Question

C++

Write a program that reads student's names followed by their test scores from the input file i provided in Canvas. The program should output to a file, output.txt, each student’s name followed by the test scores and the relevant grade. It should also output the same data to the screen.

Student data should be stored in a struct variable of type StudentType, which has four components: studentFName and studentLName of type string, testScore of type int and grade of type char. suppose that the class has 20 students. Use an array of 20 components of type StudentType.

Your program must contain at least the following functions:

1. A function to read the student's data into an array.

2. A function to assign the relevant grade to each student.

Your program should output each student’s name in this form: last name followed by a comma, followed by a space, followed by the first name; the name must be left justified. Moreover, other than declaring the variables and opening the input and output files, the function main should only be a collection of function calls.

Your program should open C:\Project4\Ch9_Ex2Data.txt and write the output to that same folder (C:\Project4\output.txt). The slash syntax will depend on what compiler you are using.

C:\project4\Ch9_ex2Data.txt
