How many data types in c | What is default data type in C?

 hi everyone welcome to coding idea

technologies this is fin woz
so in the last session so we discussed
about a character data type now in this
session we will see some of the examples
on a character data type so first we
will see write we are writing unsigned
character and signed character in the
form of circles right so here it is

What is default data type in C?

suppose if it is a signed character the
limits are minus 128 to Plus 127 all
these limits we are writing in a form of
circle because based on these circles
only now we will see how programs will
execute here it is so we are writing so
this is circle either positive value or
negative value counting starts with 0

What are the different data types in c?explain?

this is a starting point positive value
is counting in a clockwise direction
positive value is counting and here it
is the maximum value is 127 is 127
negative values counting starts to the
minus 1 minus 2 minus 3 and so on up to
minus 128 this is assigned character
this is signed character first we will
see the examples on a signed character

so same story in the Declaration of
variable if you are not specifying
whether the variable is assigned
variable or unsigned variable by default
it is assigned variable and next one
this unsigned circle also we are writing
just 0 to 255 and this is the circle and
starts with 0 1 2 and so on and so on up
to 255 255 so this is unsigned character

circular unsigned character circle so
based on these two based on so these two
circles so now so we are discussing all
the programs these two so one is the
sign circle and second one is a
and sign circle a simple program I will
write a simple program for example here
it is here it is we are including the
header file hash include stdio.h if you
want to clear the screen we can include
so that see when I would odd hitch also
but of course not required anyway we

How many data types in c

discussed and here it is directly I am
writing main function I am declaring one
character care variable name any name
you can give for example here it is a
character name CH I am giving character
name CH and what is the value any value
you can give suppose I am giving capital
a but remember one thing in any

programming language we are representing
characters by using single quotes by
using single quotes right here it is we
are printing the value printf printf so
how to print this character right here
it is percentage C is a format specifier
and we are printing the value CH we are
printing the value CH here it is
CH value will print in the location of
percentage

see sir suppose whenever we are printing
that CH value printf I am NOT giving
percentage see I am giving percentage D
but the variable is a CH only but the
variable is CH only here it will print
it has to print in teaser so what
integer it will printer CH contains a
variable so what is the variable capital
a right it brings what capital a so that
capital a corresponding ASCII value it
will print so capital a value

corresponding ASCII value is a 65 so it
will print the value 65 okay so this is
a simple program so on a character data
type first we are declaring one
character we are printing
character by giving percentage see and
we are printing the ASCII value by
giving percentage D so percentage D
means what it is an integer format

What is primary data types in C?

specifier so it has to print in teaser
sir--what integer it will print already
we discussed in a character system every
character is represented by a constant
integer value so this is the constant
integer value 65 so it will print the
value 65 okay so we'll see the next
program so some trick equations here it
is they will ask like this for example

character CH character CH so they are
storing for example 258 258 they will
stores or can be store yes of course we
can into character data type we can
store integers also sir then what
character will go on store right here it
is assigned character or unsigned
character means by default it is
assigned character by defer is assigned

character so it will count the value 258
first CH gets memory allocation CH gets
memory allocation and it has to store
the value 258 it will count 258 in
assigned circle see this is signed
circle this is signed circle and here
the range is minus 128 to 127 so
counting 258 starts here 0 1 2 3 4 and
so on like that it will keep on counting
this value is equals to 255 in the short
data type we discussed very clearly just

compare these two circles so that is why
I have written here write a 0 above
value is a 255 so 255 256 257 to 58
so 258 corresponding value is a 2 so in
the memory the value 2 will go and store
in the memory the value 2 will go on
store so here it is whenever we are
printing printf printf and here it is a
percent is d we are

printing ch value and here it is a
printf printf % is see we are printing
the CH value sir whenever we are giving
percentage D it is happy we can say that
easily it will print the value 2 it will
print the value 2 sir whenever we are
printing that percentage see what
character it will print sir that we do
not know right so here it is no need to
buy hurt that entire ASCII code right
what value it will print means some

unexpected value some garbage character
it will print an unknown character it
will print that is what 2 corresponding
unknown character it will print two
corresponding ASCII character what it is
that will print from the ASCII character
system okay

