 So the question is, where is it going to compile? So notice that there is a link here, it's not aware. Will this line compile? Raise your hands. I'm not going to ask you, you know. Yes, it does compile. Why? I'm sorry that I didn't see this part, sir. Alright, there's more. You do it like you do not? Oh yeah, so I asked you the wrong answer. You do it like you do not? The reason is, you are basically accessing the property of the classy. But what about this? Let's say, will this compile? Level 2? No, no. That is correct. Okay, moving on. What do you without of this? Well, basically you have a fault through here. Will it come out of the switch or will it replace or will it replace? Yes? What do you mean? What do you mean? That is wrong. Basically the fault through comes to the next case. So if you don't have the second one, then you can print this one. Okay? What will be the result of this? Raise your hands. Who said press? That is correct. It is going to press. Because you are returning two items and the index is zero and one. If you put zero, basically it is going to print the first thing. If you put one, then it is going to... So on the similar line, basically it is returning a tuple, right? Those of you who are familiar with tuples basically it is returning a tuple range. Do you know if there is a maximum limit to tuple? How many values can be written in tuple? How many? No. Six tuples are more than you can written in tuple. Anybody knows? I don't think so. No? I think the rate is close to two thousand. But then you would be crazy if you are returning two thousand values in a tuple. Having said that John, you... Sorry, Paul. You... You get a... You have to take your... You have to try it because it is common in this system. But in the last one, now if you have been focusing on agent stuff, you should be able to accept this. Is there any difference between these two? Anybody wants to give a try? Option one is a... Option one of the string type. String optimum. Is there any difference between these two? The first one specifies that there isn't a value. The second one says that it has a value which is none. There is no difference between these two. The second one, which is basically optional. None is enum. It's literally milk. It's basically syntactic sugar. If you basically do a write a if statement and compare these two, it's going to actually bring trouble. So having said that, those of you who attempted... Okay, so I'm going to give you a quick announcement about the IOS con. Some of you have bought the tickets already. The website is IOScon.org. We just announced the complete list of speakers for this year. This is a great list, according to me, because I have been changing some of them for close to a year. I spoke to Nathasaya last December last year to get her to concentrate this year. We just sold the super early board tickets. And the early bird price is 280. However, if you put IOS Dev Scott, it is not a lot from super early bird, but you need to purchase before 15th of September if you want this 20% discount. And I think we will update the agenda of the talks in a week or so until finalizing some of the speakers. That's it from my side. But tonight, thanks to Stephen and Hyde for sponsoring the gifts and food. This is the end of the meeting, but anyone has any announcement to make? Anyone looking for a job?
