Answer 1

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


struct Students
{
    int roll{ 0 };
    string name;
    string departament;
    int course{ 0 };
    int  year{ 0 };
};
void setStudent(Students *p, int n, int num) 
{
    string line;
    cout << "Enter student data number " << num << endl;
    num = num - 1;
    cout << "Enter roll number student:";
    cin >> p[num].roll;
    cin.get();
    cout << "Enter name student:";
    getline(cin, line);
    p[num].name = line;
    cout << "Enter the student department:";
    getline(cin, line);
    p[num].departament = line;
    cout << "Enter the student's course of study:";
    cin >> p[num].course;
    cout << "Enter the year the student entered:";
    cin>> p[num].year;
}

}
int main()

    Students group[10];
    //enter dataset all students
    for (int i = 1; i < 11; i++) 
    {
        setStudent(group, 10, i);
    }
    // output names of all students who joined in a particular year.
    int year_choise;

    cin >> year_choise;


    for (int i = 0; i < 10; i++)

        cout << "displaying the names of students who joined in ." << year_choise << "years:" << endl;
        if (group[i].year == year_choise)
        {
            cout << group[i].name<<endl;
        }
    }
    // data of the student whose roll number is entered
    int roll_choise;
    cin >> roll_choise;
    for (int i = 0; i < 10; i++) 
    {
        if (group[i].roll == roll_choise) 
        {
            viewStudent(group, 4, i + 1);
        }
    }
    return 0;
