Ok so this is what I am trying to do but seem to have a problem with my input loop because it keeps reading in only the first set of student data. I am also unsure where to put the cin.ignore because my getline function is not working. Please fogive me for all the code commented out I've just been having a tough time with this program. Any help you could give me I would greatly appreciate.
-thank you

Program Design: Your main function in the client program pgm6main.cpp should do the following:
1. Declare an array of Student objects that can hold up to 10 student's data.
2. Read in the data from the file pgm6.dat. Store the last name, first name, major, cumulative quality points, and cumulative credits in the next available element of the array. For each class the student has completed for the semester read in the letter grade and course credits. Pass these to the updateCumData member function to update the cumulative points and credits.
3. Call a function to display a menu and return a menu selection. For menu selections 1-4 call a function as described below to carry out the operation. The menu should look like this:

1. Print student list
2. Add new student
3. Change student major
4. Delete student
5. Quit

Enter selection (1-5):

#include "pgm6.h"
#include <iostream>
#include <fstream>
#include <iomanip>

using namespace std;
void displayMenu(Student[], int);
void printStudentList(Student[], int);
void addStudent();
void changeMajor();
void deleteStudent();

int main(){

int pstudentID, pcumPoints, pcumCredits, pCredits;
string plastName, pfirstName, pmajor, gradeLvl, pGrade;
ifstream indata;
int i = 0;
int filledCount;
//double GPA;

Student classMate[10];


indata.open("lib/pgm6.dat");

  indata >> pstudentID; //prime the loop

while (!indata.eof() && i < 10){

   classMate[i].setstudentID(pstudentID);
  indata >> plastName;
   classMate[i].setlastName(plastName);
  indata >> pfirstName;
   classMate[i].setfirstName(pfirstName);
  getline (indata, pmajor);
   classMate[i].setMajor(pmajor);
  indata >> pcumPoints;
   classMate[i].setcumPoints(pcumPoints);
  indata >> pcumCredits;
   classMate[i].setcumCredits(pcumCredits);
  indata >> pGrade;
  indata >> pCredits;
   classMate[i].updateCumData(pGrade, pCredits);
  i++;
  filledCount++;
  indata >> pstudentID;

} //end while

displayMenu(classMate, filledCount);




return 0;}

//************************************************

void displayMenu(Student classMate[], int filledCount){
 int choice;
 cout << "1. Print student list" << endl;
 cout << "2. Add new student" << endl;

 cout << "4. Delete student" << endl;
 cout << "5. Quit" << endl;
 cout << endl;

 cout << "Enter selection (1-5): " << endl;
 cin >> choice;
 if (choice == 1)
    printStudentList (classMate, filledCount);
// else if (choice == 2)
//    addStudent ();
// else if (choice == 3)
//    changeMajor ();
// else if (choice == 4)
//    deleteStudent ();
// else;
}

//************************************************

//************************************************

void printStudentList(Student classMate[], int filledCount){
 cout << setw(15) << "StudentID";
 cout << setw(15) << "Last Name";
 cout << setw(15) << "First Name";
 cout << setw(15) << "Major";
 cout << setw(20) << "Quality Points";
 cout << setw(15) << "Credits";
 cout << setw(15) << "GPA";
 cout << setw(15) << "Status" <<endl;
 cout << "---------------------------------------------" <<endl;

int i;

 for(i=0; i<filledCount; i++){
  cout << setw(15) << classMate[i].getstudentID();
  cout << setw(15) << classMate[i].getlastName();
  cout << setw(15) << classMate[i].getfirstName();
  cout << setw(15) << classMate[i].getMajor();
  cout << setw(15) << classMate[i].getcumPoints();
  cout << setw(23) << classMate[i].getcumCredits();
//  cout << setw(20) << classMate[i].getGPA();
//  cout << setw(15) << classMate[i].getStatus();
  cout << "" << endl;
  }//end loop

}// end function

and this is the output that i get when running it

1. Print student list
2. Add new student
3. Change student major
4. Delete student
5. Quit

Enter selection (1-5):

You need to initialize filledCount to zero (or get rid of it and just use i).

Try putting the cin.ignore() before cin >> choice

I did what you said but and now I get through the input loop and to the display but I get no output at all now when I print the list. I also noticed that I need to create a loop to take in the number of classes and input the grade and credits for each. I've added that loop but their seems to be a problem with the number of classes input becuase I output it and it always comes out 0.

indata.open("lib/pgm6.dat");

  indata >> pstudentID; //prime the loop

while (!indata.eof() && i < 10){

   classMate[i].setstudentID(pstudentID);
  indata >> plastName;
   classMate[i].setlastName(plastName);
  indata >> pfirstName;
   classMate[i].setfirstName(pfirstName);
  getline(indata, pmajor);
   classMate[i].setMajor(pmajor);
  indata >> pcumPoints;
   classMate[i].setcumPoints(pcumPoints);
  indata >> pcumCredits;
   classMate[i].setcumCredits(pcumCredits);
  indata >> numClass;
  cout << "classes: " << numClass << endl;
  while (classCount < numClass)
  {
     indata >> pGrade;
     indata >> pCredits;
        classMate[i].updateCumData(pGrade, pCredits);
     classCount++;
  }
  i++;
  filledCount++;
  indata >> pstudentID;

} //end while

displayMenu(classMate, filledCount);

here's what i get when I run the program

classes: 0
classes: 0
classes: 0
classes: 0
classes: 0
classes: 0
classes: 0
classes: 0
classes: 0
classes: 0
1. Print student list
2. Add new student
3. Change student major
4. Delete student
5. Quit

Enter selection (1-5):
1
