Difficulties with my little C++ .dll

MJR94 (5)
I am editing one of my meshes in c++ form because of the benefits that it has to offer. However it is not that easy. I am kind of stuck. Here is my error and here is my .cpp.

1>.\AtlasA.cpp(53) : error C2143: syntax error : missing ';' before '}'
1>.\AtlasA.cpp(55) : error C2447: '{' : missing function header (old-style formal list?)
1>.\AtlasA.cpp(107) : fatal error C1004: unexpected end-of-file found

Thank you.

Your parentheses are are mostly inconsistent/incorrect. Your indentation doesn't help, it's supposed to help you see scope and where parentheses ought to be.
MJR94 (5)
My parentheses or brackets?
helios (17574)
Both, actually.

Apparently I am new at this, but I think I am making some progress. I got 2 errors.

.\AtlasA.cpp(35) : error C2470: 'line' : looks like a function definition, but there is no parameter list; skipping apparent body
1>.\AtlasA.cpp(104) : fatal error C1004: unexpected end-of-file found

Here is the new code.

i think on line 34, it's missing the terminator ';' at the end of the line if line is not a function. Otherwise if line is a function, then it's missing its parentheses?
MJR94 (5)
Thank you. I will try that and see what the result is.

Jesus Christ! This is a disaster!

I reformatted with AStyle. The comments describe syntactical problems.
