1. Both employee and employer must contribute a certain percentage of the employees salary toward Employees' Provident Fund. The percentage of the contribution is shown below: Employees Age Employee Rate (%) Employer Rate (%) 55 and below 20 17 Above 55 to 60 13 13 Above 60 to 65 7.5 9 Above 65 5 7.5 However, the contribution is subjected to a salary ceiling of RM10,000. In other words, if an employee earns RM10,500, only RM10,000 attracts employee's and employer's contributions, the remaining RM500 does not. Write a program that can calculate the employee's, employer's and total contributions (all amounts must be rounded to 2 decimal places). Your program must be able to repeatedly perform the calculations until the user enters -1 for the salary. An example of the programs running is given below (Note: The bold texts below are inputs entered by the user)
