Problem:
A company requires a software application to calculate the weekly payment for its employees. The information about the employees (employees' data) is kept in a file. Each line in the file contains the employee name and number, the pay rate and the number of hours worked in a week.
The application should provide the following functionalities:
- Read the employee's data and verifies its validity (all numbers should be positive)
- Calculate the employee's weekly pay
- Print the employee's weekly pay together with the employee's data.
The pay rate for all the employees is £20.00 per hour when the working time is equal or less than 40 hours per week. For the time worked over this number of hours, the pay will be calculated doubling the actual time worked.
