00:00:02

full course channel, go down, and more,

00:00:05

in this video you will learn the types

00:00:08

of data, how to define variables in themselves, and

00:00:11

be more, you are in the full course, and you will

00:00:14

see all types of data, both

00:00:15

integer stringhi and use all this

00:00:17

front here in this video declare

00:00:20

variables you will also learn in this

00:00:22

video but you don't see if you write activate the

00:00:24

bell leave your like share there is

00:00:26

a playlist here below the

00:00:28

complete course so you can do it in

00:00:30

sequence so let's go straight to see some

00:00:32

types of data in c and c is more from

00:00:35

now on we saw the

00:00:38

previous video, remember that every program

00:00:40

in being he bought from basically

00:00:42

a header, free libraries and a

00:00:46

man function, ok, the whole program you will

00:00:49

have to have this structure ok and we

00:00:50

had already done it in the previous video and then I

00:00:53

debuted ok we used namespace std

00:00:55

so we could activate the functions

00:00:58

herald and l

00:01:00

and intimem return 0 ok let's go then

00:01:03

talk about the data types in your what are

00:01:05

data types are the information that

00:01:08

you will store in your program, okay, these

00:01:10

are the variables that you will store

00:01:13

some information perfect so how to

00:01:15

declare a variable also and be the

00:01:18

first item you put its type the

00:01:20

name of the variable and its value so

00:01:23

let's talk start talking by the

00:01:24

int type the int type what is the int type it

00:01:28

will store integers ok integers

00:01:30

are numbers that you know in everyday life

00:01:33

10 15 27 without are all

00:01:38

integers ok it is the number that has

00:01:42

decimal places it is not a number

00:01:45

perfect integer 3.14 value of pi is not an

00:01:49

integer perfect every integer

00:01:50

any set of numbers that you

00:01:53

will work with on a daily basis so let's

00:01:55

create a variable I'll talk next

00:01:57

hot number just a number

00:02:00

one ok, that way I've already declared one

00:02:03

variable to be int number, from

00:02:06

now on the variable number exists, it is

00:02:10

defined and it will contain an

00:02:12

integer, there is another way to declare it,

00:02:14

also passing a value in which number is

00:02:16

equal to 10, for example, ok, it is another

00:02:20

way of declaring integer variables,

00:02:22

cool, I I don't know from this moment

00:02:25

that I have this number I can send

00:02:27

an audio, right?

