    while loop not reading eof

    I'm working on this program and need help! For some reason the while loop is not recognizing the end of file int he text file.

    Here's my code:

    Code:
    transIn.open("trans1.txt");
          while (!transIn.eof())
         {
               withdrawalAmt = 0.0;
               depositAmt = 0.0;
               transAmt = 0.0;
               numTrans = 0;
                          transIn >> acctChar >> acctNum >> begBal;
                          ch = transIn.peek();
                          if (ch != '\n') {
                          do
               {
                                                                       transIn >> transChar;
                       if (transChar == 'W')
                       {
                         transIn >> transAmt;
                         withdrawalAmt = withdrawalAmt + transAmt;
                         numTrans++;
                       }
                       else if (transChar == 'D')
                       {
                         transIn >> transAmt;
                         depositAmt = depositAmt + transAmt;
                         numTrans++;
                       }
                                    ch = transIn.peek();
                               } while (ch != '\n');
               }
               cout << fixed << showpoint << setprecision(2);
               cout << acctChar << acctNum << " " << begBal << endl;
               cout << withdrawalAmt << " " << depositAmt << " " << numTrans << endl;
         }
    Any help would be appreciated!

    You're probably never triggering it. Replace:

    Code:
    while (!transIn.eof())
    With

    Code:
    while (transIn.peek() != EOF)

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
