I am in a C class. Professor wants us to use Visual Studio 2013 as our IDE. I submitted mine with the follow feedback from him:

"Do not use

Error 1 error C1083: Cannot open include file: 'stdafx.h': No such file or directory c:\users\professor\desktop\++grading\145\school\ch2_2.cpp 5 1 Grading

--------------------

Error 1 error C2061: syntax error : identifier '_TCHAR' c:\users\professor\desktop\++grading\145\school\ch2_2.cpp 13 1 Grading

2 IntelliSense: identifier "_TCHAR" is undefined c:\Users\Professor\Desktop\++Grading\145\school\CH2_2.cpp 13 22 Grading

--------------------------

_TCHAR* is not ANSI standard.nor is _tmain.

------------------

I was able to open your files but not run them."

Literally have no idea what he is asking. I sent him a reply and he's ignored me for the last few days. Feels bad..

My code can be found :

Code runs fine on Linux.
Would try and make a new project. Probably some issue with Visual.

Just a note that your program does not handle floats.
You should ask the user for natural numbers only.
