was going guys and this Bucky with your third c plus plus
0:03
tutorial. And in this tutorial I wanna go over a little more about printing
0:07
text on the screen. Now in the last tutorial you remember that we could use
0:12
that special thing cout
0:14
which is technically called 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 this double quotes. "boy I love
0:31
bacon" wherever we put inside those double quotes
0:34
which is print out on the screen. So if we go ahead and rebuild and run this
0:38
we saw "boy I love bacon" right on-screen.
0:42
simple enough. but now what I want to go over is
0:45
just a little more about cout. 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 semicolons.
1:01
so say we wanted for now something else on screen well you would write cout
1:05
less than less than and get something out like
1:09
"and ham" just like that. So you might be thinking, alright, I gotta feeling I know what this is gonna
1:14
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 do.
1:23
but we go ahead and run this. it says boy I love bacon and ham
1:28
all on the same line of code. and if you are scratching your head, alright,
1:32
why exactly does it do that. the reason it does that
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 them out
1:46
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 end of this line.
1:57
so then the stream starts printing out and 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 ENDL
2:23
what this means is end line and
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 an before your stream insertion operator would be right here
2:38
but now since you said in line and go-ahead and ends this line
2:42
in it moves it to the next 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
ENDL which is code word for and line
2:52
now if your are saying alright 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 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 this thing called back slash and its can say hold
3:23
on
3:23
what is this backslash n. I know what is
3:26
it's a symbol to move to a new line so this is it
3:30
basically just an alternative way to move to new line.
3:33
the only difference is when ENDL, you need to add
3:38
another insertion operator and then write ENDL 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++
4:01
and tell you exactly what to do and you can do this
4:04
either using the ENDL or the new line
4:07
echoes inside the quotation marks. So aside from this you might think
4:11
alright, 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 write new line new line
4:22
and then we go ahead and you going to run this, ok say alright
4:25
"boy I love bacon" new line new line
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, uhm, you can do things like this
4:42
boy newline I in line
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
um 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 you guys for this tutorial.
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 ENDL
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 starts up yes watchin if you have any questions go to my website newboston
5:42
dot com
5:43
and ask me on my forum, so thank you for watchin and I'll, uh,
5:47
I guess I see you in the next video
