Lab 03

A Below Average Winter

Objective:

Write a program that takes in temperatures for 10 days and stores it in an array.  Find the average temperature for those 10 days, and then print the number of days and the temperatures that were strictly below the average.

Lab Solution

Requirements:

• Functionality. (80pts)
• No Syntax, Major Run-Time, or Major Logic Errors. (80pts*)
• *Code that cannot be compiled due to syntax errors is nonfunctional code and will receive no points for this entire section.
• *Code that cannot be executed or tested due to major run-time or logic errors is nonfunctional code and will receive no points for this entire section.
• Only use Arrays to store the collection. (80pts*)
• *Any other data structure such as LinkedLists, ArrayLists, etc. will result in no points awarded for this entire section.
• Clear and Easy-To-Use Interface. (20pts)
• Users should easily understand what the program does and how to use it.
• Users should be prompted for input and should be able to enter data easily.
• Users should be presented with output after major functions, operations, or calculations.
• All the above must apply for full credit.
• Inputting the Temperatures. (20pts)
• The user must be able to enter the 10 temperatures.
• These temperatures must be stored in an Array of a decimal type.
• All the above must apply for full credit.
• Finding the Average. (20pts)
• Once the temperatures have been entered, the average temperature must be calculated and displayed.
• The average is the sum of all of the values in the Array divided by the size (or length) of the Array.
• All the above must apply for full credit.
• Printing All Temperatures Below the Average. (20pts)
• Once the average has been calculated, the program must display all temperatures that are strictly below the average.
• If there are no temperatures strictly below the average, then the program should display nothing.
• Coding Style. (10pts)
• Readable Code
• Meaningful identifiers for data and methods.
• Proper indentation that clearly identifies statements within the body of a class, a method, a branching statement, a loop statement, etc.
• All the above must apply for full credit.
• Comments. (10pts)
• Your name in the file. (5pts)
• At least 5 meaningful comments in addition to your name. These must describe the function of the code it is near. (5pts)

Example Dialog:

Welcome to the below average temperature tester program.

Please enter the temperature for day 1

33.0

Please enter the temperature for day 2

20.0

Please enter the temperature for day 3

41.0

Please enter the temperature for day 4

48.0

Please enter the temperature for day 5

60.0

Please enter the temperature for day 6

51.0

Please enter the temperature for day 7

29.0

Please enter the temperature for day 8

71.0

Please enter the temperature for day 9

63.0

Please enter the temperature for day 10

66.0

The average temperature was 48.2

The days that were below average were

Day 1 with 33.0

Day 2 with 20.0

Day 3 with 41.0

Day 4 with 48.0

Day 7 with 29.0

Solution Tests:

1. Is your name written as a comment in all source files?
2. Does the solution compile (no syntax errors)?
3. Given the input <33.0, 20.0, 41.0, 48.0, 60.0, 51.0, 29.0 71.0, 63.0, 66.0> does the program print out:
   The average temperature was 48.2

The days that were below average were

Day 1 with 33.0

Day 2 with 20.0

Day 3 with 41.0

Day 4 with 48.0

Day 7 with 29.0

4. Given the input <10.0, 20.0, 30.0, 40.0, 50.0, 60.0, 70.0, 80.0, 90.0, 100.0> does the program print out:
   The average temperature was 55.0

The days that were below average were

Day 1 with 10.0

Day 2 with 20.0

Day 3 with 30.0

Day 4 with 40.0

Day 5 with 50.0

5. Given the input <10.0, 10.0, 10.0, 10.0, 10.0, 10.0, 10.0, 10.0, 10.0, 10.0> does the program print out:
   The average temperature was 10.0

The days that were below average were
