Modern C++ Software Design (Advanced)


Oct 21, 2021: Update of information concerning lunch and breaks.

This advanced C++ training is a course on software design with the C++ programming language. The focus of the training are the essential C++ software development principles, concepts, idioms, and best practices, which enable programmers to create professional, high-quality code. Additionally, the course gives insight into kernel development with C++. The course provides insight into different design strategies (object-oriented programming, functional programming, generic programming) and the philosophy of “Modern C++” and teaches guidelines to develop mature, robust, maintainable, and efficient C++ code.

Please note that this course is not a tutorial on any specific C++ library or tool (as for instance OpenFoam or CUDA), but teaches good, mature software design with the C++ itself.

Since 2020 we provide two types of C++ courses, each offered two times per year:

  • intermediate: Mar. 2-5, 2021, and July 6-9, 2021
  • advanced: May 4-7, 2021, and Nov. 23-26, 2021 (this course)

with two different levels of prerequisites.

On-site / COVID
On-site course & COVID rules

Although this event is a training course, another important aspect is the scientific exchange between participants, which did not work as well as we hoped in our online courses.

The concept to enable this communication among our participants consists of

  • common coffee and lunch breaks, and
  • if you want and permitted by COVID-19 rules in November, working together in groups of two during the exercises.

For your security, we allow only completely vaccinated, or fully recovered, or participants tested negatively on COVID-19 on all days. In the course room and when not eating/drinking, FFP2 masks are required. See here for details. Of course, these rules also apply to the instructors.


Prerequisites Advanced C++ (this course):

At least two to three years of experience with the language is needed. This includes a solid knowledge of the syntax of C++, experience with the standard library (std::vector, std::list, …), hands-on experience with both template-based and inheritance-based designs and some experience with design patterns.

Prerequisites Intermediate C++ (other course type):

At least one year of experience with the language is needed. This includes a good understanding of the basic mechanics (header files, source files, compilation), good knowledge of the syntax of C++ (e.g. pointers and references, loops, conditionals, classes, ...), basic features (constructors, destructors, ...), and some prior experience with templates and inheritance.

Please choose the course that fits best to you!

Gained Skills
Gained Skills

After this course, participants will:

  • have a detailed understanding of the essential OO design principles
  • have gained knowledge about fundamental C++ programming concepts and idioms
  • be able to properly design classes and class interfaces
  • know about the importance of exception safe programming
  • have gained insight into kernel development with C++
  • avoid the usual pitfalls in the context of inheritance
  • comprehend the advantages of value-based design
  • understand the virtue of clean code
Programming Tasks
Programming Tasks

In case of an on-site course, participants will be provided Linux machines. For that reason some familiarity with Linux is expected (login with secure shell, shell commands, simple scripts, editor vi or emacs). Alternatively, participants will be able to use their own machines. Any operating system (Windows, Linux, MacOS, ...), any IDE/editor (MS Visual Studio, CLion, vi, emacs, ...) and any compiler capable of at least C++14 (GCC, Clang, MSVC, ...) can be used. In case of a remote course, participants are expected to use their own machines. The programming tasks, including both Makefiles and CMake files, will be distributed before the course.

If you want a similar course in English, then please look at the 3- or 4-day advanced C++ courses at LRZ , the 4 day course at VSC in Vienna or directly on Klaus Iglberger's course page.

Extended Deadline with late registration

for registration is November 7, 2021 (extended deadline).
Late registrations after the deadline are still possible but maybe with reduced quality of the handouts.

Fee (no coffee)

Students without Diploma/Master: 35 EUR.
Students with Diploma/Master (PhD students) at German universities: 75 EUR.  
Members of German universities and public research institutes: 75 EUR.
Members of universities and public research institutes within EU or PRACE member countries: 150 EUR.   
Members of other universities and public research institutes: 300 EUR.  
Others: 780 EUR.

Our course fee includes soft drinks in breaks (in classroom courses only). See below for details.



There will be several shorter breaks and a lunch break every day. Unfortunately, due to the COVID-19 pandemic, we can only offer water (carbonized and natural) and apple juice in single bottles in breaks but no coffee. If you would like to drink coffee you might bring it in a thermos yourself or you can go to a nearby bakery. All bottles that contain liquids must be safely lockable by a screw cap to protect the laptops and underfloor in the lecture hall.

We recommend that you bring your own lunch. As of today, due to COVID-19 restrictions, there will be no possibility to have lunch at the canteen. We are only aware of the following two publicly accessible nearby places for lunch:
