TDDD38 Advanced Programming in C++

seminars

Seminar 1 is given as a quick introduction to basic C++, actually prerequisites. If already familiar with C++11, you may consider to skip seminar 1, but have a look at the material.

All the old lecture slides are available as pdfs for each seminar. There is also a rendering in HTML available with links to the topics covered here

Full size seminar slides are linked from each topic heading. [2x2] shows miniatures, 4 slides per page. Also the two larger, complete code examples used for seminar 4—5 (String) and seminar 6—7 (P-E-M-C) are linked below.

Extra material will be added here during the course and on the course GitLab group.

Using templates and pointers to members to create a comparator for structs
Doing folds with help of variadic templates
A solution to get folds working without the tools available in C++17 fold expressions

Cpp Core Guidelines
" The aim is to help people to use modern C++ effectively. By "modern C++" we mean C++11 and C++14 (and soon C++17). In other words, what would you like your code to look like in 5 years' time, given that you can start now? In 10 years' time?"
