encoding - Difference between double and single quotation marks in fortran?

Question

I'm just starting out on Fortran and am confused with the usage of double vs single quotation marks.

Answer 1

They are equivalent. There is no difference in their usage.

You can employ this to print one of the quotation characters:

print *, "'"

print *, '"'

prints first ' and then ".

Note: You can also use two quote characters in a row to print one:

print *, """"

print *, ''''

prints first " and then '.
