C++ guide: design patterns, SOLID and best practices

C++ overview

Zero-cost abstractions and full control over memory. Every language page follows the same structure, so you can jump between languages and compare.

This guide covers modern C++. Its source repository is named training-algorithms-c, but the code in it is C++.

Hello world

hello.cpp

#include <iostream>

int main() {
    std::cout << "Hello, patterns!\n";
}
