Week 4 iLab—Decision Calendar
TCO 4—Given a simple problem that requires one or more decisions, create a solution algorithm that uses decisions with logical and relational expressions.
TCO 8—Given a more complex problem, develop a complete solution that includes a comprehensive statement of the problem, complete program design, and program documentation.
Scenario
You have been asked to design a program that will allow a teacher to calculate the percentage and the final grade for students in a class. The program will prompt the teacher to enter the student’s first and last name and the number of points the student received. The program will only accept scores between 0 and 1,000 points (including 0 and 1,000), with 1,000 points being the maximum number of points. If the input value within the valid range, the program will display a “good score” message; otherwise, the program will display an error message and then terminate the program. The program will then calculate the score percentage and then determine the grade based on the percentage using the following grade criteria.
|
Score Percent Range |
Grade |
|
90—100 |
A |
|
80—89 |
B |
|
70—79 |
C |
|
60—69 |
D |
|
0—59 |
F |
The program will then display the student’s first name, last name, number of points, calculated percentage, and final grade.
The program will have an initial prompt informing the user of the program’s purpose, along with a program termination message.
Be sure to think about the logic and design first (IPO chart and pseudocode), then code the Visual Logic command line processing.
