C++

A system language balancing high performance and engineering productivity

What problem does this technology solve?

C++ combines low-level control with engineering features like object-oriented programming, generics, and RAII. It's widely used in game engines, high-performance computing, and foundational software. The key learning goal is to move from "getting code to compile" to writing safe, efficient code.

If you're unsure whether to invest time in this, check your target job descriptions first. See how frequently the technology appears and what role it plays in projects, then decide on your learning priority.

C++ Smart Pointers for Resource Management

Use unique_ptr to express exclusive ownership; it is automatically released when the scope ends.

#include <memory>
#include <iostream>
