Design Patterns

What are Design Patterns (later DPs)? DPs are typical solutions to problems that occur often when developing software, more specifically in the design phase. They describe a recurring problem and the way to solve it as well as the consequences of applying it.

Types of Design Patterns

There exist three types of DPs:

• Creational: they describe the way objects are instantiated;
• Structural: they are concerned with the way objects are composed;
• Behavioural: they define the way objects behave and interact between themselves.

Structure of the Repo

Every folder of this repo represents a DP and includes:

• a theoretical explanation of the problem it solves and how;
• a UML representation of the pattern. Use PlantText to copy-paste the PlantUML code of each DP;
• a description of the elements of the pattern;
• a code example in C++. You will need g++ (sudo apt install g++) to be able to compile the code examples (instructions to compile and run the code are provided).
