26      for (i = 0; i <= 19; i++) {
27        j = (responses[i] - 65);
28        if(responses[i] == answers[i]) {
29          numcorrect++;
30          counter[i][j]++;
31        }
32        else
33          counter[i][j]++;
34      }

should have been this:

     for (i = 0; i <= 19; i++) {
       j = (responses[i] - 65);
counter[i][j]++;
       if(responses[i] == answers[i])
         numcorrect++;
     }

They do the same thing, if something is in both loops, it doesn't need to be in either (i.e. it should be outside the loop). I should have exercised DRY.
