Description

This homework is a "starter" assignment and contains lots of independent questions to test your knowledge. The questions draw upon your readings, some of which are for next Monday's class.

  1. [20 pts.] Write a program that computes (a) the volume of a cylinder with radius 6 and height 3; (b) the volume of a sphere given radius 5; (c) the volume of a pyramid whose height is 4 and whose base is a square with dimensions 2 by 3. Once all values are calculated, you should output the statement "The XXXX has the largest volume of YYYY" where XXXX is the shape that had the largest volume, and YYYY is the actual volume as calculated in steps (a), (b), or (c).
     
  2. [20 pts.] Write a program that determines whether a String value starts and ends with the same letter. (Ignore capitalization, thus 'A' should be the same letter as 'a'). Your program must follow the design recipe introduced in class on Friday Oct-27 and described on the course web page for design recipes. Your program should output on a single line the statement "The word starts and ends with the same letter" if the String value does, and "The word does not start and end with the same letter" if the String value doesn't.
     
  3. [20 pts.] Write a program that uses a while loop that prints a table of temperature conversions from Celsius to Fahrenheit. Note that the order of the output is in reverse order from 40 degree Celsius down to -10 degrees Celsius.

    The table output should look like the following:

     
    Celsius : Fahrenheit
--------------------
40 : 104.0
39 : 102.2
38 : 100.4
37 : 98.6
36 : 96.8
35 : 95.0
34 : 93.2

...

-5 : 23.0
-6 : 21.2
-7 : 19.4
-8 : 17.6
-9 : 15.8
-10 : 14.0

     

  4. [20 pts.] Write a program to read from the keyboard two lines of input. Each line is prompted by a statement "Enter Line #:". The input will contain a sequence of characters which was terminated by the user pressing "Enter/Return". Your program should print out the statement "Line 2 is a reverse of Line 1" if the sequence of characters for Line 2 are the reverse of Line 1; Otherwise, output "No Comparison". For example, a sample run of your program is shown below:

     
    Enter Line 1:
This is the Line
Enter Line 2:
eniL eht si sihT
Line 2 is a reverse of Line 1

     

  5. [20 pts.] Write a program that reads a set of integers, one per line, until the end of input has been reached (in Eclipse, this is done by typing "Control-Z" in the Console window. You can assume that at least two numbers will be typed in. Once all integers have been read, your program should output from this set of numbers: (a) the minimum number; (b) the maximum number; and (c) the total sum of all numbers entered. For example,

     
    10
20
33
-8
<Control-Z pressed here>
Minimum: -8
Maximum: 33
Sum: 55

Deliverables

Your goal is to turnin the Project files by Tuesday October 31st at 10:00 AM  Further details will be posted HERE showing the preferred means of uploading your solution to the TAs. Please be aware that no late homeworks will be accepted. This means that we will grade as zero any homework not submitted by the above turnin means.

Notes

  1. Any updates to the homework will be described here, with timestamps.
  2. [10/27 2:54 PM] Homework1 completed and ready to go.
  3. [10/29/2006 5:34 PM] Note that the String example for problem 4 must treat lower case 'a' and upper case 'A' as different letters. I fixed the example (note the capital T in red) to properly reflect this.
