What's going on guys. This is bucky and your third c plus plus
0:03
tutorial. in this tutorial I want to go over a little more about printing
0:07
text out on the screen. now in the last saw earlier remember that we could use
0:12
especially think I'll see out
0:14
which is technically called ALP object and the less than less than sign which
0:18
was called
0:19
the stream insertion operator too proud tax on screen in
0:23
the way we did this is the added double quotes after and whatever we printed out
0:28
instead of course a good boy II love
0:31
bacon wherever we put inside those double quotes
0:34
which is proud on-screen Sophie go ahead and rebuilding her on this
0:38
we saw boy I love bacon re on-screen
0:42
simple enough but now what I want to go over is
0:45
just a little more about see our in I just want to make sure you guys
0:49
understand how it works
0:50
so each function is made up of these things called
0:54
statements and typically people per one statement
0:57
per line of code I remember all statements and with some icons
1:01
so say we wanted for now something else on screen well you to rate CL
1:05
less and less than and great something out psych
1:09
and cam just like that so you might be thinking RI I gotta feeling nine artists
1:14
can do
1:14
on the first line is going to bring down boy I love bacon and on the second one
1:18
is going to bring out and am because you know
1:20
that's how it appears in our code so that's what it's gon do
1:23
but we go ahead and donor on this it says boy I love bacon and ham
1:28
all on the same line of code every scratching their heads in RA
1:32
why exactly does it do that to rescind it does that be
1:35
is because when you're using this thing called see out
1:39
it's called printing out into a stream
1:42
and it pretty much takes all your characters imprints
1:46
now in the same stream so whenever this stream is done
1:49
you're not telling it to move to a new line you're saying
1:52
print out these characters and then stop rate the and assign
1:57
so then the stream starts printing out an again you not telling and you were to
2:02
move to a new line
2:03
computer programs are very picky and they need to be told
2:06
exactly what to do so in order to move to a new line
2:10
we need to add a special symbol I guess you would say
2:15
and the symbol is this for small you need to add another extreme insertion
2:19
operator
2:19
and you can go ahead and write Ende L
2:23
what this means is and line and now
2:26
when we go ahead and build and run it check what happens
2:30
Iran's boy I love bacon and then Iran's
2:34
en ligne an before your stream insertion operator would be right here
2:38
but now city said en ligne a go-ahead and and sis line
2:42
in it moves it to annex line so basically all you have to remember is
2:46
anytime you want to move to a new line use the character
2:49
and L which is code word for and line
2:52
now ever say nah right that's easy enough to remember
2:55
so let me go ahead and show you something that might be even easier for
3:00
you
3:00
inside your quotation marks if you go ahead and add
3:04
backslash an this is basically the same
3:08
is adding a new line backslash an
3:11
is the code I guess at all is code
3:14
for go to a new line so now it's gonna say boy I love bacon
3:19
and then it's going to come across the sink cut back slash and its can say hold
3:23
on
3:23
what is the specs ascent 00 I know what is
3:26
it's a simple to move to a new line so this is it
3:30
basically just an alternative way to move to new lines
3:33
the only difference is when and L you need to add
3:38
another insertion operator and then I and L right there
3:41
with the new line you rate it inside the quotation marks because
3:45
it gets interpreted and different kinda way so let's go ahead and build run this
3:48
and just verify that yep boy I love bacon
3:52
new line and Pam so again
3:55
like I said whenever you want print text on a new line you have to be very
3:59
specific worshipers poss
4:01
and tell you exactly what to do and you can do this
4:04
either using the NL or the new line
4:07
echoes inside the quotation marks so aside from this you might think
4:11
re: so I print this out and I got
4:14
this on next time but what if I wanted a blank line in between these two
4:18
well all you have to do is our new line newline
4:22
and then we go ahead and you going to run this ok say re:
4:25
boy I love bacon newline newline
4:29
and then a printed out and ham simple enough
4:32
pretty kojai and I guess one other thing I can show you is
4:35
if you go ahead and do see out
4:38
insertion operator arm you can do things like this
4:42
boy newline II in line
4:46
love newline makin
4:50
newline so you know you're not only limited to
4:53
you know one new line purse they mean you can have multiple new lines
4:56
on in a single statement so now it says
5:00
boy II love bacon pretty co-op
5:03
so that's all the basics I wanted you guys restore again
5:07
I one ish stress how to print out tax on the screen
5:10
and also the stream insertion operator
5:14
it's basically this each stream insertion resumes
5:19
its printing now wherever the previous one stop so if you want to move it to a
5:23
new
5:23
line you need to use one in these new line symbols either an L
5:27
or new line so that I have three guys in the store 0 now he should be a pro at
5:32
printing text on the screen
5:33
so you know we're not ready to I on what this program and sell to Microsoft yet
5:38
by hey
5:38
it starts up yes watchin if you have any questions got my life said in a bus in
5:42
dot com
5:43
and ask me on my forearm so think ASR watchin and IR
5:47
I guess I see next video
