Many aspects of the C++ language are covered from introductory to more advanced. This material includes: language basics (objects, types, values, operators, expressions, control-flow constructs, functions, and namespaces), classes, templates (function, class, alias, and variable templates; template specialization; and variadic templates), lambda expressions, inheritance and run-time polymorphism, exceptions (exception safety, RAII, and smart pointers), rvalue references (move semantics and perfect forwarding), concurrency (sequential consistency, atomic memory operations, data races; threads, mutexes, condition variables, promises and futures, atomics, and fences; happens-before and synchronizes-with relationships; and sequentially-consistent and other memory models). A number of best practices, tips, and idioms regarding the use of the language are also presented. Some aspects of the C++ standard library are covered, including: containers, iterators, and algorithms; the std::vector and std::basic_string classes; I/O streams; time measurement; and smart pointers. Various general programming-related topics are also presented, such as material on: good programming practices, finite-precision arithmetic, software documentation, software build tools (such as CMake and Make), and version control systems (such as Git).
