C++ For Programmers (Udacity)

CS: Programming

Learn features and constructs for C++. C++ for Programmers is designed for students who are familiar with a programming language and wish to learn C++. This course focuses on 'how' as opposed to 'what'. For example, in the lesson on functions, we do not teach what a function is, but rather how to create a function in C++. The lessons are taught by several different instructors who have used C++ in their professional careers, so students get to experience different perspectives.

Organizing Code in a Disorganized World. This course covers methods for organizing your code, both conceptually and literally. You’ll learn the importance of separating concerns when writing JavaScript, gaining hands-on experience along the way. Separating concerns can be done with or without an organizational library or framework. We’ll learn how to separate concerns without one, and then we’ll explore an organizational library together. You’ll also learn strategies for exploring other libraries and frameworks on your own.
