Project 2 - Basic Algorithms

CMSC 104, Fall 2001

Due Date:

Start of class, Thursday October 4, 2001.

Note that late projects will NOT be accepted.

Point Value:

This project is graded with a 100 point max score.

Objectives:

To practice solving problems in a generic manner.
To practice writing basic pseudocode for the solution of a problem.

Assignment:

Determine the generic solutions to the problems. Write the generic solutions in pseudocode. The pseudocode should be represented as discussed in class. Turn this work in on paper, not by e-mail. Type in the solutions using any word processor of your choice. No handwritten submissions will be allowed.

Make sure that your pseudocoded solutions include, as discussed in class:

the source of any input data
the destination of any output
labels for any output

You can use your own psuedocode standard. However if you use functions other than that discussed in class make sure you define them.
i.e. If you use Print instead of Display make sure to define it in words.

Problem 1:

Write an interactive program that will draw a hollow (the in-class problem was different) rectangle of asterisks (*). The program must also display the
dimensions of the rectangle. Error checking must be done to be sure that the dimensions are greater than zero. Ask the user again if the dimensions are zero.

Example :-
for length = 3 and width = 7

*******
* *
*******

Problem 2:

The grade in some course is based on the following:

4 Projects = 40%
3 Exams (20% each) = 60%

Total = 100%

If a student has the following project and exam grades at the end of the semester, calculate the final grade for the course:

     Project 1 = 20/20
     Project 2 = 90/100
     Project 3 = 70/75
     Project 4 = 19/25
     Exam 1 = 92/100
     Exam 2 = 80/100
     Exam 3 = 81/100

Give the specific solution to this problem.

Then give an interactive generic algorithm where you get the grade of each project and exam. The maximum grade per project or exam will
be the same as in the above list i.e. maximum points for project1 are 20, for project2 are 100, exam1 are 100 and so on. Perform error checking
to see that the grade entered is not greater than the maximum grade and not less than zero. Display all the grades as shown above and the final
grade for the class.

You should do this project independently. The work you submit should be your own. Instances of cheating will not be tolerated. You will
fail the class if found copying or discussing solutions with other students.
