C++

16 lessons — from the very basics to pro-level patterns.

Basics

0. Why Learn C++?

Game engines, browsers, and trading systems — when performance is everything

1. Variables & Data Types

auto, int, string — C with guardrails and type inference

2. Operators & Expressions

Arithmetic, logic, and the << you already know from cout

3. Input & Output

cin, cout, and getline — streams instead of format strings

4. Conditionals

if, switch, and the modern if-with-initializer

for, range-based for, while — classic and modern styles

Collections

6. Arrays & Vectors

Raw arrays vs std::vector — why vectors almost always win

std::string — no more null terminators, just .size() and .substr()

Functions

Overloading, default args, and pass-by-reference with &

Object-Oriented Programming

9. Classes & Objects

Constructors, access modifiers, and this->

10. Inheritance & Polymorphism

virtual, override, and why the destructor should be virtual

Memory Management

11. Pointers & References

Raw pointers, & references, and when to use which

12. Smart Pointers

unique_ptr, shared_ptr — let RAII handle your cleanup

Standard Template Library

13. STL Containers

map, set, unordered_map, deque — the C++ toolbox

14. Iterators & Algorithms

sort, find, transform — STL algorithms that replace hand-written loops

Advanced

Write once, use with any type — generic programming in C++
