Question

C++ really need help I will rate you well promise

Write a program that will use a linked list to hold the following information:

Date (int), Time (int), TZ (string), Size (Int) and Name (string)

Follow the guidelines below:

Records should be read from a file by the main program. And content should be stored in the doubly linked list or single linked list.

After that, you can print separately dates or times or names ... or print hole line  

Use the following information for testing purposes:

Date Time TZ Size Name

Answer 1

The date and time in the program are in a format so they are taken as string please comment if you have any doubts

#include<iostream>
#include<fstream>
#include<string>
#include<stdlib.h>
#include<vector>
#include <cstdlib>
#include <sstream>
using namespace std;
struct node
{
   string date;
   string time;
   string TZ;
   string name;
   int size;
   struct node *next;
};
void tokenize(string const &str, const char delim,
           vector<string> &out)
{
   size_t start;
   size_t end = 0;

   while ((start = str.find_first_not_of(delim, end)) != std::string::npos)
   {
       end = str.find(delim, start);
       out.push_back(str.substr(start, end - start));
   }
}

class linked_list
{
private:
node *head,*tail;
public:
linked_list()
{
head = NULL;
tail = NULL;
}

void add_node(string date, string time, string TZ, int size, string name)
{
node *tmp = new node;
   tmp->date = date;
   tmp->time = time;
   tmp->TZ = TZ;
   tmp->size = size;
   tmp->name = name;
tmp->next = NULL;

if(head == NULL)
{
head = tmp;
tail = tmp;
}
else
{
tail->next = tmp;
tail = tail->next;
}
}
void display()
{
   node *current = head;
   while(current != NULL)
   {
       cout<<current->date<<endl;
       cout<<current->time<<endl;
       cout<<current->TZ<<endl;
       cout<<current->size<<endl;
       cout<<current->name<<endl;
       current = current -> next;
   }
}
};

int main()
{
   ifstream file("data.txt");
   string str;
   getline(file, str);
   getline(file, str);
   while(str != "")
   {
        const char delim = ' ';
       vector<string> out;
       tokenize(str, delim, out);
       stringstream convert(out[3]);
       int size;
       convert >> size;
       linked_list a;
       a.add_node(out[0], out[1], out[2], size, out[4]);
       getline(file, str);
       a.display();
      
      
   }
}
