what input file are you speaking of?

I'm hoping you can help me with this C++ program. As I am in beginning C++, this seems very overwhelming based on the amount of pages to take in. There isn't any rush, if you can go through it thoroughly. Please show code based on specifications. Thank you in advance for your help.

CS 210 Lab 7 Specifications Checkpoint due 11:59PM Fri Mar 1 Lab Due 11:59PM Tue Mar 5 Lab 7 Overview: In Lab 4 you wrote a program to produce a report based on the data in the classData.dat file that contains student's names and test scores. In this lab, you will again process the data in the classData.dat file (or shortClassData.dat), but you will do so in a very different way Each student's information will be stored in a StudentRecord object which contains the student's name and an array of their test scores Your program will manage an array of StudentRecord objects You will implement some elementary exception-handling code . . . . This will eventually be a multi-file project containing files named StudentRecord.h StudentRecord.cpp, and StudentGradeReport.cpp. You will write this program in stages. You are strongly discouraged from p before completing the earlier stages. to another stage Lab 7 Stage 1 (Checkpoint): If you have not already done so, download and unzip the compressed Lab7Files folder. It contains a file named Lab7Driver.cpp that is a template for your Stage-1 Checkpoint code. That code should fill and display an array of StudentRecord objects populated with the student data in the shortClassData.dat file. This shorter version of the classData.dat file contains only 5 students with 2 test scores each. When you have completed Stage 1, your program should be capable of generating the following I/O session Number of students in CS 210: 5 ACOSTA BRANDON M 1 APOLISTA TRIXIA 2 BOBBY ANTHONY J 91.868.80.0 50.1 65.0 0.0 72.778.50.0 98.351.70.0 70.190.80.0 BOESEL MITCHALL R BONSEN CHLOEE This report displays the course title, the number of students in the class, and the names, two test scores and average test score for each student. As you can see, the average score is just 0 at this stage Take a moment to study the Lab7Driver.cpp file located in the Lab7Files folder.
