Reading and printing N student's details

This program will explain how to read and print multiple student details using Array of Objects.

Array of objects program in C++

// C++ program to create student class, read and print N student's details
// (Example of array of objects)

#include <iostream>
using namespace std;

#define MAX 10

class student {
private:
    char name[30];
    int rollNo;
    int total;
    float perc;

public:
    //member function to get student's details
    void getDetails(void);
    //member function to print student's details
    void putDetails(void);
};

//member function definition, outside of the class
void student::getDetails(void)
{
    cout << "Enter name: ";
    cin >> name;
    cout << "Enter roll number: ";
    cin >> rollNo;
    cout << "Enter total marks outof 500: ";
    cin >> total;

    perc = (float)total / 500 * 100;
}

//member function definition, outside of the class
void student::putDetails(void)
{
    cout << "Student details:\n";
    cout << "Name:" << name << ",Roll Number:" << rollNo << ",Total:" << total << ",Percentage:" << perc;
}

int main()
{
    student std[MAX]; //array of objects creation
    int n, loop;

    cout << "Enter total number of students: ";
    cin >> n;

    for (loop = 0; loop < n; loop++) {
        cout << "Enter details of student " << loop + 1 << ":\n";
        std[loop].getDetails();
    }

    cout << endl;

    for (loop = 0; loop < n; loop++) {
        cout << "Details of student " << (loop + 1) << ":\n";
        std[loop].putDetails();
    }

    return 0;
}

Output

    Enter total number of students: 2
    Enter details of student 1:
    Enter name: Mike
    Enter roll number: 101
    Enter total marks outof 500: 456
    Enter details of student 2:
    Enter name: Mock
    Enter roll number: 102
    Enter total marks outof 500: 398

    Details of student 1:
    Student details:
    Name:Mike,Roll Number:101,Total:456,Percentage:91.2Details of student 2:
    Student details:
    Name:Mock,Roll Number:102,Total:398,Percentage:79.6
