Complete the following tasks: Design a Job class with three data fields-Job number, time in hours to complete the Job, and per-hour rate charged for the Job. • Include overloaded extraction and insertion operators that get and display a Job's values. • Include overloaded + and - operators that return integers that indicate the total time for two Jobs, and indicate the difference in time between two Jobs, respectively. • Write a main()function demonstrating that all the functions work correctly. Sample Run Enter job number 1234 Hours to complete 20 Rate per hour 12 Enter job number 4567 Hours to complete 40 Rate per hour 11 The difference between Job #1234 20 hours at $ 12 per hour and Job #4567 40 hours at $ 11 per hour is -20 hours Enter job number 6789 Hours to complete 30 Rate per hour 15 Enter job number 4563 Hours to complete 15 Rate per hour 20 The difference between Job #6789 30 hours at $ 15 per hour and Job #4563 15 hours at $ 20 per hour is 15 hours

You have a linux system that has a 1000gb hard disk drive, which has a 90gb partition containing an ext4 filesystem mounted to the / directory and a 4gb swap partition. currently, this linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. the database application and the associated data will take up over 200gb of hard disk space. in addition, these 100 users will store their personal files on the hard disk of the system. each user must have a maximum of 5gb of storage space. the department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. how much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? where would these partitions be mounted? what quotas would you implement? what commands would you need to run and what entries to /etc/fstab would you need to create? justify your answers.
