CS99 Fall 2002
Lab #5 (9/31/02)
Due 10/4 at noon.

1. Objectives

Completing all tasks in this assignment will help you:
  - write nested selection statements
  - use $mod$
  - concatenate strings

First skim, and then, carefully read the *entire* exercise 
before starting any tasks!

2. Temperatures

Write a script M-File $temperature.m$ that will rate a user-input 
temperature. To determine the rating, your program will:
  - obtain a user input temperature. Assume that the user enters
    a real number in degrees Fahrenheit. If the user enters an
    illegal numerical value, the program finishes with a warning.
    Note that no temperature may be lower than -459.67 F.
  - determine an initial rating based on initial temperature ranges
    - A temperature of at least 90 F is "hot".
    - A temperature of at least 80 F and below 89F is "warm".
    - A temperature of at least 70 F and below 79F is "OK".
    - A temperature of at least 60 F and below 69F is "cool".
    - A temperature below 59 F is "cold".
  - modify the rating based on the specific temperature range:
    - If the temperature is warm or hot, then the first three values
      in the range are modified as "almost", whereas the last three
      values are modified as "very".
    - If the temperature is cool or cold, the modifications are
      reversed.
    - If the temperature is OK, no modifications are needed.
  - report the rating

Preferrably, you should use nested selection statements, the $mod$
or $rem$ function, and concatenate strings to produce the 
appropriate ratings.

Example sessions:
Enter temperature: 52
Your temperature is very cold.
Enter temperature: 67
Your temperature is almost cool.
Enter temperature: 99
Your temperature is very hot.

E-mail the script .M file to me by Friday at noon.
