What's going on guys? This is Bucky. Welcome to your sixth c plus plus tutorial.
0:04
And in this tutorial, I wanna go over some concepts with variables that are
0:08
definitely going to help you later on.
0:09
So, the first thing I wanna go over is this. You remember last
0:13
tutorial,  I told you guys at they're basically two different ways to create
0:17
variables?
0:17
The first way is to create a variable called "tuna" or something
0:20
and set it equal to the value like 43 all on one line.
0:24
Simple enough, easy to understand. Well, what I also told you guys you can do is
0:29
you can declare aka "create it" on one line
0:32
and set it to a value on other line such as that.
0:36
They're both perfectly acceptable ways to do things.
0:39
The one thing I want to  stress is that whenever you do it this way,
0:44
declare on one line and set equal to the value on another line,
0:47
you don't need to write what type variable it is, again.
0:51
Once you give c plus plus the information up what type of data you're
0:55
working with
0:56
you don't need to list it every time you're working with variable. C Plus Plus will
1:00
remember that information.
1:01
Aand
1:02
You know, it will keep it. So, whenever you're working with "tuna" later on
1:06
you don't need to explicitly write "int", and actually you can't, or else it will give you an error message.
1:11
So, just make sure that now just remember that don't write "int" twice
1:15
on the same variable. So, aside from that, let me show you guys this.
1:20
int tuna equals 99. So, later on
1:24
and I didn't tell you guys this, but what you can do
1:27
is if you set tuna to something else like
1:30
76, whenever your computer creates a variable
1:35
it sets aside a piece a memory to store that value. In this case 99.
1:39
Well whenever you create, or excuse me,  whenever you use that variable. 
1:44
again and set it equal to a new value what your computer is going to do is it is gonna
1:48
wipe out the old value,
1:49
in order to make a room for the new value. So now you said alright,
1:53
we have a variable called "tuna" and that's equal to 99.
1:57
well now, we have a variable called tuna
2:00
and we want that set the sick with 76. Well alright.
2:04
So, we're going to try to print out tuna in our computers gonna say alright.
2:08
Should I print out 99 or 76? Well, since we created one originally
2:13
that was 99 and then we overrode it to make it
2:17
76 is gonna print out 76. So, let's go ahead and build and run this.
2:21
And see what you get? 76! So, basically
2:25
whenever you have a value it's placed in a memory
2:28
location and then whenever you get that variable
2:31
a new value its gonna overwrite the old value
2:34
and put it in the same location. So, I just want tell you guys that
2:38
this is how you can overwrite variables, so if you're expecting 99 and you got 76,
2:44
this is why. So, that's actually all I have for you guys as for this tutorial.
2:47
Again, the two things I wanna stress is, whenever you're creating a variable
2:52
you only write the type once!
2:55
You don't need to write it every single time. And then whenever you need to reassign
2:59
value
3:00
just go ahead right variable name and not the type again. And also
3:04
whenever you're over writing a variable, you use the variable and its can be equal to
3:09
the latest
3:10
value. So, whenever you, you know, set this equal to 76
3:14
is going to wipe out the 99 and use the 76.
3:17
I just want to stress those, a couple memory concepts.  Then
3:21
whenever building programs later on you might have a better understanding of 
3:24
how it works.
3:25
So, for now that's all I have for you guys and the next tutorial.
3:29
You know how I said that we're going to be going over arithmetic, like,
3:32
how to add two numbers together well there's actually a bunch of different
3:36
arithmetic operators that we need to learn and that's we're going to be covering in
3:40
the next tutorial.
