Okay in our programming we have this function. So for function we can use it to reuse, reuse our code in Alessia ah different parts of these, our programming code. So let's say I create a function cream Hello okay to question okay. I can write something up a Hello okay. I can call this function in hello world. I can call you a few times in hello world then a Hello World okay then I can say so that all Ctrl A and then run the code Okay so I print three times all over.

So, for calling this our nation we must always have expansion here first then we call this function after these are after expansion integral here he cannot police a print aloha apologies machine you know called is a function above here will give us an error okay. So in this function we know so I have some of the parameters and some some of the parameters and then some return values okay so let's say I want to create a mean function I can do something like this. e eight as last and the Then I will return I read the lower one. So a less than b i will return a okay I say put a bracket here then else else I can do something like these three be okay then I can call this function mean I see some number and then some number and then Ctrl A and run so, I get 1221 which is the minimum between these two number okay what is function means C is 1221 is a pasta these are parameters here and then this value is This parameter here is a i want to i if this value 1221 is less than b 123123 then return a 1221 as we return these are 123123.

So, this is a way to write this function. Previously we write the print HelloWorld function, we do not put an essay on any of these parameters or return any values. When we write this minimum function we put in some parameters and return some values. So, in our programming, when we write function, whether we put in these parameters our return values is up to
