What is going on, guys?

And in this section, we are talking about loops.

So loops, loops is considered to be a very powerful tool that we will use a lot in these Kooris and

in some of our future courses.

And basically only is simply allowing us to loop or to run over and over again some piece of code to

repeat some block of commands multiple times.

And that's not exactly what we've used so far.

Right.

That's not something that we've used in the previous videos or in the previous sections.

So we can say that up to this section, if we had some written commands, whether they were input output,

math operations or whatsoever, we knew that these commands will be executed just once.

They will simply be executed one after the other.

And once you're getting done with them, once you're done with them, you will move on to the next commands.

So you run some commands.

You're finished.

You're moving onto the next commands.

But there will be times when you would like to take some commands and repeat them, repeat some block

of code, not just running at once.

And one way to do so is by using a copy and paste technique and well, simply to copy some commands

and then beat them in your code as many times as you would like.

So that would be option number one.

And although this messy approach may work for some tasks, there are other challenges that this approach

will not even be capable of solving.

And luckily for us, as the future awesome programmers who know all the programming concepts right,

once we started loops, we'll be able to write such cool programs that we'll be capable of repeating

the same task, the same code over and over again until we tell it to stop.

And this will be done by using these awesome loops, statements instead of these messy copy and paste

approach.

So in this section, we are going to talk about loops and explaining details, what is a loop concept

and take a look into a couple of different types of loops, including while loops and for loops.

And we will learn how they can be used.

What are the differences between each of them?

What are the similarities and when you should prefer using one over the other?

We will also talk about what is an iteration and what it has to do with loops.

We will see how we can get out of loops.

What are the commands to do so?

And what loops have to do with the control, flow and conditions that we've learned in the previous

sections.

Also, if we will have time, we are going to take a look at a couple of examples and the concept of

using nested loops, which is similar to nested conditions just with loops.

It simply loops inside loops.

So basically is going to be fun and we will just enjoy this lesson a lot.

So in addition to all the interesting concepts that we are going to learn in this section, you are

also going to develop a really cool program that is going to answer the ten cents versus million dollar

question, which basically stands for if you would rather have one million dollars right now or you

would rather have one cent knowing that it will be doubled every day for the next 30 days.

And what you are going to do is you're going to develop a program that will be able to calculate and

answer this very interesting question.

So later on, you may either a share the school question as well as these program with your friends

and colleagues to see what they think of it.

And to let them choose what they think they would take and probably to prove them wrong.

So I hope you're ready for this section.

And let's get started.
