Display Student ID and highest score from an array - c++

Question

I am having issues figuring out how to properly display a student's ID, out of 10 students, along with the highest score. For examle, if student 4 had the highest score if would display said student's ID and their score. I would like to add the student's first and last name as well, if possible. My code is as follows:
// HW2.cpp : This file contains the 'main' function. Program execution begins and ends there.
#include <iostream>
using namespace std;
double TestScore(double score);
struct studentType {
string studentFName;
string studentLName;
double testScore;
int studentID;
double highScore;
};
int main()
{
// # of students
studentType student[10];
// For loop to get user input for the 10 students
for (int i = 0; i < 10; i++) {
cout << "Student ID: ";
cin >> student[i].studentID;
cout << "Student First Name: ";
cin >> student[i].studentFName;
cout << "Student Last Name: ";
cin >> student[i].studentLName;
cout << "Student's Test Score: ";
cin >> student[i].testScore;
cout << endl;
//Calls TestScore function
student[i].testScore = TestScore(student[i].testScore);
}
//Displays student ID and score v code that I need help on
//cout <<student[i].studentID << " has the highest score, which is "<< TestScore;
}
double TestScore(double score)
{
double newScore = 0;
//Determines student with highest score
for (int n = 0; n < 10; n++) {
if (score > newScore)
{
newScore = score;
}
}
return newScore;
}
It needs to :
1) read the students’ data into the array.
2) find the highest test score.
3) print the names of the students having the highest test score.

Answer 1

Your TestScore function doesn't really do anything. I've modified your code to have a function which returns the index of the student with the best score. Using this index, you can then access that element of the array, and print out its details.
#include <iostream>
using namespace std;
struct studentType {
string studentFName;
string studentLName;
double testScore;
int studentID;
double highScore;
};
int getBestStudent( studentType student[10] );
int main() {
// # of students
studentType student[10];
// For loop to get user input for the 10 students
for ( int i = 0; i < 10; i++ ) {
cout << "Student ID: ";
cin >> student[i].studentID;
cout << "Student First Name: ";
cin >> student[i].studentFName;
cout << "Student Last Name: ";
cin >> student[i].studentLName;
cout << "Student's Test Score: ";
cin >> student[i].testScore;
cout << endl;
}
// Displays student ID and score v code that I need help on
int best = getBestStudent( student );
cout <<student[best].studentFName << " " << student[best].studentLName << " has the highest score, which is "<< student[best].testScore;
}
int getBestStudent( studentType student[10] ) {
int best = 0;
//Determines student with highest score
for ( int n = 1; n < 10; n++ ) {
if ( student[n].testScore > student[best].testScore ) {
best = n;
}
}
return best;
}```
