My output is has everything I need for the assignment, but I have racked my brain trying to figure out how to get the "printHeading()" function to have equal distances between the names---> ID---> hours, etc.

Is it that I have to find the length of the strings, and go from that? It confuses me a little and was wondering if someone could point me in the right direction.

And a preemptive thank you to any help.


I would post a picture of the output, but I don't know how =(.

Whats wrong with using the space bar.
ie;

 cout << "Student Name" 
             << setw(20) << "Student ID" 
             << setw(7) << "Hours  " 
             << setw(7) << "Hours          " //<--press space bar until lined up or adequate space etc
             << setw(6) << "Pts  " 
             << setw(6) << "GPA" 
             << setw(11) << "Status\n\n";

Are you just trying to put an equal # of spaces between words?
If so, forget setw() and print spaces.

cout << "Student Name" 
             << "     " << "Student ID" // 5 blank spaces between each word
             << "     " << "Hours" 
             << "     " << "Hours" 
             << "     " << "Pts" 
             << "     " << "GPA" 
             << "     " << "Status\n\n";

Haha, is my face red.

This is how fried my brain is, I have the printHeading() set up right, but its the lines (83-91) where it repetitively prints the data from the file.

 cout << lastName << " "
                  << setw(1) << firstName 
                  << setw(18) << iD
                  << setw(5) << attHours 
                  << setw(7) << studentHoursPassed
                  << setw(7) << qualPts;
          cout << fixed << showpoint << setprecision(3);
          cout << setw(7) << GPA
                  << setw(20) << status << "\n";

It prints out all jagged.

Cleese, John   111-11-111  12  11  21  1.750  probation
Idle, Eric   222-22-222  14  11  32  2.286
Palin, Michael  333-33-333 6  6  21  3.5000
Jones, Terry   444-44-444  12  15  44  2.933

And so on.

Any thoughts??
