Summary

This was only the first chapter of the book, but it contained quite a lot of information that will be useful while reading the remaining ones. At the beginning, you saw that using proper data structures and algorithms is not an easy task, but could have a significant impact on the performance of the developed solution. Then, the C# programming language was briefly presented with a focus on showing various data types, both value and reference ones. Classes, interfaces, and delegates were also described.

In the following part of the chapter, the process of installation and configuration of the IDE was presented. Then, you learned how to create a new project, and its structure has been described in details. Next, you saw how to read data from the standard input stream, as well as how to write data to the standard output stream. The read- and write-related operations were also mixed into one example.

At the end of the chapter, you saw how to run the example program, as well as how to debug it using breakpoints and step-by-step debugging to find the source of the problem. What's more, you learned the possibilities of the Immediate Window feature.

After this introduction, you should be ready to proceed to the next chapter and see how to use arrays and lists, as well as accompanying algorithms. Let's go!
