Quick Reference

Topic	File
RAII, smart pointers, new/delete	`memory.md`
Raw pointers, references, nullptr	`pointers.md`
Rule of 3/5/0, inheritance, virtual	`classes.md`
Containers, iterators, algorithms	`stl.md`
Templates, SFINAE, concepts	`templates.md`
Threads, mutex, atomics	`concurrency.md`
C++11/14/17/20, move semantics	`modern.md`
Undefined behavior traps	`ub.md`

Raw new without delete leaks — use std::unique_ptr or std::make_unique
Returning reference to local — undefined behavior, object destroyed on return
== for C-strings compares pointers — use std::string or strcmp()
Signed integer overflow is UB — not wrap-around like unsigned
Virtual destructor required in base class — otherwise derived destructor skipped
std::move doesn't move — it casts to rvalue, enabling move semantics
Moved-from object valid but unspecified — don't use without reassigning
Data race on non-atomic is UB — use std::mutex or std::atomic
vector<bool> is not a real container — returns proxy, use deque<bool>
map[key] inserts default if missing — use find() or contains() to check
Braced init {} prevents narrowing — int x{3.5} errors, int x(3.5) truncates
Iterator invalidation on push_back — vector may relocate, invalidating iterators
string_view doesn't own data — underlying string must outlive the view
