2. In a game called DuckHunting, players must shoot the ducks as they appear. A binary file called "scores.dat" contains a sequence of 4 player's scores. Each record (a score) consists of the C structure: struct score{ int ducksKilled; int ducksMissed; int points; int rank; } Write a C-program that calculates the total points gained and the rank of each player. Your program should use two processes, A and B, where: Process A calculates the number of points each player scored, and updates points in each data structure. Two points are awarded for each duck killed and 1 point is taken away for each duck missed. Process B calculates the rank of each of the 4 players, and updates rank in each data structure Use semaphores to ensure that the processes complete the task correctly, that is, both synchronization of the processes and protection of the critical region are required. The use of pipes are not permitted.
