I am receiving the following errors with my code:
Error 3 error LNK1120: 1 unresolved externals c:\users\toking\documents\visual studio 2012\Projects\11.9\Debug\11.9.exe 11.9
Error 2 error LNK2001: unresolved external symbol "public: double __thiscall Package::calculateCost(float,double)" (?calculateCost@Package@@QAENMN@Z) c:\Users\toking\documents\visual studio 2012\Projects\11.9\11.9\11.9_main.obj 11.9
Error 1 error LNK2019: unresolved external symbol "public: double __thiscall Package::calculateCost(float,double)" (?calculateCost@Package@@QAENMN@Z) referenced in function "public: double __thiscall overnightPackage::calcCostOvernight(float,double,double)" (?calcCostOvernight@overnightPackage@@QAENMNN@Z) c:\Users\toking\documents\visual studio 2012\Projects\11.9\11.9\11.9.obj 11.9
This is my second semester of C++ and my first time using inheritance. I tried calling the functions similarly to how my book calls them, but all of the errors seem to be related to my derived classes functions. Any help is greatly appreciated.
