HELP WITH PROJECT c++ (Array, string file, sort)

[trazafin]

Okay, I have this project due today. I have written the codes.
I need to read a .txt file and put it in an array.
Next, i need to sort the array alphabetically.
I was capable of reading the string file, however it does not display properly.
It suppose to display: first, lastname
however, mine displays: first,
lastname
Here is my code. It would be much appreciated if anyone could help me.
1. Displaying the name properly.
2. sort all of the names alphabetically
3. send the sorted name into different .txt file

This is the file (names.txt):
Collins, Bill
Smith, Bart
Allen, Jim,
Griffin, Jim
Stamey, Marty
Rose, Geri,
Taylor, Terri
Johnson, Jill,
Allison, Jeff
Looney, Joe
Wolfe, Bill,
James, Jean
Weaver, Jim
Pore, Bob,
Rutherford, Greg
Javens, Renee,
Harrison, Rose
Setzer, Cathy,
Pike, Gordon
Holland, Beth
