C Language Tutorial on fgets() Function for Beginners Session 20 Video Lecture | Basics of C Language - Fundamentals of Programming - Software Development

the last session that is session 20 in
the c language f gets function to read a
line of text from the file gets and gets
a variable and get some name so this is
a function which gets the particular
string from that particular file where
it is we have seen in the last example
which is to get a particular so now then
this program if you save writing some
text to a file this is a file pointer
and I am trying to open the file Kiran
dot see if it is not available I will
create it and now i will say string
length gets off s this is what gets us
and puts water i got into the very array
SI will be printing it on the screen s
along with a pointer after that a
newline character finally closing that
particular file so subtext like and so
on this will be saving some some text
like all these things ultimately no text
so that is the end this all has been
saved in eid rice kiran dot c folder
which I will open it now going for ed
drives Kiran dot C is a file so this is
the file in which i have placed all my
data just now if I this is how f gets
inputs works similarly puts as the way
we are getting a character by character
we are putting it on the file the
character by character fwrite and afraid
functions to read and write the record
structures we have two functions F right
ampersand e-commerce I Sophie
one gamma ffp afraid these are the
functions which reads and writes to the
function command-line arguments the
arguments that we pass on to Maine at
the cover from tour called command-line
arguments the syntax is main int Archie
comma character arc we wear our see
holds a count of the argument and argue
holds the base address of the strings at
the command prompt command we have to
copy the contents of the one file into
the other file at the command copy this
is the way we copy but before that if we
take up an example of command prompt see
this is a program which can print
program name the program name is no name
11 dot CPP that is printed on the screen
so it is C colon Kieran Kieran and
receive files no name alone dot cec is
our address so it gives the particular
file name where it has been stored and
that is given in the RV 02 block so the
Argosy and arguing gives you the side
current program name and all those
things go for we have to copy the
contents of one file into another file
at the command prompt file copy PR 1 dot
CP R 2 dot C then our feud contain three
ry 0 would contain base address of the
string file copy are we one would
contain base address of the string p1
dot C and r2 would contain base address
of the shrink PR 2 dot C so we are
saying three terms in this and those
three is represented by C in the RV & 0
the block file copy first look we r 1
dot c second block PR 2 dot see this is
what happens in the command line prompt
when we go for saying come arguments in
a.c language and also the differences
between all the reading modes we have in
our it creates only
it reads not creates it reads only the
file which is which exists it cannot
create a file this is about are coming
to W it creates the file if it not if it
does not exist does not exist and then
it reads and the other is a mode append
mode it creates the file if it does not
exit and then reads it so these are the
different types of modes we have in the
file concept so our if the file is there
it will only rear read that file if the
file is not that it cannot read it and
so it says the appropriate error on the
screen coming to W if the file is not
there the W mode can create will create
the file and then it will write the text
on that and later on if we retype
anything that is lost the previously
written code is lost coming to append
mode you and it creates a file it reads
the file and it also continuous writing
a particular file so these are the
topics will be seeing in files concept
under C language this with this I can
say I can put an end to the C language
