‫Welcome back.
‫In this chapter, you are going to learn a bunch of different topics which aren't really connected to
‫each other, but they are still important parts of programming.
‫So you're going to see what structs are enemies, access modifiers, the math class, random class,
‫state class, how to use regular expressions, which is very important.
‫You're going to see what numbers are.
‫They are a concept that is called differently in different programming languages.
‫So it really depends on which programming language you use.
‫And they have a similar meaning, but still they are slightly different.
‫Then we're going to look into the garbage collector.
‫We're going to see how abstract works and a lot more.
‫So I'd say let's dive right into it and enjoy this chapter.
