Write a program that reads text from one file and writes an edited version
of the same text to another file. The edited version is identical to the unedited
version except that every string of two or more consecutive blanks
is replaced by a single blank. Thus, the text is edited to remove any extra
blank characters. Your program should define a function that is called with
the input- and output-file streams as arguments. If this is being done as a
class assignment, obtain the file names from your instructor
