Arrays and Design Assignment

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 data

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.

Average high: 47.4 F

Average low: 28.4 F

Highest temperature for the day: 72 F

Lowest temperature for the day: -2 F

Histogram of high temperatures:

vertical axis: range of temperatures

horizontal axis: number of temperatures in that range

(Hint for printing out labels: If you want to print out a set of string constants, you can store them in an array and then print them out from the array. Example

string grade_level [4] = {"Freshman", "Sophomore", "Junior", "Senior"};

for (int level = 0; level < 4; level++)

cout << grade_level[level] << endl;
