C++ Modern C++ Tutorial — Learn Modern C++ in C++

C++ Tutorial: Modern C++

C++11/14/17/20 features — move semantics, rvalue references, auto, range-for, structured bindings, if constexpr, concepts, and more.

C++: modernised

C++ has evolved dramatically since C++11. Move semantics eliminate unnecessary copies. `auto` reduces verbosity. Structured bindings unpack tuples naturally. Concepts (C++20) make template error messages readable.

These features make modern C++ feel almost like a different language from C++03 — while keeping full backward compatibility.

What you'll learn in this C++ modern c++ tutorial

This interactive C++ tutorial has 6 hands-on exercises. Estimated time: 22 minutes.

Move semantics — steal instead of copy — Copying a vector copies all its elements. **Moving** it transfers ownership — O(1) instead of O(n).
auto and type deduction — `auto` deduces the type from the initialiser. Especially useful for iterators and complex types.
Structured bindings — C++17 structured bindings decompose tuples, pairs, and structs:
std::optional — null safety without nullptr — `std::optional<T>` represents a value that may or may not exist — safer than null pointers:
Initializer lists and uniform initialization — C++11 uniform initialization with `{}` works everywhere:
Build a modern utility library — No starter code.
