#include <iomanip>

class Employee {
    std::string name;
    int id;
    double salary;

    // Constructor to initialize employee attributes

        name = empName;
        id = empID;
        salary = empSalary;

    // Method to display employee information
    void displayInfo() {
         std::cout << "\n\tEmployees Information Using Encapsulation in C++\n\n";
        std::cout << "\tEmployee Name: " << name << std::endl;
        std::cout << "\tEmployee ID: " << id << std::endl;
        std::cout << "\tEmployee Salary: PHP " << std::fixed <<std::setprecision(2)  << salary << std::endl;

    // Method to give a raise to the employee's salary
    void giveRaise(double raiseAmount) {
        salary += raiseAmount;
        std::cout << "\tSalary raised by PHP " <<std::fixed <<std::setprecision(2)  <<  raiseAmount << std::endl;

int main() {
    // Create an Employee object
    Employee emp("Leslie Pepito", 2002, 60412.34);

    // Display employee information

    // Give a raise of $7135.45 to the employee

    // Display updated employee information

    return 0;
