Vigenère Cipher in C++: How It Works, and How to Break It
Three centuries as the indecipherable cipher, and 1.6 milliseconds to break. Working C++ for both directions, plus the attack that recovers the key.
C++ Programming Tutorials — Fundamentals to Advanced Techniques
C++ is one of the most powerful and widely used programming languages in the world. Built on the foundation of C, it adds object-oriented programming, generic programming through templates, and the rich Standard Template Library — making it the language of choice for game development, systems programming, high-frequency trading, real-time applications, and performance-critical software.
MYCPLUS has been one of the web’s longest-running C++ programming resources, publishing tutorials, source code examples and practical guides since 2004. This section covers everything from the absolute basics of C++ syntax through to modern C++ features introduced in C++11, C++14, C++17 and beyond. You will find clear explanations of classes, inheritance, polymorphism and encapsulation, practical STL container and algorithm examples, and real-world source code that demonstrates how C++ is used in professional software development.
Whether you are a student learning C++ for the first time, a C programmer making the transition to object-oriented development, or an experienced developer exploring modern C++ features like smart pointers, move semantics and lambda expressions — this section has the resources you need to level up your C++ skills.
What You’ll Learn:
- C++ fundamentals — classes, objects, constructors, destructors, access modifiers and the core OOP model
- Inheritance and polymorphism — class hierarchies, virtual functions, abstract classes and runtime polymorphism
- STL mastery — vectors, maps, sets, iterators and the standard algorithms library with practical examples
- Modern C++ features — smart pointers, move semantics, lambda expressions, auto typing and range-based loops
- Templates and generic programming — function templates, class templates and template specialisation
- Game development with C++ — how C++ powers game engines, graphics programming and real-time systems
Why MYCPLUS: One of the web’s longest-running C++ resources — trusted since 2004 with hundreds of tutorials, examples and source code projects built for real learning.
C++ Hello World Program — Your First Program, Explained Line by Line
Four lines, one line of output, and more going on underneath than any tutorial admits. A tested walkthrough from source file to running binary.
typedef vs using in C++: Type Aliases and Alias Templates
Two keywords, one difference that matters — and it is the one short explanations skip. Tested examples, captured errors, and when to use each.
Microsoft C++ REST SDK Is Archived: What to Use Instead
Archived on 1 June 2026, read-only, 797 issues frozen. It still compiles clean on GCC and fails outright on current MSVC. Here is what to do about it.
STL Containers in C++: How to Choose the Right One
The complexity table says list wins. Measured, vector was 30 times faster with the same search. A selection guide for the C++ container library.
Pointers in C++ — From Raw Pointers to Smart Pointers (Complete Tutorial)
A unique_ptr is 8 bytes — exactly the same as a raw pointer. Pointers from declaration to ownership, with every claim compiled and measured.
Virtual Functions in C++ — vtables, Pure Virtual Functions, and Abstract Classes
One virtual function grew a class from 4 bytes to 16. Three kept it at 16. What vtables cost, measured, plus the destructor rule nobody mentions.
