Open-source course "High-Quality Programming Code". Contains lectures and other teaching materials.

The „High-quality programming code” course objective is to introduce the students to the principles of high-quality programming code construction during the software development process. The quality of the code is discussed in its most important characteristics – correctness, readability and maintainability. The principles of construction of high-quality class hierarchies, classes and methods are explained. Two fundamental concepts – “loose coupling” and “strong cohesion” are defined and their effect on the construction of classes and subroutines is discussed. Some advices for correctly dealing with the variables and data are given, as well as directions for correct naming of the variables and the rest elements of the program. Best practices for organization of the logical programming constructs are explained. Some methodologies for testing, debugging and code optimization are introduced. Attention is given also to the “refactoring” as a technique for improving the quality of the existing code. The principles of good formatting of the code are defined and explained. The concept of “self-documenting code” as a programming style is introduced. The techniques and practices for constructing high-quality programming code discussed in the course are independent of the programming languages.
