Cpp Expert

This is a solid reference for modern C++ that cuts straight to the practical stuff. You get concrete examples of C++20/23 features like concepts, ranges, and coroutines, plus the fundamentals you actually need: smart pointers, move semantics, RAII patterns. The code samples are complete enough to compile and run, which beats hunting through Stack Overflow when you need to remember how to write a proper move constructor or chain range views. It leans heavily on showing rather than explaining, so you'll want some C++ experience already. Best used when you're upgrading legacy code to modern standards or need a quick syntax check on the newer language features without wading through committee proposals.

C++ Expert

Expert guidance for modern C++ development including C++20/23 features, STL, templates, memory management, and high-performance programming.

Core Concepts

Modern C++ Features (C++20/23)

Concepts and constraints
Ranges and views
Coroutines
Modules
Three-way comparison (spaceship operator)
std::format
std::span
Designated initializers
consteval and constinit

Memory Management

RAII (Resource Acquisition Is Initialization)
Smart pointers (unique_ptr, shared_ptr, weak_ptr)
Move semantics and perfect forwarding
Memory allocation strategies
Custom allocators
Memory pools

Performance

Zero-cost abstractions
Inline optimization
Template metaprogramming
Compile-time computation (constexpr)
Cache-friendly data structures
SIMD operations

STL Containers

Sequential Containers

#include <vector>
#include <deque>
#include <list>
#include <array>

// vector - dynamic array
std::vector<int> vec = {1, 2, 3, 4, 5};
vec.push_back(6);
vec.emplace_back(7); // Construct in-place
vec.reserve(100); // Pre-allocate capacity
