Lab 6 Dynamic Arrays/Files Solution

Description

PROGRAM SPECIFICATIONS

Meteorologists love to keep statistics on the weather. They often tell us the maximum temperature for some date, or the minimum value for some date, or even how long it has been since Spokane experienced a 60 degree day. Your task is to use dynamic arrays provide some of the same statistics that a meteorologist does.

Your task:

• Your data will come from a file named temps.txt – My code prompts the user for the filename.

• The first line in the file will contain the number of days

• The file will then contain that number of entries for the number of days, one per line.

• Create an array of the exact size needed

• Fill the array with the values from the file.

• Repeatedly display the menu that has the following choices

• 1. Find and display the max temperature

• 2. Find and display the min temperature

• 3. Find and display the mean (average) temperature for the month

• 4. Find and display the median temperature for the month

• 5. Find and display the mode temperature for the month – if all the same then the lowest temp

  6. Allow the user to load a new file

• 7. Quit

You must range check menu entries

I have provided cscd240Lab6.c – As always you can’t change my main

TO TURN IN

A zip file that contains Lab6 folder and: – You better know the naming scheme by now

• All your code required to compile and execute your program

• A valgrind run to show you don’t leak memory named cscd240lab6val.txt

• An output run of your program named cscd240lab6out.txt

15. At least 2 runs over your program and make sure you test everything
