For this project I am suppose to create a data file which includes this info:

Miller Ford Mustang 28000
Miller Ford Escape 23000
Miller Ford Van 32000
Sam_Car Ford Focus 17000
Sam_Car Ford Ranger 18250
Sam_Car Chev Impala 31500
Tina_Sells Chev Camero 33000
Tina_Sells Chev SUV 38000

Then I am suppose to create a program that reads in all the data but uses a control break, one that subtotals each salespersons sales. then it it suppose to display the read data including the subtotal, and earned commission which is 4% of the total sales (subtotal).
This is what I have so far, it read all the data and displays it. I just need help on how to start on the subtotaling for each seller? Can anyone show me an example or lead me in the direction to a solution for my program? Thanks.

You should pay attention to how you have divided your problem into functions.

A function like computeCommission(int price) can be useful...
