2d array using txt file

herculas (1)
so i have an assignment part as follows:-

Complete the class CAI:
Write the definitions of all the member functions, the
constructors and the de-constructor. In case of path finding the map is a 2D array and therefore you should allocate dynamically a 2D array in the constructor, in case of sorting 1D array is required. Also make sure that you de-allocate the memory properly in the de-constructor. The map or the numbers for sorting should be loaded from a text file. An example is provided both for path finding and sorting.

the .cpp code is as follows:-
