Chapter 2, Problem 6P

The following algorithm is designed to determine a grade for a course that consists of quizzes, homework, and a final exam:

Step 1: Input course number and name.

Step 2: Input weighting factors for quizzes $\left(\text{WQ}\right)$, homework $\left(\text{WH}\right)$, and the final exam $\left(\text{WF}\right)$.

Step 3: Input quiz grades and determine an average quiz grade $\left(\text{AQ}\right)$.

Step 4: Input homework grades and determine an average homework grade $\left(\text{AH}\right)$.

Step 5: If this course has a final grade, continue to step 6. If not, go to step 9.

Step 6: Input final exam grade $\left(\text{FE}\right)$.

Step 7: Determine average grade AG according to

$\text{AG}=\frac{\text{WQ}\times \text{AQ}+\text{WH}\times \text{AH}+\text{WF}\times \text{FE}}{\text{WQ}+\text{WH}+\text{WF}}\times 100\%$

Step 8: Go to step 10.

Step 9: Determine average grade AG according to

$\text{AG}=\frac{\text{WQ}\times \text{AQ}+\text{WH}\times \text{AH}}{\text{WQ}+\text{WH}}\times 100\%$

Step 10: Print out course number, name, and average grade.

Step 11: Terminate computation.

(a) Write well-structured pseudocode to implement this algorithm.

(b) Write, debug, and document a structured computer program based on this algorithm. Testitusingthefollowingdatato calculate a grade without the final exam and a grade with the final exam: $\text{WQ}=\text{30; WH}=\text{40; WF}=\text{30}$; quizzes $=\text{98, 95, 90, 60, 99}$; homework $=98,95,86,100,100,77$; and final exam $=91$.
