Question

C Programming

The score table will be printed by reading the match information made between the teams.

It is not known how many teams. The team information will be kept in a dynamically changed memory area as the new team enters. The match list should also be kept in a dynamic area that is recorded as new match information is entered.

There should be 2 structs in the program.

Mac struct: Consists of 1st team name, 2nd team name, 1st team goal, 2nd team goal information.

Team struct: consists of team name (one word, 20), number of wins, number of draws, number of defeats, number of goals scored, number of goals eaten, point.

Example input: abc xyz 3 1 (Information will be entered completely and correctly.)

A single line of match information, with a space between them, 1 Team name, 2 Team name, 1.

The goal scored by the team will be entered as the goal scored by the 2nd team. In the case where the above example is the first match information entered for these teams, two teams will be identified in the abc and xyz names, and will be added to the team list, since there are no teams defined in these names yet. At the same time, a match struct will be defined, this match struct will be added to the match list, and all information of both teams in the team struct will be updated with this match information.

If the above example is not the first match information entered about the abc and xyz teams, since both teams will be defined before, these teams will be found in the teams list and their relevant information will be updated.

In summary, for the above entry, if the team has not yet been identified in these names, both teams will be identified and added to the team list. The number of victories of the ABC team will be increased by one, the number of goals scored will be increased by 3, the number of goals scored will be increased by 1, and the score will be increased by 3. The xyz team's number of defeats will be increased by 1, the goal scored will be increased by 1, the goal it has scored will be increased by 3, its score will be reduced by 1. (wins 3 points, draw 1 point, defeat -1 point). The match struct will be added to the match list.

After entering the match information, the scoreboard will be printed.

Scoreboard: The information in the team struct will be printed one after the other in the order given in the description. The scoreboard should be in descending order according to the score. In case of score equality, the team with a high average score (goals scored and goals scored) should be on the top. It can be assumed that the score and average will not be equal teams.

After the scoreboard is printed, the user will receive a sequence number from 1-teamnumber, and the matches of the team in the row entered will be listed. Unless -1 is entered, the sequence number will be read again after printing the information of a tool, and the program will end when -1 is entered. If a number between 1-teamnumber or an entry other than -1 has been made, an appropriate message will be given and the entry will be waited again.
