C++ How to resolve linker error 2005

[idesmaster]

Dear All,

For you who need to separate definition and declaration from StrategyInterface.h and TechnicalFunctions.h files, attached are those files.

Background:
if you have a large project, you will notice that your own 2 or more .cpp cannot have #include to above headers, similar to problem below:

Reason:
StrategyInterface.h and TechnicalFunctions.h files contains both declaration and definition. during compile it's fine, during linking you will busted.

Solution:
You need to keep declaration in .h files, and definition goes to new .cpp files. You have to separate declarations and definitions
I have attached the complete solutions.
