infile arrays

[Pheonix]

How would one infile an array of numbers from a .txt file? i am trying to make a subprogram that infiles data stored in a .txt file and slightly edits the data based on the result of the program, without changing anything else.

This is what I currently have, it is printing the edited results, however, it is erasing all previous data and restoring it to 0.

  void record(){
	ifstream infile;
	infile.open("Balance.txt");

	j = 0;

	while (j < 12){

		k = 0;

		while (k < 12){
			infile >> matchup[k][j]; /* this is probably where my error is, I'm not sure how to infile a specific location of a .txt file*/
			k++;
			

		}
		j++;
	}
	

	infile.close();

	matchwin = matchwin - 1;
	matchloose = matchloose - 1;

	matchup[matchloose][matchwin]++;

	ofstream outfile;

	outfile.open("Balance.txt");

	j = 0;

	while (j < 12){

		k = 0;

		while (k < 12){
			outfile << matchup[k][j];
			k++;

		}
		outfile << endl;
		j++;
		cout << endl;
	}

	outfile.close();
}
