Explanation

Class Definitions:
- Employee Class:
  - Private Members:
    - name: The name of the employee.
    - performance: The performance rating of the employee (0 to 100).
  - Public Methods:
    - Employee(std::string name, int performance): Constructor initializes the employee’s name and performance rating.
    - std::string getName() const: Returns the employee’s name.
    - int getPerformance() const: Returns the employee’s performance rating.
    - void setPerformance(int newPerformance): Sets a new performance rating.
- HRSystem Class:
  - Private Members:
    - employees: A vector storing Employee objects.
  - Public Methods:
    - void addEmployee(const Employee& employee): Adds an Employee to the system.
    - void evaluatePerformance(): Simulates performance evaluation by randomly changing the performance rating of each employee. The change is between -10 and +10, clamped to a range of 0 to 100.
    - void printEmployees() const: Prints the names and performance ratings of all employees.
main Function:
- Initializes the random seed with the current time.
- Creates an HRSystem object and adds several employees.
- Prints the initial performance of the employees.
- Simulates performance evaluation over a number of months, updating and printing employee performance after each month.
