Also you are declaring a dynamic 2d array incorrectly by the look of it. Also a 2d array is array[x][y] not array[x,y]

Increase the verbosity of your compiler.

My compiler gives two errors.

Line 83:

		space SpaceGroup[];

[Error] ISO C++ forbids zero-size array 'SpaceGroup' [-Wpedantic]

In addition there are several compiler warnings, which are as already stated due to the incorrect use of the 2D array.

thanks I will try and see if it works with me
