guys, i was making a employee project using classes and arrays and used loops and two functions, but when i am running it it is showing me an many errors i dont know whats wrong in this code
this is my code:

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

class employee //class of employee
{
  int id;      //id of a employee
  int salary;  //salary of a employee
  string name; //name of employee

public:
  void setid(void) //function to set id of employee
  {
    cout << "enter the name of a employee :\n";
    cin >> id << name;
    cout << "enter the id of a employee :\n";
    cin >> id << endl;
    cout << "enter the salary of a employee :\n";
    cin >> salary << endl
                  << endl;
  }

  void display(void) //to display a data of employee.
  {
    cout << "the name of employee is:" << name;
    cin >> id << endl;
    cout << "id of this employee is: " << id;
    cin >> id << endl;
    cout << "salary of this employee is: " << id;
    cin >> salary << endl;
  }
};

int main()
{
  employee all[4]; //creating array to store 4 employee
  for (int i = 0; i < 4; i++)
  {
    all[i].setid();
    all[i].display();
  }

  return 0;
}