00:02:40

let's run it so

00:02:43

we can see what the number is and put the number

00:02:46

we define up here so

00:02:48

from now on you will have a

00:02:49

variable allocated in the program and what

00:02:53

happens it will allocate a piece of

00:02:55

memory ok some dances to store

00:02:58

this variable are you

00:03:00

and you already have a variable defined like take

00:03:02

a look here at high power the number is

00:03:06

10 look how cool it is so here you have

00:03:09

even done one showing how you will show

00:03:11

this variable perfect all the

00:03:13

languages derived from and it follows a

00:03:16

little similar, right? you see it's a java

00:03:18

script for example java follows very

00:03:21

similar the takes the one dollar in this

00:03:23

variable it's the dollar something but it

00:03:25

follows this same line of defining

00:03:28

variables cool let's see now

00:03:30

another type of data in being more more this is

00:03:33

worth it in and and us be more more is the base

00:03:37

is I don't know but it's also worth I don't know

00:03:39

more but it's the definition and you out just be

00:03:42

more more okay so number inter

00:03:45

inter to store integers ok it

00:03:48

has none none modifier in it it

00:03:51

counts negative and positive numbers ok

00:03:54

now let's create a second one now

00:03:56

if I want to store the value of pi, right

00:03:58

three points 14 and 15,

00:04:00

the step we will define a variable

00:04:02

like flut is the name front sells

00:04:06

floating point so three points 1415

00:04:09

means that this point floats right,

00:04:12

if you multiply by 101, for example,

00:04:15

it comes here by 0.01 and comes here,

00:04:18

so it can vary, right, float in the

00:04:21

number, so this is a floating point, ok,

00:04:23

so I give the name of the variable, right, flute,

00:04:26

I'm going to call it a point, okay? dot

00:04:31

underline in floating color ok equal to

00:04:38

3.14 15 so here, defining a

00:04:40

variable in being a second

00:04:43

flut type variable is always the type, the name of the

00:04:46

variable and its value it is not necessary to

00:04:48

specify at this point the value

00:04:50

is still as we saw so south

00:04:53

floating point equal to 3.14 15 I can call

00:04:57

it changing her name for dinner pin, right,

00:04:59

ok

00:05:00

and remembering that if it is case

00:05:02

sensitive, it's like lowercase pi, it's

00:05:05

different from capital pi, okay, so

00:05:09

I'm going to put a as perfect pe, the name of the

00:05:12

variable pe variable number has some

00:05:14

rules, right, if it can't, therefore, it can be a

00:05:16

special character in the variable type sink

00:05:19

asterisk I didn't have myopia tic-tac-toe,

00:05:21

that's not valid, okay, okay, name are

00:05:24

letters and numbers where scor

00:05:26

variable number in c top from deep 3.14 15 if

00:05:31

I want to show this if audio, right smaller

00:05:34

smaller me

00:05:35

and I'm going to put here double quotes the

00:05:40

value of pi is smaller smaller fi ok here

00:05:47

I want to plus online okay I want to

00:05:49

skip a line I'm going to do it without skipping

00:05:51

a line so you can see how

00:05:53

it works ok so the value of pi and p name of the

00:05:57

variable there so let's run this one

00:05:59

will just run so we can see this new type

00:06:02

of variable floating point or front is

00:06:06

here look how cool it is the number is 10 here

00:06:10

is the value of pi is 31415 replace your

00:06:14

name bath from there he what he did

00:06:16

he put everything here oh he doesn't skip

00:06:18

lines anymore oh everything is a bit stuck together,

00:06:20

you see that's why we

00:06:22

used underlining to separate the rest of

00:06:24

mine, which is buggy, right? and for the

00:06:26

rest of the perfect bass line it was

00:06:28

still bang if you are in the

00:06:30

directory for example if I give a loaf of bread

00:06:33

so I can put it in the directory a and there is

00:06:34

his name here

00:06:35

and I will have it today, you can see I have a

00:06:37

roll in the world point of say if I call

00:06:39

point slash hello world it will point dese

00:06:44

it will execute it will be clean

00:06:46

for me look the number is 10 the sink value

00:06:48

3.14 if you want to call the executable

00:06:51

it is the program we made it is here in

00:06:54

debug it has a few more things

00:06:55

so I'm going to add edilaine too

00:06:58

and it's ok remembering that ml is part

00:07:02

of the std namespace they will continue so

00:07:04

one more type of variable now in being

00:07:07

more more and you're replanting not being

00:07:09

how much I don't know anymore

00:07:12

and remembering that the type both int type

00:07:15

and flaut type it will occupy 4 bytes

00:07:19

of memory to allocate the

00:07:22

perfect variable so there is a size and

00:07:24

memory is 4 bytes to allocate this

00:07:28

variable I will if you need a

00:07:30

larger number we are talking here it is

00:07:31

a number extremely large, right?

00:07:48

count a floating number, so if for

00:07:50

example you need a number, the

00:07:54

iel number is a very large number, it will be 9,999

00:08:00

very, very, very large, I have

00:08:03

double, ok, it's not big here,

00:08:06

in fact, I'm going to do a better one, I

00:08:07

'm going to leave this number and move the point

00:08:10

here, okay, I'm going,

00:08:12

this is the numbers that will actually be released

00:08:15

municipally to rent double, it's the same

00:08:18

thing here, so if out

00:08:22

the smallest, the giant number is smaller,

00:08:30

better, smaller, larger number, and he who

00:08:35

is already training a little, but your

00:08:37

audio, we'll run it here for us to see,

00:08:40

okay, so he already showed his mother that today

00:08:41

a notation that is one is one to the power of

00:08:45

plus 36, okay, we're going to use a note

00:08:48

because it's the number, it's actually going to be

00:08:51

saved like this, okay, okay, there's already a

00:08:54

note then one to the power of plus 36 ready

00:08:57

due to the size of the number ok

00:09:01

let's talk we have a very

00:09:03

important type I don't know now ok it's a

00:09:06

set of one character just ok I'll

00:09:09

pull it now so bye ok letter you

00:09:14

can define it so you you can

00:09:15

put any character here, thiago

00:09:17

will allocate from 0 to 255 beats, ok, so

00:09:21

any letter

00:09:22

a car letter equal to ok, so let's

00:09:25

put it here, ok also ducharse audio

00:09:28

same thing you are loud if audio smaller smaller

00:09:33

the letter is

00:09:37

the smaller smaller letter letter okay nl perfect

00:09:46

so here it will allocate a set of

00:09:49

1 byte for a perfect pull is the basis

00:09:52

of the string quilt air in being cool so

00:09:56

what I'm going to do as it's getting a lot

00:09:58

I'm going to take it and add it to

00:10:00

the one already used then leave one more

00:10:02

always highlight something new.