What is default data type in C?

so this is a bit freak equation right
they will ask in the interview on a
character data type okay
and now so we will see how to write a
program that if you input one character
it has to print that corresponding s Q
value in this program first time we are
working with a scanner function first
time we are we are reading information

from the end user in C programming
language okay see here the program is
write a program to display ASCII value
to display ASCII value of character to
display ASCII value of character so this
is a heading of the program so first
time we are reading right information
from the end user we are taking input

from the end user right how we are
taking input see here it is hash include
hash include stdio.h header file we
included a next one we are writing main
method directly and here it is I am
declaring one variable variable
character variable name any name you can
take just like the previous program I am
taking CH only now CH gets memory
allocation

these do not assign any value directly
please do not assign any value directly
because here it is my requirement is I
just want to read information from the
end user I want to read the input from
the end user while application is
executing that is my concept here it is
CH gets memory allocation at some
location now address is very very
important
this is address memory location address
so we're right CH gets memory allocation
so now here it is this is the console on
console first I want to print a message
so what is the console where you can see
the output and where we can give the
input so that is called a console black
screen right here it is so we are asking
clearly enter one character enter one
character that message I want to print

message is very very important right if
you do not print this message and
whenever you show that console output to
the end user what end user want to do
that they cannot understand okay so that
is a reason we need to provide some
information best example ATM application
whenever you enter into ATM Center a
clear information it will show please
choose one language insert your ATM card
insert your PIN number
insert how much amount you want to
withdraw please collect the cash please
collect the card information is very

very important how good you are writing
the logic is not at all matters right
how clearly you are providing interface
to the end user is very very important
as a developer remember so here so first
we are asking the message very clearly
enter one character printf the same
message we are writing here enter one
character enter one character so

whatever the message you have written in
the printf function so that will be
written on the console or not yes so
that will write on the console on the
console it will print that message enter
one character so that we have to read
right so first time so whenever they

What are the data types in C give examples?

will enter one character for example I
entered that character hash I entered
that character has any character you can
pass right so then automatically system
will print that as key value see that
hash we should collect into this
location into this location so here we
need to provide the memory address we
need to provide memory address how to
provide memory address who will provide
memory address so first time we are
using scanf function in a c programming
how many characters you want to read sir
i want to read only one character so
write one time percentage c format
specifier sir i want to read a ten
characters ten times you have to write a
percentage c but here it is only one
character so that we are collecting the
character address you have to provide

ampersand is the address operator what
it will return the address of or the
memory location of this character it
will return the memory address of this
character it will return okay so here it
is 2 0 4 6 it will return
so hash whatever the character you have
given in the console that will be stored
in to this location so hash will go on

store and of course not exactly hash
hash corresponding ASCII value will be
converted into binary and then the
binary value will go on store and now I
want to print printf ASCII value is
ASCII value is I am writing in the next
line ask you value is percentage D and
here it is what we are printing CH we
are printing this is clear we are
reading using scanner function surveyor
scanner function is available in stdio.h
header file only the standard

input/output dot H header file only that
scanner function is available and we are
reading into a location CH
in the CH hash is their hash is their I
want to print the ASCII value very
simple how to print the ASCII value
instead of writing percentage see you
please write a percentage D is enough so
here it is percentage D we are writing C
hich corresponding value it will write
the sir what is it ask you value 35 35
it will write write whenever you start
executing your program right on the
console it will ask the message very
clearly
please enter one character any character
you can enter plus - dollar hash any
character you can enter when you press
ENTER then automatically it will show
right so what is the ASCII value of that
character okay all these programs
practically once again I will explain
right here it is using the blue-screen
ide okay so this is how to print the

ASCII value of the given ASCII character
right sir can I print all the ASCII
character symbols at a time impossible
because printer function you have to
write 256 times so because how many
number of ASCII values are there 256
ASCII values are there can you write a
printer function 256 times in a single
program impossible case so that is why

so please wait up to control statements
concept some loops we'll discuss in the
coming concepts so there I will show you
very clearly how to print the ASCII
character set in a C language okay right
so thank you for watching so thank you
all for more articel
