Thread: Looping error

My gigantic while loop works great except that it repeats the very last line in the output. Any ideas on where the error might be would be appreciated.

Here is a piece of the loop:

Code:

while (!fin.eof()) {
    fin >> ch1;
      if ((ch1 == 'M') || (ch1 == 'F')) {
  fin >> ch2;
  if (ch1 == 'M') {
   males++;
  } else {
   females++;
  if (ch2 == 'A') {
   fin >> age;
   ageAccum = age + ageAccum;
   count++;
   fin >> dummych;
   fin >> weight;
   weightAccum = weight + weightAccum;
   count2++;
   newlog(ch1, age, weight, fout);
  } else {
   fin >> weight;
   weightAccum = weight + weightAccum;
   count2++;
   fin >> dummych;
   fin >> age;
               ageAccum = age + ageAccum;
   count++;
   newlog(ch1, age, weight, fout);
  }
  }

If you need the whole thing, let me know.

I've tried putting the first input before the while loop, but that didn't work. Any actual coding ideas?
