line 17: break;

./a.out a <linedata

You are passing as 'a' as a parameter, and redirecting the standard input to the file linedata. However your program does not use its parameters, and does not read from standard input.

while( not infile.eof() ){
  infile.get(letter);

You don't reach eof until you try to read it. So it will be too late.
Change it to while( infile.get(letter) ){
