Answer 1

Answer:

1. #include <iostream>
2. using namespace std;
3. int main()
4. {
5.    int highest = 0;
6.    int score;  
7.    do{
8.        cout<<"Input a score: ";
9.        cin>>score;
10.        
11.        if(score > highest){
12.            highest = score;
13.        }    
14.    }while(score >= 0);
15.    
16.    cout<<highest;
17.    return 0;
18. }

Explanation:

Firstly, create a variable highest and initialize it with zero (Line 5). Next, create a do while loop (Line 7 - 14). Within the loop prompt user to input a score (Line 8-9) and if the current score is higher than the highest variable, assign the score to highest variable (Line 11 - 13).

After finishing the loop when user put in any negative value, the program shall be able to print out the highest input score (Line 16).
