A little calculator problem

[bijan311]

OK so everything compiled, BUT when it is linking to the .EXE it gives me this error

C:\Program Files\CodeBlocks\MinGW\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\include\c++\3.4.5\bits\stl_algobase.h:(.text$_ZN10calculatorD1Ev[calculator::~calculator()]+0xb)||undefined reference to `vtable for calculator'|
