Introduction into C/C++ Language

For those with a background in a procedural programming language, this course provides a foundation in C++ syntax and usage, as well as object-oriented programming. With this training, you learn how to use C++ functions and variables, leverage advanced features — including constructors, destructors, inheritance, and polymorphism — and gain an understanding of how C++ offers greater ability than C.
