Thread: link list

I have to use a link list to pull 10 names from a txt file and then put them in alphabetical order by lastname and then output the list in another file. any help will be greatly appreciated I only have one more day to work on it. Here is what I have so far. I cant figure out how to create a loop to do this.

Code:

#include <stdio.h>
#include <iostream.h>
#include <fstream.h>

const int ItemLen = 10;

//Node definition
struct ListNode
{
  char name[ItemLen];
  char lastname[ItemLen];
  ListNode *link;
 };

 typedef ListNode* ListNodePtr;

 ListNodePtr Head;

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

  char filename[25];
  char filelastname[25];
  int end;
  ListNodePtr p,q,r;
  Head= new ListNode;

  ifstream inFile;

    inFile.open("a:GOLFNAME.txt",ios::in);

  //verify that open was successful
  if(!inFile.fail()) //if open did not fail
    {
     cout<<"file Opened"<<endl;
      //read name

      while(!inFile.eof())
    {
     inFile>> filename>> filelastname;
     cout << "The name is: " << filename <<" "<< filelastname << endl;


      strcpy(Head->name,filename);
      strcpy(Head->lastname,filelastname);
      Head->link= NULL;
    }
    inFile.close();
    //display name
    }
    else
      cout<< "Error opening file." << endl;
     // open failed//end if

      p=Head;
   while(p !=NULL)
   {
     cout<< p->name << " " << p->lastname << endl;
     p= p->link; //Get the next node
   }

       cin>> end;
  return 0;
}
