I tried to do it using the vector<string> and iterating through it to create the object but while assigning them value i am getting error

#include <bits/stdc++.h>
using namespace std;

class Student {
    public: string name;
    int rollno;
    void display() {
        cout << "Name of student is " << name <<"nHis Roll Number is " << rollno <<"n";
    }
};

int main() {
    std::vector < string > obj_name;
    for (int i = 0; i < 10; i++) {
        string temp;
        cin >> temp;
        obj_name.push_back(temp);
    }
    for (int i = 0; i < 10; i++) {
        Student obj_name[i];
    }
    for (int i = 0; i < 10; i++) {
        int x;
        cin >> x;
        obj_name[i].rollno = x;
    }
    return 0;
}
