Overview

In this assignment you will create user-defined functions OUTSIDE the main program and call those functions from INSIDE the main program.

Instructions

This assignment will require you to create functions in the program which the main procedure calls.

Write a C++ program that

Reads data from an input file. The data file should include 10 students. Each student should have
Takes the data and computes student grades for an assignment by converting the raw score to a percentage given each student's score and the total points.

Round the final score up to the nearest whole value using the ceil function in the <cmath> header file and displayed as a percentage. You must also display the floating-point result up to 5 decimal places.

You must use at least 2 functions: one to print the last name of the student and another function to compute and print the percentage as well as "Excellent" if the grade is greater than 90, "Well Done" if the grade is greater than 80, "Good" if the grade is greater than 70, "Need Improvement" if the grade is greater than or equal to 60, and "Fail" if the grade is less than 50. The main function is responsible for reading the input file and passing the appropriate arguments to your functions.

Write a C++ program that
1. Reads data from an input file. The data file should include 10 students. Each student should
have
2. Takes the data and computes student grades for an assignment by converting the raw score to
a percentage given each student's score and the total points.
3. Round the final score up to the nearest whole value using the ceil function in the <cmath>
header file and displayed as a percentage. You must also display the floating-point result up to 5
decimal places.
4. You must use at least 2 functions: one to print the last name of the student and another
function to compute and print the percentage as well as "Excellent" if the grade is greater than
90, "Well Done" if the grade is greater than 80, "Good" if the grade is greater than 70, "Need
Improvement" if the grade is greater than or equal to 60, and "Fail" if the grade is less than 50.
The main function is responsible for reading the input file and passing the appropriate arguments
to your functions.
Here is an example of what the input file might look like:
name score tot possible
Weems 50 60
Dale 51 60
Richards 57 60
Smith 36 60
Tomlin 44 60
Bird 45 60
Here is an example of what the output of your program might look like:
Heems 83% .83333 Well Done
Dale 85% .85000 Hell Done
Richards 95% .95000 Excellent
Smith 60% .60000 Need Improvement
Tomlin 73% .73333 Good
Bird 75% .75000 Good
