Lab Project #6

Due: 9/28/2009

1. Write a program that prompts the user to enter the number of students and each student’s name and score, and displays the name and score of the student with the highest score and the name and score of the student with the second highest score. (See problem 4.9 on page 134 of the textbook.)

2. Rewrite Listing 4.9 on pages 119-120 of the textbook (FindSalesAmount.java) as follows:

· Use a for loop instead of a do-while loop.

· Let the user enter COMMISSION_SOUGHT instead of fixing it as a constant.

(See problem 4.17 on page 134 of the textbook.)

3. Write a program that displays all the leap years, ten per line, in the twenty-first century (from 2001 through 2100). (See problem 4.27 on page 137 of the textbook.)

4. Revise Listing 3.5 of the textbook (Lottery.java) to generate a lottery of a two-digit number where the two digits are distinct. (Hint: Generate the first digit and use a loop to continuously generate the second digit until it is different from the first digit.) (See problem 4.33 on page 139 of the textbook.)

For each of the above problems be sure to do the following:

1. Plan your solution by writing down the algorithm to solve the problem before you write the code.

2. Make sure your programs are self-documented including an appropriate comment header block.

3. Test the programs by running at least three test cases on each.

For each problem, turn in your algorithm design (this can be a skeleton program with comments only or a hand written description of the algorithm), a listing of the program, and a listing of the output from running the test cases.
