C++ Tutorial

Introduction

If you’re searching for a C++ tutorial, you’ve likely come across multiple versions of the language—C++98, C++11, and what many now call Modern C++. For newcomers and even seasoned developers, understanding these versions can be overwhelming. What do these names mean? How do they impact your learning experience? And which version should you focus on in the best C++ tutorial?

This article will help you make sense of these differences, and guide you toward choosing the right C++ tutorial based on your goals.

C++98: The Legacy Foundation

C++98 (also known as C++03, with minor revisions) was the first standardized version of C++, ratified by the ISO in 1998. This version built upon C and added object-oriented features such as classes, inheritance, encapsulation, and polymorphism. It also introduced key features like:

• Templates
• Operator overloading
• Namespaces
• The Standard Template Library (STL)
• Exception handling

Why It Matters in Tutorials

Early C++ tutorials based on C++98 are often procedural in tone. They focus on building a foundation in object-oriented programming and data structures using low-level constructs. These tutorials are great for understanding the inner workings of C++ and its close ties to C.

However, C++98 tutorials usually lack modern conveniences. For example, they don’t include auto type deduction, range-based loops, or smart pointers, all of which make modern C++ more readable and safer to use.

Best use case: Use C++98-focused tutorials if you want to work on legacy codebases, or understand C++ from the ground up.

C++11: The Game Changer

Ratified in 2011, C++11 is considered one of the most significant updates to the language. It introduced features that drastically improved productivity, performance, and code readability. Some key features of C++11 include:

• auto keyword for type inference
• nullptr instead of NULL
• Range-based for loops
• Lambda expressions
• Smart pointers (shared_ptr, unique_ptr)
• Move semantics
• constexpr functions
• Multithreading support (std::thread)

C++11 made the language more expressive and modern, aligning it better with other high-level programming languages.

Why It Matters in Tutorials

A C++ tutorial that covers C++11 offers a smoother, safer, and more practical programming experience. You write less boilerplate code and gain access to powerful constructs that make programs more maintainable and scalable.

These tutorials often include more real-world scenarios, such as how to handle memory with smart pointers, write cleaner loops, and pass functions as arguments using lambdas.

Best use case: C++11 tutorials are ideal if you’re learning C++ for modern application development, especially in fields like game development, finance, or high-performance computing.

Modern C++: Beyond C++11 (C++14, C++17, C++20 and Beyond)

The term Modern C++ typically refers to the language standards from C++11 onwards, but more often, it implies C++14, C++17, and C++20, each of which built on the improvements introduced in C++11.

Key Features in Modern C++:

• C++14: Relaxed constexpr, generic lambdas, and binary literals
• C++17: std::optional, std::variant, if constexpr, structured bindings, and filesystem library
• C++20: Concepts, ranges, coroutines, modules, and std::format

Modern C++ is cleaner, safer, and more powerful than ever. With support for functional programming paradigms, better compile-time evaluation, and improved standard libraries, Modern C++ is optimized for performance and readability.

Why It Matters in Tutorials

The best C++ tutorial today will focus on Modern C++, showing you how to leverage these features to write robust, maintainable, and scalable code. You’ll find topics like:

• Writing asynchronous code using coroutines
• Using std::optional and std::variant for type safety
• Structuring large projects with modules
• Improving performance with move semantics and perfect forwarding

Best use case: If you’re learning C++ to work in modern software engineering environments or want to future-proof your skills, choose a Modern C++ tutorial.

Comparing the Tutorial Styles

Which C++ Tutorial Should You Choose?

When deciding which C++ tutorial to follow, consider your goals:

• For academic learning or legacy systems → Start with C++98
• For intermediate development and cleaner code → Learn C++11
• For cutting-edge development and real-world applications → Choose a Modern C++ tutorial

The best C++ tutorial is one that aligns with your use case and coding goals, while progressively introducing modern features. Tutorials that show the transition from C++98 to C++20 help you understand the “why” behind new features, not just the “how.”

Conclusion

Understanding the difference between C++98, C++11, and Modern C++ is crucial when picking the right tutorial. While all versions share the same core language, each new standard has introduced tools that make development faster, safer, and more expressive.

If you’re just starting, look for the best C++ tutorial that begins with C++11 or later. These versions represent the modern style of C++ coding and are more aligned with today’s software development standards.

By learning Modern C++, you’ll not only write better code but also prepare yourself for high-performance, industry-grade software development. So, choose wisely—and happy coding!
