C++ Design and Best Practices

C++ is an exquisitely rich language, packed with fascinating language features and extensive library capabilities. Learning the syntax and STL nuances is a task in itself. This course goes beyond the syntax and library to focus on C++ design principles and best practices. The course describes how to design C++ systems so that they are modular, maintainable, extensible, and pluggable. We take a detailed look at the SOLID principles and see how to apply them using modern C++ techniques. We also lift the lid on many design patterns, implementation patterns and C++ idioms and see how they remain relevant in C++ today.
