Prompt the user and read in the number of a team playing the current game, i.e. Team 1, Team 2, Team 3, etc. 2. Prompt the user and read in the number of the opponent team. It is probably helpful to think of the first team as the home team for this game, and the second team as the away team. 3. Prompt the user and read in a team’s score for the current game. Use the team’s number when asking for the score in your printf statement. 4. Prompt the user and read in the opponent’s score for that game. Again, use the opponent’s team number when asking for the score. 5. Notify the user and repeat steps 3 and 4 in the case that the user enters a negative value. 6. Calculate the points earned by each team and add it to a cumulative score. A win is worth 3 points, a draw is worth 1 point and a loss is zero points. Also update the amount of games played by each team and their goals for and against. 7. Print to the screen the following header and beneath it a line of data that corresponds to…arrow_forward
