C++

What you'll learn

• Compile and structure C++ programs with headers, source files, namespaces and warnings.
• Use types, functions, references and parameter passing correctly in modern C++.
• Manage memory and resources safely with RAII, containers and smart pointers.
• Design classes with constructors, copy and move semantics, inheritance and virtual functions.
• Use the standard library: containers, algorithms, lambdas, ranges and vocabulary types.
• Write generic and robust code with templates, concepts, exceptions, threads and sanitizers.
