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.

Your program must be able to work for an input file that contains following information:

# of temperature readings

time stamp

temperature

[# of temperature readings] [time stamp] [temperature]

The time stamp will have the following format:

YYYYMMDDHHMM (e.g. 200708201425)

This should be converted to: 08/20/2007 1425

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 1245

19.97 C --- recorded on 08/22/2007 at 0812

Average Temp --- 20.68 C

Note: You must format the floating point numbers to two decimal places.

Input to program: Input file of time stamps and temperatures (Name this file "biodata.dat"). For testing purposes you have to create this file yourself according to the rules described above. Grader will use his/her own file to test your program but your submission must still include the input file that you created.

Output from program: Formatted output must be stored in "filtered_biodata.dat". This file should be created by your code.

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.

You must use character arrays (c-strings) to re-arrange data. You cannot use string objects and any methods that are included in library, i.e, you cannot use #include in your code, otherwise you will be penalized. You can use c-string library -

Error processing. You program must detect several errors in the input file. Please refer to the grading criteria document for the details.
