Subject: Backslash substitution question

I'm having trouble with backslashes and I don't know what is wrong.  I
can't seem to write and expression that will evaluate to a string
containing a single backslash character as in "\".  It seems that "\\"
in Ruby evaluates to "\\" not to "\" as I would expect.  Below are a few
things I've tried.  If anyone could send back a quick answer it would be
much appreciated.

res = "c:/foo/bar".gsub(/\//, "\\")   # -> c:\\foo\\bar
res = "c:/foo/bar".gsub(/\//, '\\')   # -> c:\\foo\\bar
#res = "c:/foo/bar".gsub(/\//, "\")   # -> syntax error - unterminated
string meets end of file
#res = "c:/foo/bar".gsub(/\//, '\')   # -> syntax error - unterminated
string meets end of file
res = "c:/foo/bar".gsub(/\//) { "\\"} # -> c:\\foo\\bar
