Arrays and Design Assignment

In this assignment Please first write a pseudocode using a text editor. Have it checked out by the instructor. You can start implementing as you are waiting, but you should have the pseudocode checked out before you get too far in writing code.

For this program, you will read in and analyze temperatures around the nation on a particular day. The input data will be in a text file called temperature.txt. The first line of the file will be a date; this can be read in as a string. This will be followed by an integer that gives the number of locations at which the temperatures were taken; this will be at least 2 and no more than 100. This is followed by that many lines (2 to 100), where each line has two integers representing the daily high and the daily low at one location. A short sample content of temperature .txt is given below.

The program should first read in the data from the file. Use two arrays, one to hold the high temperatures and the other to hold the low temperatures. Once the data has been read in, do the following analysis:

1. Find the average high and the average low for the day. Calculate the averages as real numbers, not integers.

2. Find the highest and the lowest temperature in the nation for the day.

Print the information in a readable format to a file report.txt, starting with a title with the date.

For the high temperatures only, calculate and draw a histogram. This means counting the number of temperatures that were less than 0, how many in the range 0 to 9, how many in the range 10 to 19, . . . , how many in the range 90 to 99, and how many were 100 or above. The counts must be in an array of size 12, one entry for the 12 ranges given. The counts should be plotted in a simple graph with a row of *s giving the count in each range. The task for getting the correct values for the count array should be implemented as a function. What will its parameters be? You may assume that the number of counts in any range will be less than the standard width for the output. See the example below for the given sample input

Once your program is working correctly, use the temperature.txt file posted on Titanium as input and turn in the resulting report.txt.

Extra challenge: In your function for getting the values for count , try doing it *without* using a big if.. else if else.. or a case statement to find which count [i] needs to be increased for a particular temperature.

1. Pseudocode

2. Your program including the following internal documentation:

a) Your name,

b) description of the purpose of the program

3. The output file report.txt.
