Course Overview

C++ started in 1979 as an experiment, before being officially launched in 1983. In 1998, its first ISO standard was released. What started as an experimental language has quickly turned into a platform for solving complex problems that drive many industries: gaming, finance, data centres, vehicles, and even software for space missions, among many others. The latest release, C++17, builds upon the functionality of previous versions by further diversifying the power of C++ and increasing the language's readab...Show More
