Need help! C++, data from txt file into an array.

[Snipez]

When I try an put the input data into an array it crashes my program. I can put it into a single string but not an array of strings... This is needed so I can bring all the data in to compare it and rearrange it.
Data format in file;
NAME5006
NAME3050
NAME3213

These are highScores for a game I am currently making. I want to rearrange them so they can be output in order on the highscore page.

Any help appreciated.

#include <string>
#include <iostream>
#include <fstream>
#include <math.h>
#include <sstream>
string scoresort[9];

int HighScore(int PlayerScore){
int x;   
					
  				  fstream scorefile ("scores.txt");

				  string line;
				  
				  if (scorefile.is_open())
				  {
				    while (scorefile.good() )
				    {
					getline (scorefile,line);
        			scoresort[x] = line.c_str();
				    cout << line << endl;
				      
					  x++;
				    }
				    
				  }
				
				  else {cout << "File NOT opening";}
for(int i;i < 10; i++){ 				
cout << scoresort[0].substr (3,0) << endl;	  	  	  	  
}
				
				
				scorefile.close();
   
//  std::ostringstream o;
//  o << playerscore;
  	      
  
   
  return(PlayerScore);
}
