In the week from 16.09 – 20.09 we started the introduction in C# with Christian Becker in a large group. The first topics were Sourcetree, Git and Azure DevOps to get familiar with version control. The first step was to create your own repository to manage your projects. Then we got an introduction to C#. It started with the basics of the programming language itself, variables and the console were the first topics to be covered. After 1–2 days we started with lists and arrays, all topics were tested with small programming tasks. These were also always discussed afterwards with Christian, so that everyone who still had open questions could ask them. At the end of the week there were 2 briefings on certain topics, on the one hand the topics travel expenses and health and safety instruction. The briefing in the travel expense accounting was accomplished by our Financial Accountat, thereby we, the apprentices/students, were allowed to type in an example journey in Concur, in order to illustrate this visually and in order to become acquainted with the most necessary if one has times a business trip before itself. The next day we had the second and last lecture for the week, which was about health and safety instruction.
