Our training focuses on the approaches and methods for improving source code readability in C++. During it you will have the chance to practice refactoring small programs, focusing on various aspects of improving the existing code.

To be determined
Is your source code difficult to read? Do you spend a lot of time trying to understand what the developer wanted to do with a particular code fragment?
If you find yourself in these types of situations, this training will be useful for you. You’ll learn about code smells, why and where they appear, and what techniques are used to remove them. We will start from simple problems in a single function and end with problems of communication between classes. We will also discuss what should and what should not be done to make your code easy to read.
