Define a class Benefit, described as below:

Data Members:
Salary, Bonus and Amount (double), Exp (float)

Member Methods:
Benefit (double, float) — Parameterized constructor to initialize Salary and Exp
Evaluate() — To evaluate the value of Amount using the formula:
Amount = Salary + Bonus, based on the experience of the employee:

Experience in years	Bonus
More than 3 but less than 5	10% of Salary
More than equal to 5 but less than 10	15% of Salary
More than equal to 10 but less than 20	20% of Salary
More than equal to 20	30% of Salary

Display () - To print all the data members.

Write a main method to create an object of the class Benefit and call the above methods.

public class Benefit

    double salary;
    double bonus;
