Using arrays and struct variables

dummy1001 (8)
Hello!
I am writing a program that should output to a file each student’s name followed by their test score and the relevant grade.

The problem i am having is outputting my data.
My program should output each student’s last name followed by a comma, followed by a space, followed by the first name. Next the fisrt name, output the score and grade on the same line. I need to use the left modifier, along with setw().
Here is what my input file is

Queen Louis 80
Jennifer Whatever 75
John Mark 65
