Lines not printing to screen

Hey guys, im haveing trouble here with lines outputing to the screen. Im trying to output each line of a text file to the screen, while using strtok to get each token in the line and print each one separately. Im getting only the first line of the text file and each token of that line to print out and it also seems to be ignoring the line "cout << "\nLines in File:" << count;",Also each line in the text file is echo printing to the output file which is what i want. .When i leave out the strtok function it prints each line fine to screen.
#include <iostream>
#include <fstream>
using namespace std;
const int MAX = 101;
void tokens(char*);

int main (int argc, char *argv[])
{
    ifstream data(argv[1]);
    ofstream output(argv[2]);
    int count = 0;

    cout << " Data in Text file \n" << endl;

    while (!data.eof())
    {
        count++;
        char line[MAX]=" ", copy[MAX]= " ";
       
        data.getline(line, MAX, '\n');
        output << line << "\n";
        cout << line << endl;
       
        strcpy( copy, line );
        //tokens(copy);
   

    }
    data.close();
    output.close();
    cout << "\nLines in File: " << count;
    cin.get(); 
    return 0;
}
void tokens( char *sptr)
{
        
        char *p;
         p = strtok (sptr, " ,.-");
        cout << p << endl;
          while (p != NULL)
        {
            p = strtok (NULL, " ,.-");
            cout << p << endl;
           
        }
    
    
     }
