**Problem :**

A *class* defines a blueprint for an object. We use the same syntax to declare objects of a class as we use to declare variables of other basic types. For example:

```
Box box1; // Declares variable box1 of type Box
Box box2; // Declare variable box2 of type Box
```

Kristen is a contender for valedictorian of her high school. She wants to know how many students (if any) have scored higher than her in the * 5* exams given during this semester.

Create a class named * Student* with the following specifications:

- An instance variable named
to hold a student’s`scores`

exam scores.`5`

- A
*void input()*function that reads

integers and saves them to*5*.`scores`

- An
*int calculateTotalScore()*function that returns the sum of the student’s scores.

**Input Format** :

Most of the input is handled for you by the locked code in the editor.

In the `void Student::input()`

function, you must read * 5* scores from stdin and save them to your

*instance variable.*

`scores`

**Constraints** :

*1 <= n <= 100*`0 <= examscore <= 50`

**Output Format** :

In the `int Student::calculateTotalScore()`

function, you must return the student’s total grade (the sum of the values in * scores*). The locked code in the editor will determine how many scores are larger than Kristen’s and print that number to the console.

**Sample Input** :

The first line contains * n*, the number of students in Kristen’s class. The

*subsequent lines contain each student’s*

`n`

*exam grades for this semester.*

`5`

```
3
30 40 45 10 10
40 40 40 10 10
50 20 30 10 10
```

**Sample Output** :

`1`

**Explanation** :

Kristen’s grades are on the first line of grades. Only * 1* student scored higher than her.

## Solution :

```
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
#include <cassert>
using namespace std;
class Student {
private:
int sum;
int num[5];
public:
void input() {
for (int i = 0; i < 5; i++) {
cin >> num[i];
}
}
int calculateTotalScore() {
for (int i = 0; i < 5; i++) {
sum += num[i];
}
return sum;
}
};
int main() {
int n; // number of students
cin >> n;
Student *s = new Student[n]; // an array of n students
for(int i = 0; i < n; i++){
s[i].input();
}
// calculate kristen's score
int kristen_score = s[0].calculateTotalScore();
// determine how many students scored higher than kristen
int count = 0;
for(int i = 1; i < n; i++){
int total = s[i].calculateTotalScore();
if(total > kristen_score){
count++;
}
}
// print result
cout << count;
return 0;
}
```
