2 ..to the Berlin BAU Software Lab! Let's have two interesting weeks together! (c)schmiedecke C# and.net 2

3 Ilse Schmiedecke studied Computer Science in (West-)Berlin in the 70-ies married for more than 30 years, adult children teaching software engineering and programming at the "Beuth Hochschule" in Berlin and love it (c)schmiedecke C# and.net 3

4 first week 50% lecture, 5o% exercise second week small project, additional lectures breaks as you need them tell me work in pairs assignments: follow-up on exercises small reviews every morning -- for self-assessment review-exam next Monday final exam after the course grading: 49% practical work, 51% written exams (20+31) attendance and lists.

5 Use what you have learned C# is much like Java but we will discuss language matters on a more professional level Enjoy using cool tools and libraries << a fool with a cool tool is still a fool but cool>> Learn to find out I will not give you all the details but I willl help you if you get stuck. (c)schmiedecke C# and.net 5

6 Form pairs Look at the code handout and try to understand what happens language problems? -- ask me syntax or semantics problems? -- guess! afterwards: Run the secret.exe file. (c)schmiedecke C# and.net 6

7 C# is an object oriented language very much like Java a little more modern (int is an object) much more features and add-ons (to keep experienced programmers happy) classes, inheritance, interfaces, polymorphism simple and structured types, generics type safeness beautiful GUIs phantastic ready-made data types great libraries easy networking and webworking (efficient graphics processing) (c)schmiedecke C# and.net 7

8 value objects reference parameters block matrices unified type system properties indexer iterators delegates lambda expressions data queries don't worry, be happy! (c)schmiedecke C# and.net 8
