My first comment is that your float variable cost should be an array. (After all, each song has a different cost, right?) Here's a short sample I wrote for someone with a similar question. Study it and see if it helps.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main()
{
    string str[30][3];
    ifstream myfile("testfile.txt");
    int a = 0;
    int b = 0;
    if(!myfile) //Always test the file open.
    {
                cout<<"Error opening output file"<<endl;
                system("pause");
                return -1;
    }
    while(!myfile.eof())
    {
      getline(myfile,str[a][b],' ');
      if(a ==29)
      {
           a=0;
           ++b;
           getline(myfile,str[a][b],' ');
      }
      a++;
    }
    system("pause");
}
      


testfile.txt
a b c d e f g h i j k l m n o p q r s t u v w x y z aa bb cc dd

31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60

This was written to store a file of columns and rows into a multidimensional array, but the same general principals apply. If you have any problems, just post back with your question.

with the following code it stores the entire file into first element of array, how do i have each string in file into seperate element, also how would i put cost variable into an array.

enum mediaType {CD, TAPE, MP3};
struct Song
{char title[20];
 char artist[20];
 mediaType medium;
 float cost;
};

#include <iostream>
#include <fstream>
#include <string>

using namespace std; 



int main()
{
    
    
    string Song[4][200];
    
    ifstream myfile;
    
    myfile.open("song.txt");
    
    int a = 0;
    int b = 0;
    
    if(!myfile) //Always test the file open.
    {
                cout<<"Error opening output file"<<endl;
                system("pause");
                return -1;
    }
    
    while(!myfile.eof())
    {
      getline(myfile,Song[a][b],' ');
      if(a ==4)
      {
           a=0;
           ++b;
           getline(myfile,Song[a][b],' ');
      
      }
      a++;
   
    cout<<Song[0][0];
    
    }
    

    
    system("pause");
}

i modified code and the strings from the txt file goes into the array, but it prints it multiple times and crashes. Can someone tell me why it crashes? might be because of the break?

enum mediaType {CD, TAPE, MP3};
struct Song
{char title[20];
 char artist[20];
 mediaType medium;
 float cost;
};

#include <iostream>
#include <fstream>
#include <string>

using namespace std; 



int main()
{
    
    
    string Song[4][200];
    
    ifstream myfile;
    
    myfile.open("song.txt");
    

    
    if(!myfile) //Always test the file open.
    {
                cout<<"Error opening output file"<<endl;
                cin.get();
                return -1;
    }

    long a = 0;
    
    while(!myfile.eof())
    {            
        for(long b = 0; b < 4; b++)
        {
            
            if (b == 3)
            {
                  getline(myfile,Song[a][b],'\n');
                  break;
            }
            
            getline(myfile,Song[a][b],' ');
            
              
        }
        cout << Song[0][0] << ' ';    
        a++;
        
    }
    
    cin.get();
}
