Maybe not the best way, but it works for me

Code:

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




class player
{
public:

player(){}//:
//health (10),
//speed (50){}

friend istream& operator >>(istream& stats,  player&p)
{
return stats>>p.health>>p.speed;
//this here is overloaded so you can enter both a health and a speed
//for the player for example when the computer asks you for an input
//cin>>first.........then you input 10 (Enter) 50
}



void SetHealth(int health){health=health;}
int const GetHealth() {return health;}

int health;
int speed;

};

int main()
{

player first;//looks like I would have to create a class
//if I wanted to load the stats for a certain player I 
//would have to create a player class.........

cout<<"Enter the Player's Health and speed separated by pressing Enter"<<endl;
cin>>first;

ofstream saveplayer ("playerstats.txt", ios::app);

saveplayer<<first.health<<"\n"<<endl;
saveplayer<<first.speed<<"\n"<<endl;
saveplayer.close();


ifstream read ("playerstats.txt");
cout<<"Now I shall display the stats"<<endl;

read>>first.health;//boots up the stats.......kind of
read>>first.speed;
cout<<first.health<<endl;//displays it on the screen
cout<<first.speed;

read.close();

int x;//this is when I used DevC++
cin>>x;

//this is also some old stuff I kind of reworked some time ago.
      return 0;
}

Try this.

Code:

#include <iostream>
#include <fstream>

using namespace std;

int main(void)
{
   int scores[10] = {30000,29000,25000,20000,10000,5000,4000,3000,200,100};
   int i, score;
   char filename[80] = "scores.txt";

   //Write high score file
   ofstream out(filename);
   if (!out)
   {
      cout << "Unable to open file:" << filename << endl;
      return 1;
   }

   for (i=0; i<10; i++)
      out << scores[i] << " ";
   out << endl;
   out.close();

   //Read high score file
   ifstream in(filename);
   if (!out)
   {
      cout << "Unable to open file:" << filename << endl;
      return 1;
   }
   cout << "*****     Top Ten High Scores     *****" << endl;
   for (i=0; i<10; i++)
   {
      in >> score;
      cout.width(5);
      cout << i+1 << ": ";
      cout.width(10);
      cout << score << endl;
   }
   in.close();

   return 0;
}
