Is it possible to put these two functions to some classes?

Question

#include <iostream>
#include <string>
using namespace std;

//Functions that assigns values to array "points" from user's input

void ReadPoints(int points[5]) {
for (int i = 0; i < 5; i++) {
cin >> points[i];
}
}
//Function that converts points to different grades

void PointsToGrade(char grade[], int points[]) {
const char *dataGrades[] = {"A","B","C","D","E", "F"};
for (int i = 0; i < 5; i++) {
if (points[i] > 90) {
grade[i] = *dataGrades[0];
}
else if (points[i] > 70 && points[i] < 90) {
grade[i] = *dataGrades[1];
}
else if (points[i] > 50 && points[i] < 70) {
grade[i] = *dataGrades[2];
}
else if (points[i] > 30 && points[i] < 50) {
grade[i] = *dataGrades[3];
}
else if (points[i] > 10 && points[i] < 30) {
grade[i] = *dataGrades[4];
}
else {
grade[i] = *dataGrades[5];
}
}
}

int main() {

//Creating an array wich is gonna be filled by user's input

int points[5];

//Calling the function ReadPoint there is sended array "points" as an argument and dispaying the values of array "points" filled by user

ReadPoints(points);
int i;
for (i = 0; i < 5; i++) {
cout << points[i] << "\t\t";
}

// Creating an array "grade" wich will be filled by grades

char grade[5];
PointsToGrade(grade, points);

for (i = 0; i < 5; i++) {
cout << grade[i] << "\t\t";
}

cout << endl;
system("pause");
return 0;
}

Answer 1

Yes, but why?

Answer 2

Learn and know how to use classes. I tried and gott many mistakes so

Answer 3

An important thing to learn while learning about classes is where to use them. Your code does not need classes. If you need practise in OOP, I suggest you search the web for exercises.

Answer 4

If u guys gonna show me how to it here I may have better understanding
