Question

Hi, Im new to C++ coding and need some help on a project. I have example code i'll provide, and if you could code this so I can see how its done that would be awesome. I'm using some data from twitter stored in a .cvs file that I will include in a link. The program has to be able to extract data from the .cvs file and display the amount of tweets that were tweeted during the first 12 hours, 24 hours, 1 week, and 2 weeks after the start of the data(it was data collected from a fire). I've been told the easiest way to read the .csv files is to use getline() for each line in the file and then use stringstream to parse the line. If you could use these methods that would be great.

main.cpp:

#include // Standard In/Out to terminal (cin/cout)
#include // File stream (ifstream/ofstream)
#include "TwitterUser.h"
#include "TwitterUsers.h"

/* Version 6: Code separated into separate class and header files

using namespace std;

int main()
{
// Step 1: Read in the data
string data;
TwitterUsers userRecords;
// declare and open the input file.
ifstream infile;
infile.open("twitterers.csv");
if (infile.good())
{
cout << "Reading in data..." << endl;
// Read in the headings and ignore.
getline(infile, data);
bool good;
// Get lines from infile until the end-of-file character is reached (EOF)
while (getline(infile,data))
{
good = userRecords.addTwitterUser(TwitterUser(data));
if (!good)
break;
}
}

// Step 2: Welcome message
cout << "Welcome. This program prints out the most active Twitterers from the " << endl;
cout << "2014 Carlton Complex Wildfire. You can select top tweeters overall or " << endl;
cout << "by user classification (e.g. Media or Official Organizations)." << endl;

{
// Display the menu
cout << endl;
cout << "PROGRAM MENU" << endl;
cout << "--------------------------" << endl;
