Okay, in our programming we also have these what we call this, this will be one of the data structuring our programming. So for vector we stall I see a few elements or a few values of the same data type. These we can install a few elements or a few values of different data types. So we can create a police using something IDs, these, okay, so one, two, AB, a and then B. Okay, I want to print these lists I can do something like this. Okay, one two A B.

So if I want to go into the cross and type off this I can do something like this. And then a type or less favorable one. Okay Ctrl A and then I run. Okay, so I get the lease the lease. Let's say I want to go into, let's say, I want to select a second thought and fourth element. I can do something like this terrible one, let's say minus one.

Okay, I pre run. I get a second time for payment. If I want to select let's say the first and fourth element. I can do something IDs. See one, four. Okay.

Control eight and not run. okay to be available One okay so Ctrl eight and I run so, I get a first and Bob element. So, if I say I want to get something if I want to get the values, so, I will see all these are the Sundays if I only want to get that news I have put to something that is variable one two square i can i say ah say the first element. So, now I will get the first values okay. So, I will know if I see I want to get the ah if I say I want to modify one of the elements, I can do something IDs Okay. Let me see it Maybe one less.

So I modify these to the C and E number nine. I think we'll have error. Okay, let me see the old one. Okay, so I got the Modify the first element tonight. Okay, first element tonight. Okay, so this is roughly how we added a lease, create a lease and then a modified lease.
