Design Patterns in C++

Course objectives

After completing this course you will be able to:

• improve the design of your object-oriented code
• apply the principles of Clean Code and SOLID OOP to your project
• recognize the context in which the appropriate design pattern can be implemented
• implement the appropriate pattern
• refactor the legacy code to patterns (Refactoring to Patterns)
