Assignment 4

Assignment 4 - Student Grades

Due October 21st

The purpose of this assignment is to give you practice using if, if ... else, and switch statements and more practice formatting output. This assignment should not be too difficult, so there will be emphasis on following the program requirements.

You are to write a program that calculates student grades following the rules for our class (not counting any extra credit).

400 points total
11 assignments, 20 points each, discard the lowest score.
midterms - 50 points possible
final - 100 points possible
Lab Exercises - 50 points possible
90-100% = A, 80-89% = B, 70-79% = C, 60-69% = D, less than 60% = F
A "+" will be added to the grade if it's 100%, 99%, 98%, 89%, 88%, 79%, 78%, 69%, or 68% (assuming points are rounded to the nearest percent).
A "-" will be added to the grade if it's 91%, 90%, 81%, 80%, 71%, 70%, 61%, or 60%.
A grade less than 60% will not receive a plus or minus.

Program requirements

Declare at least 19 variables.
Use type unsigned short for variables that are used to hold point values.
Use a named constant for the maximum points available, 400.
Match the output shown below.
Use a switch statement to determine the letter grade.
Use a manipulator to print the assignment grades using a width of 4.
The percent of total should be rounded to the nearest percent.
After printing the letter grade, and the plus or minus, if applicable, print one of the following messages.

if the grade is an A, print "Excellent work"
if the grade is a B or C, print "Not bad!"
if the grade is D or F, print "You better try again"

Your program will be run using one of the following test cases.
