+Welcome to the **exercises**. Now we are going to write a couple of console applications, by which we are going to make a few more steps into programming. After that we will show how we can program something more complex – programs with graphical user interface.
 
 ## What We Learned in This Chapter?
 
-First we have learned **what is programming** - **giving commands, written in a computer language**, which the machine understands and is able to execute. We understood what is **a computer program** - it represents a **sequence of commands**, arranged one after another. We got familiar with **the language for programming C\#** on a base level and how **to create simple console applications** with Visual Studio. We followed **the structure of the programming code in the C\# language**, as for example, the fact that commands are mainly given in the section `static void Main(string[] args)` between **the opening and closing curly parentheses**. We saw how to print with `Console.WriteLine(…)` and how to start our program with \[**Ctrl + F5**\]. We learned how to test our code in **SoftUni Judge**.

 Some programming languages do not use a compiler and are being **interpreted directly** by a specialized software called an "interpreter". **The interpreter** is "**a program for executing programs**", written in some programming language. It executes the commands in the program one after another, as it understands not only a single command and sequences of commands, but also other language constructions \(evaluations, iterations, functions, etc.\). Languages like PHP, Python and JavaScript work with an interpreter and are being executed without being compiled. Due to the absence of previous compilation, in interpreted languages **the errors are being found during runtime**, after the program starts running, not previously.

 **Environments for development** are convenient, because they integrate everything necessary for the development of the program, without the need to exit the environment. If we don't use an environment for development, we will have to write the code in a text editor, to compile it with a command in the console, to run it with another command in the console and to write more additional commands when needed, which is very time consuming. That is why most of the programmers use an IDE in their everyday work.
