Content:

1. Syllabus
   Describes topics to be covered, reading material for you to digest before coming to class, and due dates for the assigned projects.

2. MTMU Help Sessions:

   • Friday, 4/28 at 10:30am in CST 4-201 (Project #4 help from 9:00am to 10:30am)
   • Friday, 5/5 at 9:00am in CST 4-201
     
     Note: time and place have changed to 5/5 at 1:00pm, 369 Link Hall

3. Projects:

   Project #4, Project4HelpS17
   Remote Code Publisher

   Project4HelpS17
   C++\CLI WPF client that sends and gets messages using native C++ mock channel.
   C# WPF client with C++\CLI shim that sends and gets messages using native C++ mock channel.
   Also included are several diagrams that illustrate design ideas for Project #4 and some sample Socket code.

   Communication Channel, vsdx
   Diagrams for Peer-To-Peer communication, Client and Server communication processing, and Message structure

   Mock Channel Demo, vsdx
   Diagram illustrating native C++ to C++\CLI interoperation for the Project #4 GUI via a mock demo.

   Note:

   Project #4 is due Tuesday, May 02. We will charge 1 point per day for Wednesday and Thursday. After Thursday midnight the late fee increases to 5 points per day. Also, after midnight Thursday, we will not count bonus points. This is necessary since we have a very short time to complete grading projects and submit course grades.
4. Unit Test Framework

5. Preliminaries:

   Program Scope and global data
   Scope inclusion rules

   Programming Languages, vsdx
   History of imperative, functional, and scripting langugages.

6. Template Metaprogramming

   Template Techniques

   Template Metaprogramming

   Binary Conversion at compile time
   compile time functions
   compile time loops
   compile time selection
   compile time switch case
   compile time type lists
   compile time lists improved
   

7. The D Programming Language:

   • D Programming Lanaguage
     
   • D's templates
   • Three unexpectedly successful features of D
   • Andrei Alexandrescu's Home Page

8. Open Source Libraries:

   • Boost Library
   • Loki Library

9. C++11 - new features

   Herb Sutter's excellent and brief overview from his Blog

   C++11 concurrency
   Threads, locks, condition variables, async, futures, promises, packaged_tasks, and atomics

   C++11 BlockingQueue
   Uses condition variable and mutex to build a queue that blocks deQers when empty.

   Str strings
   Demonstrates move constructor and move assignment.

   Component Reference Counting
   Demonstrates variadic templates and functions.

   Symbol Table
   Illustrates how using aliases are a great design tool. Also demonstrates range-based for loops.

   Chrono Timer
   Uses Chrono library to build a high resolution timer precise to about 100 nanoseconds.

   Callable Objects
   Demonstrates lambdas and compares them to function pointers and functors.

   Singleton
   Uses atomic.

   Uniform Initialization
   Illustrates use of uniform initialization for user defined types and STL containers.

10. C++11 - The new standard:

    C++ Reference - includes C++11

    What is C++11?
    A guide to Lambdas
    Local, anonymous function definition
    Move semantics and rvalue references
    Pass by value and return by value doesn't need to make copies
    make_shared
    Don't need delete if you use make_shared smart pointer.
    Type Inference
    Type declaration using auto that adopts the type of an expression result.
    Range-based for loops
    C++11 Thread support
    std::Thread documentation.
    C++ 11 std::async
    Clean semantics for calling a function asynchronously.
