  One small problem with this code is that no space is allocated for the
strings.  fscanf expects a pointer to an array of char that is large enough
to hold the string and a \0 delimiter.  So either you would add a malloc 
somewheres or maybe set up the data_array to be a 2D array
  [11][MAXSTRINGSIZE] where is MAXSTRINGSIZE is your expected max string size.
