Yesterday I wrote a program, everything was fine, it worked fine. Today I decided to finish something in it, as it turned out that now an error appeared there, although the code was not edited by the last “successful” launch.

Now gives such a mistake:

[Error] Expected Unqualified-id Before ‘{‘ Token (Into Maen Announcement).

Remove at the end of this line

// ====================== ====================================== \\

Two reverse inclined features to be so

// ====================== ======================================

And you all work 🙂

The reason lies in the fact that the symbol of the reverse braid (\ ) is a string continued symbol if it stands at the end of the line. All rows ending with the reverse oscitment (\ ), followed by a new string symbol immediately, are combined with the following line in the source file, forming logical lines from physical lines. (MSDN)
