Just write the C++ code uand comments I will do the dowlnloading of the file so dont worry
Q: Baseball is a sport with constantly changing statistics. Every time a player is at bat, their statistics change. Create a C++ program to control a team’s statistics. 1. Import the team's current statistics. To do this, create an array of structures that includes the player’s NUMBER, NAME, POSITION, AT BATS, BATTING AVERAGE, STRIKEOUTS, ON BASES, and HOMERUNS. Now import the Stats.txt file (DOWNLOAD THIS FILE and store it in your project folder) and write the file contents to the array of structures. The contents of each line of the file is written in the order of the stats above and are separated by a space. 2. Ask the user to enter the current player at bat. Have the user enter the player’s number and search the array to find the matching player of structures and output that player’s stats. NO INPUT VALIDATION IS NEEDED. 3. Ask the user to enter whether the player strikes out, has a base hit, hits a homerun, or gets out. (Assume they enter correctly and no WALKS or ERRORS.) Now adjust the player's stats. Batting average = (homeruns + on_base) / at_bats a. Strike out: at_bats += 1, strikeouts +=1 b. Base hits: at_bats += 1, on_base += 1 c. Homerun: at_bats += 1, homeruns += 1 d. Out: at_bats +=1 4. Finally, a baseball inning ends after three outs. Make a new file “UpdatedStats.txt” that contains the new states based on what has happened in the inning. Make sure your program can update AT BATS, BATTING AVERAGE, STRIKEOUTS, ON BASES, and HOMERUNS in the “UpdatedStats.txt” file. If the code fails to create or open a file for writing, have the program print an error message “Unable to pen file. New file has not been written.”
Sample Output:

***HINTS***
For importing the file:
ifstream inputFile;
inputFile.open("Stats.txt");
STATS * roster= new STATS [ROSTER_SIZE]; // STATS is the struct name.
For updating the stats:
Strikeout :
roster[cp].average=(double(roster[cp].on_bases)+
double(roster[cp].homeruns))/(double(roster[cp].at_bats + 1));
Base hit:
roster[cp].average=((double(roster[cp].on_bases + 1)+
double(roster[cp].homeruns))/(double(roster[cp].at_bats + 1));
Homerun:
roster[cp].average=(double(roster[cp].on_bases)+ double(roster[cp].homeruns +
1))/( double(roster[cp].at_bats + 1));
Out:
roster[cp].average=(double(roster[cp].on_bases)+double(roster[cp].homeruns))/(f
loat(roster[cp].at_bats + 1));
For creating the output file:
ofstream newStats("UpdatedStats.txt");
Setting precision of 3 decimals in output file:
myFile << std::setprecision(3) << ...
