1. Modern C++ in practice

2. Goals Practical experience of C++ best practices, idioms and details
Design patterns in C++
Generic, functional and template programming
Using boost and STL
Utilize APIs, books and mailing lists
Coherent coding style and get to know each other

3. Why bother with details?
Cons
More than 20 years old
Backwards compatible with C
Lots of mistakes in both language and library
Very complex
Pros
Powerful features
Well spread
Vivid community
Rapidly developing

4. Polymorphism in C++ Virtual keyword Function pointers
Function overloading
Implicit type conversion
Concepts
Policy classes
Argument dependent lookup (ADL)
Partial template specialization

5. C++ programming Object oriented programming Generic programming
Functional programming
Template metaprogramming
Blend these paradigms to acheive code that is
Simple and easily read
Decoupled and testable
Robust to change
Reusable

6. Roadmap Very unclear Start today and see how it evolves Think about:
What you want to learn?
Should we add or remove goals?

7. Today boost::variant boost::signals
Discuss slots n’ signals relation to bind and function
My observable class
Pair-wise design of a toy problem
Discuss design differences

8. Toy problem: Cat n’ Rat
Design logical interfaces and concepts for a simple game 2D discrete coordinate world Contains cats, rats, cheese and obstacles Move events appear for cats and rats Collision detection, not handling

9. Toy problem: Focus Focus the design on When working try to
Low coupling, high cohesion
Robustness to future changes
Event driven information flow
When working try to
Use boost and STL
Push error checking towards compile and link time
Write generic code when it doesn’t complicate design

10. Future suggestions Implement logical model Design and maybe implement:
Text view
Collision handling
Serialization
Simple client/server
Extend game functionality
Implement message distributor
