hi, i have an assugnment where i need to read in football results from a text file output, total statistics, (games played & goals scored)output stats for a specific team, and then create a league table based on the results. the only task left is the league table. i have tried and tried to do this but i just cant get it to work it outputs every result to a new line of the array, even if its a team that has played before.
heres what ive done so far:
