Write a C++ program to display Names, Roll No., and grades of 3 students who have appeared in the examination. Declare the class of name, Roll No. And grade. Create array of class objects. Read and display the contents of the array.

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

class Student {
public:
    string name;
    int rollNo;
    char grade;

    void readData() {
        cout << "Enter Name: ";
        cin.ignore();
        getline(cin, name);

        cout << "Enter Roll Number: ";
        cin >> rollNo;

        cout << "Enter Grade: ";
        cin >> grade;
    }

    void displayData() {
        cout << "Name: " << name << endl;
        cout << "Roll No: " << rollNo << endl;
        cout << "Grade: " << grade << endl;
    }
};

int main() {
    Student students[3];

    cout << "Enter details of 3 students:\n";
    for (int i = 0; i < 3; i++) {
        cout << "\nStudent " << i + 1 << ":\n";
        students[i].readData();
    }

    cout << "\n--- Student Details ---\n";
    for (int i = 0; i < 3; i++) {
        cout << "\nStudent " << i + 1 << ":\n";
        students[i].displayData();
    }

    return 0;
