Answer 1

Explanation:

Here is the code which asks for the number of students from the user and then each student's score and name is asked and sum is taken for the scores and the highest score is also detected.

Then, average, highest score are printed and then difference of both is also printed.

Code:

#include <iostream>

using namespace std;

int main()
{
int n;
cout<<"Please enter the number of students: ";
cin>>n;
  
string name_highest = "";
int highest = -1;
  
int sum = 0;
  
int i=0;
  
while (i < n) {
  
string s;
int score;
  
getline(cin, s);
  
cout<<"Enter the student name: ";
getline(cin, s);
cout<<"Enter the score: ";
cin>>score;
sum+= score;
if(highest<score)
{
name_highest = s;
highest = score;
}
  
i++;
}
  
cout<<name_highest<<endl;
cout<<"score is "<<highest<<endl;
  
float avg = (float)sum/(float)n;
cout<<"the average is "<<avg<<endl;
  
cout<<"the difference is "<<(highest-avg)<<endl;

return 0;
}
