QBASIC Programming Tutorials For Students – 4 – Variables - Duration: 10:24.
What is going on YouTube and welcome to your fourth tutorials on Q Basic now in our last tutorials
We did something like this
Where we declare a variable and assign a value to each now?
I promise you guys that the initiatives are going to be talking about variables
So let's get started now before I start I have written some notes about
Variables which I'm going to show you now
So you can just pause the video and copy it because a lot of time to explain more on them and see what variables are
Meaning of variables types of variables so basically in Cubed z
We have five types of variables now the first one here is what integer variables?
And we all know that integers are whole numbers
whole numbers
Both my - and addition something like this let me show you the example
So you can have something like minus 5 you can also have something like Plus 5
They are always integers integers are just basically whole numbers
so then we have another one called long integer now the difference between this integer and long integer is just
that the long integers
Occupy more integers than this one this one sometimes the coca-cola shot integer
Go solve this please so it occupies a space of - in the CBa - yeah
There's already one ubers is little - okay
Let me just read it out an integer variable sometimes called short integer is a variable that can hold
only integer constants or values in the range of minus
32,768
to R plus
32,000 several resistances
integers integer variables end with a suffix
Percentage sign now if you look at this other one here long integers 100 it occupies a space of this to this now
What you simply study notes is this that this shot integer here occupies a lesser amount of data?
Compared to this long integer here. They also move to the next one which is what single precision?
variable
Single-Precision variables are variables name that n
We dis office call it exclamation mark And I used to hold what?
Single person values that means three numbers and we know what we know
But re numbers are numbers that has what fraction or the hard fraction of points for example
You can have something like three point four. Sorry trip for here closer. Have something like three point four four four four four
They are always fractional
numbers, so that is what real numbers a
Single person values hold the next one is a double position variables they also hold the same thing
But the difference between this one, and this one is that the double position has a larger value compared to what single
variable here this one a hood a
Figure or a significant digits of one to fifteen Amigami from four point a bigger
I want to Delta 15. What is that?
I work a whole significant value or what one two seven as I see in this definition here
So I want you to just pause this video and copy this definition
You have this last variable name here called string
Variables now the string variables used to impute what latest weather which one to type hello world?
Like what we did earlier with a quad hello
What was the value what you need to put it in words in a string variable damages or positive odds?
Double quotation marks like this alright now we've known each of this variable on to tell us how we can declare a variable?
Now to declare a variable is very simple what you need to do is just type in your variable name can be anything
Variable names programmers defined so you can type anything for example? I'm going to type node for numbers then the next thing
I'm going to do is to insert the kind of variable. I want to impute or
Correct you Josey
Then I'm going to put percentage telling the computer that I want to inside words and integer variable called shot integer
So I can just put something like blah like this
But I should not be above this figure here cannot be above this video. This one is - and this one is plus
So you know he was above this figure here
I can just put something like this then I've declared
available then the next thing or going to this other side Daniel declare variable like this see mom - then put a
Exclamation mark which tells the computer that I am declaring a single precision
Variable sorry no C is equals to three point eight four four
Other's blood so we did not the computer knows that this kind of variable with this sign here with this
Exclamation mark you know that these kind of variables are
fractional variables, why did this kind of variables are whole numbers, so
We did explanation. Let's get started with decoding. So what we did here in our last year also declare a string variable
Called hello, then pass in a value
Hello, watsu then pray that it out
So I want to be able to use this example here to show you the different types of variables that we have so I'm going
to we're going to take off this one click of the zone then declare number 11 on one call it a
Kilometer percentage is equals to thirty two thousand seven six seven then the next one there should be 20
known
Sushi be joined together then I'm going to say I'm going to call it ampersand on to a basa
Fine what I'm saying is equals to a whole bunch of integers then the next one thing that you know is going to be
Non 3 we do call it precision sitting ovation is equal to three point it with it and next one is
known for when I know 4 is equals to
Complete a whole bunch of law then as you can see this last one here is a string constant or a string variable
Let's call it variable, so I'm going to leave it like that
Then I'm going to print the whole of will open the whole of this so forth. I'm painting hello
I should be praying rome one dreams no two
prints, no
brains no photo let me start out in July number 78
C90
So I'm going to run this program and see the output all right so as you can see if also on here
Which is hello world this line 50 it printed out. Hello world because the string constant. We look at this place here
We declared hello
I put this dollar sign dollar sign is used to declare a string constant equals was hello then this other place line then here
we declare a number variable and put
percentage sign doesn't this sign is used to declare an integer variable which I call shots variable which ranges from
30
2,750 it's negative sign to
32250 7 positive sign then this other one here
We declare a variable norm Su, and put it ampersand sign. Which is a very long
Integers is up to two million anyways then this the alliant edge that we declared non 3 and put it for our
Exclamation mark Which is a double precision
Variable that means is going to take going to take a fraction of one to seven
significant digits then use other one here known for we declared and
Inserted a hash sign Ashland a is a double position
Variable which is going to take from 1 to
15
Digits then we declare
string constant here and say hello world
So this is the output of the program as you can see there is nothing that is cause off
But if we try to if we try to impute a value here in this num 1 that is above the variable space
You see what will happen like the example
I added 5 5 5 5 5 to this num 1 there on the program once again now you found out that
Even though that it is giving all the difference in entirely out of what we type in here without in three two seven
six blah blah blah
but is giving us 2 1 0 9 1 you know the reason reason is because
This value here is above the memory space that is shot integer can contain so that's the reason why it
Approximated it's 2 this value here understand. I know you understand
then the next thing if we try to in this
Non 3 if we try to put a value that is a both the memory space as we added more
Decimal points there or more decimal numbers they then run the program once again
If another star that it prints out the approximation of this number look at this line test line
33.8
H99 and Anna it
Approximated it to three points. It's nine the reason is because this three point eight
Nine, Anna is above
the memory space that is single precision
Variable can't Contain so what it does to do is to approximate it
So what I need to do is to do what approximate it to the nearest?
significant figure
So with this I know you understand what variables are on how to declare them way to declare a variable?
