Question

CAN YOU SOLVE THIS WITH EXPLANATION?

The first part of your program will read some player information from a file, format the information, put it into an array of structures, and then display that array on the screen. You will find the following structure useful: The input for your program is in a file called players.txt. Each record in the file represents one player and is made up of multiple fields that are separated by colons. The fields for each player are the player name, role, number of goals scored, number of assists, and number of shots attempted. A record in the file resembles the following: Your main function should open players.txt, check that it opened correctly, and should invoke a function (readPlayer) that reads the contents of players.txt into an array of playerlnfo structures. The readPlayer function should take as input the array of playerlnfo structures and it should return the number of players in the array. Upon return of readPlayer, your program should invoke displayPlayer, a new function, which takes the playerlnfo array and the number of elements in this array, and it displays for each player, their name, number of goals scored, number of assists, number of points, number of shots, and shooting percentage as follows: Use the following formulas for the calculated values (points and shooting %) using a function: Number of Points = Number of Goals Scored + Number of Assists Shooting Percentage = Number of Goals Scored/Number of Shots Taken * 100
