For this assignment you will write a program that reads in climate data (imagine it is coming from a weather station) and stores that data in a linked list. After reading and storing all of the data your program will generate a report from the data.

The objective of this assignment is to learn how to implement a linked list and to gain familiarity with using a linked list in solving a problem. Since one of the objectives is to learn how to implement a linked list you cannot use the STL linked list.

Your program should use good design methodologies so you should have separate classes for each of the following:

- datalogger -- This class represents the "business logic" of adding data to the storage. This class also handles filtering out duplicate data items (see the requirements listed below). This is the only class that weatherlog.cpp knows about and it expects two methods: addData() and printReport(). - linkedlist -- This class should implement a linked list. This class should be distinct from the datalogger class (although I would expect datalogger to have a data member that is a linkedlist object). - weatherdata -- This class encapsulates the weather data (time, temperature, windspeed).

You are welcome to create any additional classes that you need.

Below are the specific external and internal requirements for this assignment. Your program will be evaluated based on these requirements.

== External Requirements ==

- The main driver (weatherlog.cpp) will provide a sequence of data readings. The program needs to store these readings. After all of the data is read in, the program must create a report identical to the one in the expected.txt output file. - Data with a duplicate timestamp indicates contradictory or inaccurate data and should not be stored (all records with the same timestamp). - The report includes: - a line that states the timestamp range - a line that states the number of data entries - a temperature section that contains a detailed report (see below) - a windspeed section that contains a detailed report (see below) - detailed report data: - the minumum value measured - the maximum value measured - a list of all of the readings >= the 99% reading (in order) - a list of all of the readings <= the 1% reading (in order) - see the provided "expected.txt" to see the report format

== Internal Requirements ==

- The program must use the supplied weatherlog.cpp file, unmodified, as the main driver. - All of the weather data must be stored in a linked list. - The linked list must have three separate "chains". One that keeps the data ordered by timestamp, one that keeps the data ordered by temperature, and one that keeps the data ordered by windspeed. - Strings must be stored using char* variables, not std::string. - No memory leaks.

Weatherlog.cpp file:

#include #include #include "datalogger.h"

using namespace std;

int main(int argc, char** argv) {

datalogger dl;

if (argc != 2) { cout << "Usage: " << argv[0] << " " << endl; exit(0); }

// Read the data

char* datafile = argv[1]; ifstream infile(datafile); int timestamp; double temperature; double windspeed;

while (!infile.eof()) { infile >> timestamp; infile >> temperature; infile >> windspeed;

if (!infile.eof()) { dl.addData(timestamp, temperature, windspeed); } }

// Output the report dl.printReport();

return(0); }

This question has been asked before, http://www.chegg.com/homework-help/questions-and-answers/programming-assignment-assignment-write-program-reads-climate-data-imagine-coming-weather--q22881915. But was done incorrectly. There needs to be atleast 7 total files, weatherlog.cpp, datalogger.cpp, datalogger.h, linkedlist.cpp, linkedlist.h, weatherdata.cpp and weatherdata.h. Please take as long as you need to fully complete everything, as the previous post did not.
