What you have should work, unless I'm too tired to see a problem. Another way to write it would be

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
inData.open(fileName.c_str()); 
 
for (int i = 0; inData>> T[i]; i++)
  ++size;
inData.open(fileName.c_str()); 

for (int i = 0; inData>> T[i]; i++)
  ++size;

have you got any more code as if there is a problem you might need to show us the whole program. there is a good fstream tutorial on the site that can solve problems...

Im not entirely sure but my RLE compression / De-compression snippet MIGHT have file -> array code, but I think I performed the routine "on-the-fly"....
