range
  Provides a compile-time range class template, allowing you to easily iterate over integer ranges using C++ range-based for loops, similar to Python's range().

• streamlib
  Utilities for stream manipulation, such as ignoring values of specific types or using custom initializers when reading from streams. Useful for flexible and generic input parsing.

• strlib
  Utilities for string manipulation: joining, splitting, trimming, padding, case conversion, and character checks. Includes both modern and deprecated split/join methods for containers and algorithms.

• threadlib
  Utilities for asynchronous programming and event handling. Provides an event class template with synchronous and asynchronous policies, handler registration/removal, and a timer class for periodic events (since C++20).
