Question

Use basic C++

3. A text file, superstars.txt, contains statistics on cricket players. For each player, the file contains the player's first name, last name, number of matches played, total number of runs scored, number of times the player scored 100 runs in a match, and the number of wickets taken. The last row of data in the file contains the word "END" only. Some rows are shown below 30 11867 164 Chanderpaul Shivnarine 34 11912 130 Lara Brian 73 15 7214 Gayle 103 Chris [1 mark] (a) Declare a struct of type Player to store each player's data. (b) Write a function, readPlayers, which reads the data from the file and stores it in an array of Player structs passed as a parameter. The function should return the amount of structs stored in the array. Assume that there are at most 100 players. [4 marks] (c) Write a function, displayPlayer, which accepts a Player struct as a parameter and displays the information for that player on the monitor. [2 marks] (d) Write a function, maxRuns, which a elements in the array as parameters, and returns the index of the player who scored the most runs (assume only one exists). ount of array of Play ts and the [4 marks] (e) Write a function, searchPlayer, which accepts an array of Player structs, the amount of elements in the array, and a last name as parameters and returns the index of the player with that last name or -1 if that player does not exist [4 marks] lo duit (f Write a segment of code that declares an array of Player structs, reads the data from the file, superstars.txt into the array, and finds and displays the player who scored the most runs. The code should also display information for the player with last name "Richards" if that player exists. [5 marks] NB: You can use either the string type or C-strings in this question.

Answer 1

solution:
This solution has an explanation, full c++ code, comments with code and screenshot of

execution of the program for your clear and better understanding.

EXPLANATION:

Before going to directly answer first let's see the approach for solving this problem.

First, make a .txt file and store required no of players info.

Then make a main.cpp and construct a struct of given structures with first name, last name, total matched played,etc..

and make other functions as well for respective functionality and then call from main as required

Now for more visualization see the code below:

superstars.txt :

shivnarine Chanderpaul 164 11867 30 9
Brian lara 130 11912 34 0
Chris gayle 103 7214 15 73

c++ code :

// header files

#include<iostream>

#include<string>

#include<fstream>

using namespace std;

#define MAX 100

// Player str

struct Player {

string fName;

string lName;

int numOfMatchedPlayed,totalRunsScored;

int numOfCenturies,WicketsTaken;

};

// to read from file

int readPlayers(struct Player p[]) {

int count = 0;

string fname,lname;

int matchplayed,totalrun,totalcenturies,wickets;

// file ptr

fstream fp;

// open a file

fp.open("superstars.txt");

// read while Not end of file

while (fp>>fname>>lname>>matchplayed>>totalrun>>totalcenturies>>wickets)

{ // store into Player str

p[count].fName=fname;

p[count].lName=lname;

p[count].numOfMatchedPlayed = matchplayed;

p[count].totalRunsScored =totalrun;

p[count].numOfCenturies = totalcenturies;

p[count].WicketsTaken = wickets;

count++;

// cout<<"\n"<<fname<<" "<<lname<<" "<<matchplayed<<" "<<totalrun<<" "<<totalcenturies<<" "<<wickets;

}

// return total no of players from file

return count;

}

// check for max run

int maxRuns(Player p[],int n){

int maxRunIndex = -1;

int maxRun = -1; // assume initially max = -1

for(int i=0;i<n;i++)

// update max run when found new maximum from earlier

if(maxRun<p[i].totalRunsScored){

maxRunIndex = i;

maxRun = p[i].totalRunsScored;

}

// return index of max run

return maxRunIndex;

}

// to diplay info of player

void displayPlayer(Player p){

cout<<"\nFirstName : "<<p.fName<<"\nLastName : "<<p.lName<<"\nmatch Played = "<<p.numOfMatchedPlayed<<"\nTotal scored Run = "<<p.totalRunsScored<<"\nTotal centuries = "<<p.numOfCenturies<<"\nNum. of Wickets Taken = "<<p.WicketsTaken;

}

// to search for player

int searchPlayer(Player p[],int n,string lname){

for(int i=0;i<n;i++)

// searching from last name

if(p[i].lName == lname)

return i;

return -1;

}

// main function

int main()

{

// string to search

string lname = "lara";

// array of player str

struct Player p[MAX];

// calling function to read file

int x = readPlayers(p);

// calling function to know index of max run

int index = maxRuns(p,x);

// calling function to search a player

int lNameFoundIndex = searchPlayer(p,x,lname);

cout<<"\nPlayer who scored Max Run : "<<p[index].fName<<" "<<p[index].lName<<endl;

// if player with last name found then display info of that player

if(lNameFoundIndex>=0){

cout<<"\nInfo. of player with last name : "<<lname<<endl;

displayPlayer(p[lNameFoundIndex]);

}

else cout<<lname<<" NOT FOUND";

cout<<endl;

return 0;

}
