#include <iostream>
#include <string>


class Employee {
  private:
    std::string name, id;
    int salary;
  public:
    Employee() {}
    Employee(std::string _name, std::string _id, int _salary) : name(_name), id(_id), salary(_salary) {}
    friend bool operator <(const Employee& a, const Employee& b) {
      return a.salary < b.salary;
    }
    friend std::ostream& operator <<(std::ostream& os, const Employee& e) {
      os << "Name:   " << e.name << "\nID:     " << e.id << "\nSalary: " << e.salary << '\n';
      return os;
    }
    ~Employee() {}
};


int main() {
  const int AMOUNT = 4;
  Employee employees[AMOUNT];
  for (int i = 0; i < AMOUNT; ++i) {
    std::string name, id;
    int salary;
    int index = i + 1;
    std::cout << "\nEnter employee[" << index << "] name: ";
    std::cin >> name;
    std::cout << "Enter employee[" << index << "] id: ";
    std::cin >> id;
    std::cout << "Enter employee[" << index << "] salary: ";
    std::cin >> salary;
    employees[i] = Employee(name, id, salary);
  }
  Employee min = employees[0];
  for (int i = 1; i < AMOUNT; ++i) {
    if (employees[i] < min) {
      min = employees[i];
    }
  }
  std::cout << "\nEmployee with the smallest salary:\n----------------------------------\n" << min;
  return 0;
}
