With 10% discount you can bundle you know you can purchase bundle books or video tutorials and all those things. With the free ones you can purchase a single PDF book related to the sweep learning sweep or watch kit or code data whatever you like and inside is not opening. Yeah if you go to store say you have all these kind of things that you can purchase. The sweep books are really good. The game programming books are really good. I used to write for rey earlier. I stopped because I couldn't spend much time on it but I have personally read a lot of these books and learned a lot from these books. Okay so let's start with the quiz. The way it's going to work is you raise your hand don't yell the answers. These are very basic sweep questions and very basic like probably if you've learned sweep these are the things that you've learned on day one or first hour or something but it will go interesting you know we'll ask more advanced or intermediate questions as and when we progress to the next meetups and all but let's start. Raise your hands and I'm going to randomly ask you if you give the right answer you take it with a free video boop on other way you take the 10% discount that's for participating. Okay raise your hand. Okay who wants to go voluntarily answer you damn it. Strange. A lot of people you haven't probably started with sweep the way sweep function or method works you can pass arguments here any number of arguments you pass the parameter name they say I pass argument one and followed by colony pass the type of that argument it can be string or integer whatever and you can pass any number of arguments there similarly anything that is after this arrow that is the written type basically you can written multiple parameters in your written type that you call as a tuple so you can let's say your function or the method is going to return multiple elements then you can have something like then you can return more than one values from this function okay that was easy right so instead of this thing for type values which is which we didn't have actually I think in Objective-C now how do you read at the second line okay okay that's the right answer and the remaining ones I'm not going to take home and you can just grab either on call with 10% discount and if you are planning to purchase a book any of these books you can take from me again the same thing is let's say you have a parameter sorry variable whatever that you want to declare the certain type you can type alias your type to something else that you want that makes sense with your logic so here I type alias zombie as zombie int and I can just modify the second line and zombie int which is basically a type alias of zombie int and the bar stands for is a variable if you have something that is not a variable you just use let which is basically a constant so that's it for the quiz tonight the four is finished but if you want to hang around for a while and talk to other developers feel free to do so there are drinks outside you just press something on the vending machine whatever thing you want feel free to talk to each other and you know make new friends thank you