00:10:21

c the language is a

00:10:25

string is a set of characters is a

00:10:27

network characters is a list of

00:10:29

characters okay so these are the

00:10:31

basic types some basic types of data in

00:10:35

perfect c you do be more but it changes a

00:10:39

little when we start to

00:10:40

working with stringhi become stringer a

00:10:43

set of chars ok so several

00:10:45

characters will form a string several

00:10:48

letters together form a string type

00:10:50

so what am I going to do for you I am going to

00:10:52

save this code here and I am going to make

00:10:56

a code in C so you can see how

00:10:58

it's strings and then I'm going to write a

00:11:01

code in C++ so we can see the string

00:11:03

in both, okay, so I'm copying it

00:11:05

here and we're going to put a program in C

00:11:08

now so we can see it from the stream,

00:11:11

ok, these types are valid, I don't know and

00:11:14

I don't know what else we've already seen, you know,

00:11:16

include std,

00:11:17

ok, perfect in an instant, there, the intimate and

00:11:23

perfect voice, and I could sesc he wants the

00:11:25

divine code, another is inscribed, so

00:11:27

when I define a variable, it's supposed to be

00:11:31

strings, and the language is ok you will

00:11:35

define it by name ok

00:11:38

its size let's go because the name is 30

00:11:41

right and its value is the same for example

00:11:43

davis from now on

00:11:46

and I have a stringhi variable

00:11:51

well so let's see how to define strings

00:11:54

right in the c language ok how are you going to do

00:11:57

the language it will be stringhi it will be a

00:12:00

set of characters find a list

00:12:03

of characters an array of characters

00:12:04

how do you define this take the name of

00:12:08

your stringueta you will define

00:12:09

its size here and let's go because it was 30

00:12:12

it's name a variable with 30 karsoke

00:12:14

equals open double quotes is its value

00:12:19

so I'm here in case put davis is

00:12:21

set close name is a string of 30

00:12:25

bytes and memory is 30 chars with the name

00:12:29

deivila is receiving davis perfect

00:12:31

languages and I will show you the

00:12:33

print f is the printf function how it

00:12:36

works double quotes ok the value of the

00:12:41

name is for example when you printf

00:12:46

you do what percentage is this what is

00:12:49

percentage stringhi is everything how

00:12:51

and what is the value of string percentage f and

00:12:54

put a comma after the variable

00:12:56

name for example semicolon at the

00:12:58

end so show you better the

00:13:01

printf function you will go through because

00:13:03

you are printing it is and the variables with a

00:13:06

comma after it are and this will

00:13:08

replace the string variable the

00:13:10

current price is if at the time of printing

00:13:11

replace this percentage with the

00:13:14

variable ok so this way of defining

00:13:17

strings in the c language ok we'll

00:13:20

see if it runs more so we can see

00:13:23

debug the value of the name is davis look how

00:13:28

cool perfect here didn't put bahraini if

00:13:31

you want to put it I can put a

00:13:32

slash right, now it's language,

00:13:35

come on, let's remember that for whoever you are, I

00:13:39

have to have English dst then the dot

00:13:42

h and this way define strings in the

00:13:44

language c

00:13:47

the value of name is deivison ok ok, that's

00:13:50

right, cool, right now we're

00:13:54

going seeing how to define strings is more

00:13:57

perfect, so I'm going to return the code to

00:14:00

be more cool because I'm

00:14:03

showing both languages, it's all in

00:14:05

you when you

00:14:06

learn the base, right?

00:14:11

which was already there I debut now

00:14:14

because this is more namespace std

00:14:15

cool the mogi to define string in c

00:14:19

++ now that he previous example is

00:14:21

there is a type in ser more more right to

00:14:24

resolve this called stringhi so

00:14:26

england

00:14:28

the stringer is from now on we

00:14:31

already have these types of string prefect of

00:14:34

page exactly stringhi name equal

00:14:38

name semicolon ok so

00:14:42

from now on the other thing strengh double quotation marks

00:14:45

ok it's a little extra detail here

00:14:47

for you it's not equal to I do

00:14:49

n't know what else, but seraut, not

00:14:53

the string type, it has already been encapsulated, right,

00:14:55

this array, leave it, has already been

00:14:57

encapsulated, no, strange type, right, the name

00:15:00

is

00:15:01

the smallest, the smallest name, it's better to fill it, it's a

00:15:06

way of defining it, destroying it, it's

00:15:09

more, it's include stringhi the header of

00:15:13

stringueta streaming library in the

00:15:15

string name equal in double quotes is

00:15:19

the name and if out the name that we have already

00:15:23

seen let's run

00:15:27

it is a because my everything right the name is

00:15:32

davis cool so then you have a way of

00:15:33

defining half stream So,

00:15:35

remembering, we saw type int, there are

00:15:38

integer values, flute, floating point,

00:15:40

right, a value that has a point, double,

00:15:43

which is for larger values,

00:15:45

requires flow to four decimal places.

00:15:47

From here, the precision of the double is

00:15:50

ten decimal places. from the point,

00:15:52

there's a big difference here, they take up 4

00:15:55

bytes, which occupies 8 bytes, ok, there's a

00:15:58

set of zeros, 235, right, the

00:16:01

ascii code here will have letters and numbers, ok, and

00:16:04

spring, that's what it's a

00:16:06

tea network and it already has more

00:16:09

stringhi type, if you can use the direct

00:16:12

stringher, of course, always using the

00:16:14

implant, right stringhi, the variable equals

00:16:18

double quotes the name you want and

00:16:20

your audio in it is here, this example is

00:16:23

very cool from

00:16:25

this point onwards, it's cool, right?

00:16:40

bringing it according to the next videos,

00:16:41

you can change these types of

00:16:43

variables and there are some other types of

00:16:45

pointers, all of this that he will see

00:16:47

in the next videos, you want new ones,

00:16:49

write now, don't forget, activate the bell, leave a

00:16:51
