Question

c++

You have become fed up with waiting for Prof. Keeling to calculate your final grade. You have decided that to lower your frustrations and write a program to calculate your final grade and the grades of 5 of your classmates.

Use the structure chart below to guide the design of your program.

Create a file named "infile.txt" with data for you and your classmates. An easy way to create this file is to copy and paste the data below into a text file.

DO NOT INCLUDE THE HEADING IN YOUR INPUT FILE

For each student the main function calls each of the "compute" functions. These functions call the appropriate "get" function that uses the globally declared input file to read the individual scores from the file, adds them together and returns the total score for each assessment category (assignments, lab, quizes and exams). Use the following requirements to compute the grades (characters) that are to be returned to the main() function by each of the "compute" functions.

Use the weighted computations described below to compute the Final Grade (A - F) for each student.

Finally, in main print a report showing each student's Identifier (Student X) where X goes from 1 to 6. The report should show each component of the student's grade (lab, assignment, quiz and test letter grade) and each student's final letter grade.

Your can declare the input file as a global variable.

Your output should look like the screen below:

Use the following code to get started:

When you are finished, copy and paste your output to the end of your source code as a comment. Re-compile this commented code to make sure that your have not introduced any new errors.
