In a professional environment, the result will be "go back and fix
the code, then we'll look at it".

The assignment is equivalent to

    c = a++ + b;

due to the "maximal munch" rule (the same rule that makes "a+++++b"
a syntax error rather than "a++ + ++b").  The code is badly formatted
and difficult to read, but there is no ambiguity.

I'll assume that's enough to tell you what the code does.  If not,
feel free to ask.
