The program is an illustration of arrays.
Arrays are used to hold multiple values in one variable.
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 array of three elements for the three ratings
int ratings[3];
//This initializes the sum of the ratings to 0
int total = 0;
//The following iteration gets input for the three ratings
for(int i = 0; i<3;i++){
cin>>ratings[i];
//This calculates the sum of all inputs
total+=ratings[i];
}
//This declares and initializes the lowest and the highest ratings
int lowest = ratings[0], highest = ratings[0];
//This iterates through the array
for(int i = 1; i<3;i++){
//The following if condition determines the lowest rating
if (lowest > ratings[i]){ lowest = ratings[i]; }
//The following if condition determines the highest rating
if (highest < ratings[i]){ highest = ratings[i]; }
}
//This prints the output header
cout<<"The ratings are: ";
//The following iteration prints the three ratings
for(int i = 0; i<3;i++){
cout<<ratings[i]<<" "; }
//The prints the highest ratings
cout<<endl<<"Highest: "<<highest<<endl;
//The prints the lowest rating
cout<<"Lowest: "<<lowest<<endl;
//The prints the average rating
cout<<"Average: "<<total/3<<endl;
return 0;
}
At the end of the program, the ratings entered, the highest rating, the lowest rating, and the average of the ratings are printed.
