Explanation:
The program is written in Java.
It is a bit straightforward.
The Scanner module is declared and used to collect input from the user.
The program prompts the user for each player jersey then rating.
All five players details are collected.
The program shows the output of all the entries.
From the question, we have the following observations
- The program illustrates the use of array.
- The programming language is not stated (I will answer this question using C++).
The program in C++ where comments are used to explain each line is as follows:
#include<iostream>
using namespace std;
int main(){
//This declares an integer array for the jersey numbers
int jerseyNum[5];
//This declares an integer array for player ratings
int ratings[5];
//This iterates through both integer arrays
for(int i = 0;i<5;i++){
//This prompts the user for player jersey number
cout<<"Enter player "<<(i+1)<<"'s jersey number: ";
//This gets input for player jersey number
cin>>jerseyNum[i];
//This prompts the user for player ratings
cout<<"Enter player "<<(i+1)<<"'s ratings: ";
//This gets input for player ratings
cin>>ratings[i];
}
//This prints the output header
cout<<"ROOSTER\n";
//This iterates through both integer arrays again
for(int i = 0;i<5;i++){
//This prints the rooster
cout<<"Player "<<(i + 1)<<" -- Jersey number: "<<jerseyNum[i]<<", Rating: "<<ratings[i]<<endl;
}
return 0;
} //The program ends here
