As part of the mission of the CS student you have been commissioned to help clean up some of the data recently collected at Aquarena Springs. It turns out the biologists who were collecting water temperatures forgot to agree on which temperature scale to use. Some used Fahrenheit and some used Celsius. The biologists used a thermometer that recorded the time and date of the reading and the temperature. Your job is to create a human readable output file that shows the time and date, as well as the temperature in Celsius. Lastly, you need to print out the average temperature for the entire sample, in Celsius.
Note: You should not use an array for this assignment.
Hint: The function "atof(char *)" will take a C-style string and convert it to a floating point number. Look at the string functions to see how you can use these to get the code for the kind of reading and the temperature. We will work with these in class, too.
You will be given an input file with the following format:
# of temperature readings
a time stamp followed by a temperature
The time stamp will have the following format:
YYYYMMDDHHMM (e.g. 200708201425)
This should be converted to:
08/20/2007 14:25
The temperature will have the following format:
Xtemp, where X is either a C or an F (e.g. C17.5 or F68.34)
Note that some of the temperatures are already in Celsius and some are in Fahrenheit. You only need to convert the Fahrenheit temperatures to Celsius.
So, the file could look like this
2
200707211245 F70.5
200708220812 C19.97
and the output could look like this:
BIODATA Formatted Ouput
21.38 C --- recorded on 07/21/2007 at 12:45
19.97 C --- recorded on
08/22/2007 at 08:12
Average Temp --- 20.68 C
(Note: Please format the floating point numbers to two decimal places.)
Input to program: Input file of time stamps and temperatures (Name this file "biodata.dat")
Output from program : Formatted output to a file named "results.dat" (updated 1/21/09)
You should have at least two functions: One to
convert the time stamp to a human readable string and another to
convert a Fahrenheit temperature to Celsius. You may have more if you
wish.
IMPORTANT!
On top of each file include your name, date and assignment number.
