i keep getting error messages when i try to build my program:
EmpType.obj : error LNK2001: unresolved external symbol "public: __thiscall SortedType::SortedType(void)" (??0SortedType@@QAE@XZ)
EmpType.obj : error LNK2001: unresolved external symbol "public: void __thiscall SortedType::ResetList(void)" (?ResetList@SortedType@@QAEXXZ)
I also get the same error for InsertItem,GetNextItem,DeleteItem,RetrieveItem,LengthIs
any help in understanding this would be a great help
here is my code:
