Programming to coutn the examids

     cout << "File is successfully opened" << endl;
     vector <student> students;
     student aStudent;
     string tempStudentID;
     bool readEntireFile = false;     // set to true when reach end of file
     stream1 >> tempStudentID;    //  read in student id of first student
     while (!readEntireFile)
     aStudent.studentid = tempStudentID;  // new student
     int tempExamCode;
     aStudent.examcode.clear ();
     stream1 >> tempExamCode;    // read in first exam code for this student
     aStudent.examcode.push_back (tempExamCode);  // add this exam code to current student's vector of exam codes

     while (!newStudent && !readEntireFile)  
     if (stream1 >> tempStudentID)   // successfully read in student id
     if (tempStudentID.compare (aStudent.studentid) == 0)  // student id is same as before
     stream1 >> tempExamCode;   // read in exam code

}   // if new student, do not repeat this while loop

     students.push_back (aStudent);   // no more exam codes for this student.  Add aStudent to students vector
     stream1.close ();  // We have read the entire file, so time to close it.
     for (int i = 0; i < students.size (); i++)