You just need to do what type the name of the variable?
Followed by the precision or followed by design the type of variable you want to declare?
Which is in this case is percent and possum
exclamation mark
Ash, Mark, and then dollar sign for strings
So if you don't get what I'm saying why I encourage you to do is to go back to our definitions Google
Toa definitions pause the video
And you can read them so you'll be able to get it pause the video here read about read all this
And you'll be able to do what follow along so he talks but for now
I think if you have any question to ask me just drop it on the comments and

MU agree £75million fee for Romelu Lukaku as Mourinho finally looks set to land a new striker - Duration: 7:05.
Manchester United agree £75million fee for Romelu Lukaku as Jose Mourinho finally looks set to land a new striker
MANCHESTER UNITED have agreed a £75million fee for Romelu Lukaku as Jose Mourinho finally looks set to land a top goalscorer. The Belgian looks set to leave Everton with Wayne Rooney heading in the opposite direction.
Romelu Lukaku and Jose Mourinho worked together at Chelsea but the Portuguese sold him to Everton.
Romelu Lukaku finished second on the Premier League goalscoring charts last year with 25 goals.
A deal for Lukaku is not contingent on Rooney heading to Everton, but as SunSport revealed, the former Toffees striker is set to seal a move back to his boyhood club.
According to BBC Sport, the two clubs have agreed a fee in the region of £75m for the striker, with United able to offer the 24-year-old Champions League football next season.
Ed Woodward is also understood to have ended the Red Devils interest in taking Alvaro Morata to Old Trafford. After protracted talks over the back-up Real Madrid forward, Woodward has told the Bernabeu hierarchy negotiations are dead in the water.
Mino Raiola is Lukakus agent – and he represented deals for Paul Pogba, Zlatan Ibrahimovic and Henrikh Mkhitaryan, who all joined United last summer.
Pogba moved for a world record £89m and the fee for Lukaku will be in the top five all-time most expensive switches.
Paul Pogba and Romelu Lukaku share the same agent and are known to be big pals after holidaying in California together.
Mino Raiola is Lukakus agent and the super agent looks set to make a lot of money out of this latest transfer to United.
Paul Pogba and Romelu Lukaku spent the summer break hanging out in Los Angeles.
Mourinho has been desperate to land a striker before his squad re-convene for pre-season training on Saturday, ahead of the clubs flight to the US on Sunday for their tour of the States.
Lukakus 26 goals in all competitions for the Toffees last season was the most in 30 years at Goodison Park, since Gary Lineker netted 40 in their title-winning 1985-86 season.
This latest news will disappoint Chelsea fans, who had hoped to re-unite with Lukaku. He signed for the Blues from Anderlecht in 2011 before being sent out on loan to West Brom and then Everton.
Lukaku has been on holiday in California this summer, where he hung out with Paul Pogba and the pair partied around Los Angeles.
Romelu Lukaku factfile Romelu Lukaku was born on May 13 1993 in Atwerp, Belgium He began his youth career at Repel Boom before spells at KFC Wintam and Lierse Anderlecht was Lukakus first club as a senior player in 2009 After three years at the Belgian club, Lukaku was sold to Chelsea Lukaku struggled to break into Jose Mourinhos first team and was loaned to West Brom in 2012 A loan spell at Everton followed before being sold for a club record Lukaku has scored 53 goals in 110 appearances for the Toffees Want Lukaku in your fantasy football team? Sign up here.
Romelu Lukaku has been spending time relaxing in California ahead of the new season.
Romelu Lukaku had this picture taken on Santa Monica pier in Los Angeles. They also spent time in Miami last summer, before the Frenchmans world-record switch to United.
Lukaku turned down a record contract offer from Everton in March. He said at the time: I dont want to stay at the same level.
I want to improve and I know where I want to do that. Despite the clubs efforts to keep him, Lukaku is fiercely ambitious and has a tremendous goalscoring record.
At just 24, his goalscoring rate is on course to beat that of Alan Shearers 260 during the England hitmans career at Southampton, Blackburn and Newcastle.
I dont want to stay at the same level. I want to improve and I know where I want to do that.
Lukaku added: Everton as a football club has a great history, but the future has to be written, you get me?.
We always talk about the teams of the 80s and 70s and it was great, but we we want the fans talking about. No disrespect but you want to remembered as well.
You want to be remembered by winning trophies at the end of the day. So instead of living in the past, you have to think ahead.
You have to think how this club has to grow, how it has to improve, which player does it want to bring in so you can challenge for the big trophies.
I don't know what the board's plan is, but there were some players I knew the club could have got and they didn't, and they're playing in this league. I am not saying names, but they are doing well.".
Best buddies Paul Pogba and Romelu Lukaku make seriously cool poolside video in LA. Everton striker Romelu Lukaku with a fine brace against Leicester.
