Explanation / Answer

The problem is in the overloading functons of GetInputFile.The same applies for the GetOutputFile.

There are two variants and they only differ by return types, one has a return type of int and the reutrn type of the other is ifstream.So, the overloading isnt possible until the parameters vary too.On fixing that, the overloading will take place.
