Loading file into arrays....Functions not working.....Is file opening a loading correctly?

After fixing the errors and executing this program, it appears that the searchFor and displayClass functions arent working properly.  I have checked them and as far as I cant tell they are written correctly.  I am wondering if the Student.dat file is opening and loading correctly, when I search for a name that is in the file I get the "Student name was not found" message.  How can I tell if the file is opening and loading corectly?
The student.dat file has 7 students and thier grades listed in it as follows
Lisa Burden#100#80#50
Lucy Carter#100#95#90
Brad Emmons#80#70#75
Tom Hoover#60#50#20

Oh, and if you don't use '#' as a delimiter, the code works with

You are not calling 'loadArray()' in 'main()' - make that read

void main()
{
    char selection = ' ';



    //declare arrays
    string name[7] = {""};
    int test1[7] = {0};
    int test2[7] = {0};
    int test3[7] = {0};

    loadArray ( name, test1, test2, test3);

    selection = getSelection();
    while (selection != '0')
    {
         switch (selection)
         {
         case '1': displayClass(name, test1, test2, test3);
              break;
         case '2': searchFor (name, test1, test2, test3);
              break;
         default: cout << "Invalid selection" << endl;
         }
         selection = getSelection();
   
     }
    cout << "Program has ended, thank you, and goodbye!" << endl;

Thanks for your help, I have made the necessary changes but I am still having the same problem.  When I execute the program and choose number 1 to show the class list it flashes on the screen for a split second but it only has the first student on the list the rest are 0's.  And when I search for a name I am getting the error msg "student name not found" and it is running in a continuos loop.  I'm not sure what the problem is but I'll keep at it!  Thank you for your help!

Have you tried the above input file format? '#' isn't really a good delimiter...
