FAQs on Fortran Programming Tutorials (Revised) : 016 : Printing Strings and Quote Mixing Video Lecture - Introduction to Fortran Programming (Basic Level) - Database Management
| 1. How can I print a string in Fortran programming? |  |
Ans. In Fortran programming, you can print a string using the WRITE statement. You can specify the string to be printed within quotation marks. For example:
WRITE(*, *) "Hello, World!"
This will print the string "Hello, World!" to the standard output.
| 2. Can I mix quotes in Fortran programming? | |
Ans. Yes, you can mix single quotes and double quotes in Fortran programming. Both types of quotes can be used to define strings. For example:
WRITE(*, *) 'This is a single-quoted string'
WRITE(*, *) "This is a double-quoted string"
Both of these statements are valid and will print the respective strings to the standard output.
| 3. How can I concatenate strings in Fortran programming? | |
Ans. In Fortran programming, you can concatenate strings using the // operator. For example:
CHARACTER(LEN=20) :: str1 = 'Hello'
CHARACTER(LEN=20) :: str2 = 'World!'
CHARACTER(LEN=40) :: concatenated_str
concatenated_str = str1 // ' ' // str2
This will concatenate the strings str1, a space, and str2, and store the result in the variable concatenated_str.
| 4. How can I print a variable along with a string in Fortran programming? | |
Ans. To print a variable along with a string in Fortran programming, you can use the concatenation operator (//) or the formatted WRITE statement. For example:
INTEGER :: num = 42
WRITE(*, *) 'The value of the variable is ' // num
or
WRITE(*, '(A, I3)') 'The value of the variable is ', num
Both of these statements will print the value of the variable num along with the provided string.
| 5. How can I handle special characters in Fortran strings? | |
Ans. To handle special characters in Fortran strings, you can use escape sequences. The most commonly used escape sequences are:
- \n for a new line
- \t for a tab
- \' for a single quote
- \" for a double quote
For example:
WRITE(*, *) 'This is a string with a new line\nand a tab\tand quotes: \'\'\"\"'
This will print the string "This is a string with a new line" on one line, followed by "and a tab and quotes: ''"" on the next line.

hello guys my name is Aaron and welcome
to my channel this series is a series of
tutorials on Fortran programming now in
the last tutorial we saw how to define
and use string and stress character
string and string arrays okay now in
this tutorial this is a slight extension
of it wherein we will explain you guys
has to how to print and use no single
course and multiple quotes inside state
inside statements and all now in Fortran
what by default
it allows the usage of both single
quotes and double quotes unanimously and
in a you can so you can kind of use them
in a proper manner for instance let me
just you know comment this line we don't
need this as of now okay so we just need
we need this this and and this line okay
let's say this and also we will need
these evil do you need these lines so
let me just it means group select them
all and and I just uncomment the lines
and uncomment the lines and similarly I
group select them all and I know
uncomment the lines okay so the thing is
if you want to assign a string or a
character to you know a variable to as
character a character variable or a
string variable you can use single
quotes and double quotes like this for
instance you can use single quotes and
write characters inside or you can use
double quotes to write it okay you can
use single quotes for string and strings
as well as car big characters and the
same way you can use double quotes for
the same purpose so it doesn't matter
but the problem actually comes when you
are using mixture mix and matching
single quotes for instance for instance
you guys look at this and if you guys
you know look at this this this this
sentence okay I'll come in this out for
a short period of time
okay you guys look at this this sentence
okay
I'd only matter
yeah so I will just come and all these
okay you comment all these yeah okay now
if you guys look at these two sentences
what it says is that it just it just
types my name is Aaron written in single
double quotes and the second line prints
my name is Aaron written in single
quotes so you are allowed to use your
honor to mix mix course unanimously
similarly suppose if I were to define
this character a equals x in sorry X in
C double course this again this again
works this again work so no problem in
that this is just an okay and move the
cursor alternate expression I simplest
that this is just an alternate
expression fine so this one throw any
error at all and now yeah these
sentences are perfectly fine just like
how we did here make a new single cost
double cost enclose strings no problem
but suppose I prefer to write this
sentence if I were to write the sentence
where it says he is my teacher he is my
friend's teacher now thing is he I said
I'm using a single code has enough
single code has an opposite of
apostrophe so if I were to write this
entire thing at single course okay it is
the genie I mean the compiler will throw
mean error because you guys notice that
a string gets terminated here so to
avoid that what you have to do is that
you have to write everything in double
quotes okay this this single quote
double power mix the mix and matching
helps a lot if felt a lot for instance
if you guys look at the seconds this
four sentence okay now I am writing I am
fine in double quotes inside an already
quoted sentence and this inside sentence
outer sentence is written in inside
single quotes so that I can write in
inside sentence in double
quartz as per my wish similarly
similarly in this in this Center in this
print statement over here the entire
statement is written in double quotes
whereas the inner part of it I am fine
is written in the single course as long
as one coated with sandwiched inside the
other code quote other type of code
you're doing fine
nothing to worry but there might be a
condition wherein you have to you have
to include both both the contents inside
the same kind of course for instance in
this in this sentence if I had to
instead of this double quote if ever do
you single course or not okay I'll get a
warning like this and I'll get I will
get a non string character so this might
be turn out to be problematic stew to
simplify that what Fortran does is that
it allows use this option called as
double single coating double single
coating so what it does is see in this
part of the sentence I write them within
double double quotes double double
quotes there by what this double double
quote says is that it mentions okay a
cancer of the next single core double
quote as a pie as a quote and ignore
this and ignore this when you come under
string Concord is doing a issues he take
this I take this as a character and go
along with it without any error and all
and the same thing can be replicated the
single quotes here I have written
everything all the entire sentence in a
single quote and this part of the
sentence in double single quotes and a
net again this also works pretty fine
okay now if I have to you know bring
this all up okay I don't need any of
these so I just comment this up okay I
comment this up okay yeah that will be
fine now if I just if I just compile
this I'm just getting a lot of warnings
because I haven't used any of these so
let me just comment this out
okay come on this out is compiled this a
fake no problem f9 build it and I fight
with the execution and there you have it
these parts get printed as it is with
the reading issues and if you guys
notice there's no difference between the
uses of double coated single quotes here
and they beside and also in this
sentence there's no difference there is
no there is no difference in using the
same suppose if I were to write this
entire thing write the entire thing in a
different manner I suppose like double
quotes like here and single quotes here
and single quotes here okay yeah I just
quit this up save this compile this
build this and execute this it works
just it works just fine okay
except that since I put a double quotes
here it's printing the double quotes
here if you guys can see okay so other
than that then we can accept the single
cause and double quotes can work
unanimously fine and this will be really
helpful this will be really helpful if
you guys you know want to put strings
within other strings and printing like
that like that sort of stuff okay now
that's all I have for you guys in this
tutorial and thank you guys for watching
see you guys in the next tutorial and
the next tutorials we look will jump
into some other interesting topics which
will be of you know little more of the
greater use okay thank you guys for
watching see you guys next tutorial bye
