However, it turns out that in the case of conscious usage of selected language features it can be relatively easy to produce high-quality software with great performance and resistance to programming errors. Such a coding style is called 

The training targets the developers who already have professional experience with C++ programming language and who know the problems caused by the careless way of coding in this language. The workshop aims to strengthen the knowledge about the C++ language and show how to avoid many of the problems that often appear in the production code.

This training should be considered a mandatory training for all C++ developers and code architects. It is a foundation for all other C++ trainings offered by Train IT.

Emphasis on understanding the philosophy and mechanisms of C++ programming language and learning how to reuse this knowledge in own code

Particular focus on the usage of C++ templates in practical tasks

Selection of useful patterns and techniques that prove in a demanding production code

The following plan is an initial proposal for the training material. The final agenda is always created based on the individual pre-training analysis of the client's requirements and constraints.

Utilities that every C++ developer should know and use

2 Days

Advanced Modern C++

C++/Embedded

In this two-day workshop, you will learn about good unit tests (GUTs) and test-driven development (TDD) by seeing what it takes, putting them into practice, and reviewing what you've learned. What practices support readable and maintainable tests? What test pitfalls hold developers and products back? How do you make testing fun and not a chore? Come along to answer these questions and more.


The workshop includes lecture, hands-on coding exercises, and Q&A. The examples and hands-on exercises will use C++, but you don't need to be a C++ guru to take part. We can also discuss similarities, differences, and challenges of unit testing across different codebases, with different frameworks, and in other languages.

Driving Your C++ Code with Tests

Testing

 is a two day training course. It is ideal for new hires that have little to no experience in C++, but are proficient in an Object Oriented Programming language, like Java or C#.

 should ideally be taken before Mod(C++) Intermediate, another two day course which expands on the topics in Mod(C++) Fundamentals. Taken together these two courses will give a good foundation for a modern C++ programmer.


The Fundamentals course gives the students an understanding of how one should think and program in “Modern C++” (C++11/14/17/20). The exercises will all be based around a 2D graphics game inspired by PacMan. Topics covered in the course include:

Variable and function use, including auto, const, overloading and function templates

Namespaces, classes and structs, when and how to use them

Standard library containers and algorithms usage

How to efficiently use values and references

Memory theory, including understanding allocation on the heap and stack

RAII and lifetime management, including Rule of Zero

Lambda functions and using them with standard algorithms

An introduction to the C++ compilation model and advice to make the best use of compilers and build systems

Students are assumed to be proficient in anObject Oriented Programming language like Java or C#. They should be working in (or looking to work in) a C++ project.

The exercises will be done in a CMake based project. The students will need a development environment, a rich IDE is recommended, for example Jetbrains CLion, QtCreator or Visual Studio. A GitHub account will be useful.

10. Privileged programs (+)
* Set-user-ID and set-group-ID programs

The following people are likely to find the workshop of particular benefit:
* Programmers developing system-level applications for Linux systems, or programmers porting such applications from other operating systems (e.g., Windows) to Linux.
* Embedded programmers developing applications for Linux, or porting embedded applications from systems such as VxWorks or QNX to Linux.
* DevOps engineers and sytem administrators who want to gain a greater insight into the oepration of Linux applications.




The workshop consists of a mixture of detailed presentations coupled with many coding exercises that allow participants to apply the knowledge learned in the presentations.




* You should have a good reading knowledge of C or C++. For the practical sessions, templates will be provided to relieve you of the need to type in tedious boilerplate code. The templates are in C, but if you wish, it is also possible to complete the exercises in another suitable language such as D, Rust, or of course C++.
* You should have a basic familiarity with the Linux/UNIX command line to do tasks such as listing directories, editing files, and compiling programs.
* No previous system programming experience is assumed.




You'll need a laptop with Linux installed--either as a native install or inside a virtual machine (VM). In the latter case, you should ensure that the VM has working Internet access. The system should have a C compiler (e.g., gcc) and "make" installed. (It's likely that both of these are provided as part of the default install, if you are setting up a new system.)
