 ifstream ptext ("ptext.txt",ios::binary);
 ofstream enc ("encrypted.txt",ios::binary);

  string result(15, '\0');
  ptext.read(&result[0], 15);
  result.resize(ptext.gcount());

  encrypt(result,keysched,encryptedblock);

for (int a=0;a<4;a++)
    for (int b=0;b<4;b++)
        enc << encryptedblock[b][a];


How efficient is this for loading in a file 15 chars at a time and then outputing a 2d array to another file?
