I'm trying to compile my code and keep getting his with this error:
Error 1 error LNK2019: unresolved external symbol "class std::basic_ostream<char,struct std::char_traits<char> > & __cdecl operator<<(class std::basic_ostream<char,struct std::char_traits<char> > &,class iOrder const &)" (??6@YAAAV?$basic_ostream@DU?$char_traits@D@std@@@std@@AAV01@ABViOrder@@@Z) referenced in function _main C:\Users\on3m1_000\documents\visual studio 2013\Projects\Assign4\Assign4\a4main.obj Assign4
I'm totally unsure as to why this may be happening. The only thing I see in that error that looks even remotely like it's in my code is iOrder. If anyone can help give me any ideas as to why this is happening that would be great.
