One of its central features is object-oriented programming (OOP) as well as generic programming, which allows programmers to create efficient, easy-to-maintain and reusable code. C++ is widely used by programmers to develop application software with a personal computer. C++ has been the language of choice for many CPU libraries over the years. C++ CPU libraries are a staple for anyone working in artificial intelligence or machine learning. The availability of libraries in C++ has drastically reduced the time required to develop complex programs and applications. A few of the most popular C++ CPU open source libraries for developers are: thunder svm - Thunder SVM: A Fast SVM Library on GPUs and CPUs; mshadow - Matrix Shadow: Light weight CPU/GPU Matrix and Tensor Template Library in C/CUDA for Machine Learning; ToyPathTracer - Toy path tracer for my own learning purposes.
