What's going on? This is Bucky. Your third C plus plus
0:03
tutorial and in this tutorial I want to go over a little more about printing
0:07
text on the screen. now in the last saw earlier remember that we could use
0:12
that special thing called cout
0:14
which is technically called the output object and the less than less than sign which
0:18
was called
0:19
the stream insertion operator to print out text on the screen. In
0:23
the way we did this is the added double quotes after and whatever we printed out
0:28
in these double quotes. "Boy I love
0:31
bacon". Whatever we put inside those double quotes
0:34
which is print out on the screen. So I go ahead and build and run this
0:38
we saw "boy I love bacon" right on the 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 and remember all statements and with semicolons
1:01
so say we wanted for now something else on screen well, you would write cout
1:05
less and less than and great something out like
1:09
"and ham" just like that. so you might be thinking alright, I got a feeling I know what this
1:14
can do.
1:14
on the first line is going to print out "boy I love bacon" and on the second one
1:18
is going to print out and am because you know
1:20
that's how it appears in our code so that's what it's gonna
1:23
but we go ahead and build and run this it says "boy I love bacon and ham"
1:28
all on the same line of code. If you are scratching your head and saying alright
1:32
why exactly does it do that. The reason it does that be
1:35
is because when you're using this thing called cout
1:39
it's called printing out into a stream
1:42
and it pretty much takes all your characters and prints
1:46
them out 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 right at the end of the line
1:57
so then the stream starts printing out an again. You're 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. First of all, you need to add another stream insertion
2:19
operator
2:19
and you can go ahead and write E-N-D-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
It runs. "boy I love bacon" and then it runs
2:34
in line and before your stream insertion operator would be right here
2:38
but now city said in line. and go-ahead and ends this line
2:42
in it moves it to next line. so basically all you have to remember is
2:46
any time you want to move to a new line use the character
2:49
E N D L which is code word for end line
2:52
now ever saying all 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 n, this is basically the same
3:08
is adding a new line backslash n
3:11
is the code, I guess at all it 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 this thing called back slash and its can say hold
3:23
on
3:23
what is this special accent. I know what it 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 "END L" you need to add
3:38
another insertion operator and then write END L right there.
3:41
with the new line you write 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 ham. so again
3:55
like I said whenever you want print text on a new line you have to be very
3:59
specific with C plus plus
4:01
and tell you exactly what to do and you can do this
4:04
either using the END L or the new line
4:07
that goes inside the quotation marks. so aside from this you might think
4:11
all right. so I print this out and I got
4:14
this on next line. But what if I wanted a blank line in between these two
4:18
well all you have to do is write newline newline
4:22
and then we go ahead and you going to run this. ok, say all right
4:25
"boy I love bacon" newline newline
4:29
and then a printed out and ham. simple enough
4:32
pretty cool huh? and I guess one other thing I can show you is
4:35
if you go ahead and do cout
4:38
insertion operator, um, you can do things like this
4:42
boy newline - I - endline
4:46
love newline bacon
4:50
newline so you know you're not only limited to
4:53
you know one new line per statement.  you can have multiple new lines
4:56
in a single statement so now it says
5:00
"boy I love bacon" pretty cool, huh?
5:03
so that's all the basics I wanted for you guys this tutorial again
5:07
I wanted to stress how to print out text 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 out wherever the previous one stopped. 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 END L
5:27
or new line so that I have for you guys in this tutorial and now you should be a pro at
5:32
printing text on the screen
5:33
so you know we're not ready to bundle up this program and sell to Microsoft yet
5:38
by hey
5:38
it start. Thank you guys for watchin'. If you have any questions go to my website theNewBoston

dot com
5:43
and ask me on my forum. so thank you guys for watchin' and
5:47
I guess I see next video
