3. 2 Lab Demo Due Thu March 23 Lazy Computer Company has caused a new headache for their customers. Their models 1432, 1456 and 1273 have bad floppy drives. On the other hand, models 2432, 1456 and 2476 have bad CD-ROM drives and model 1762 needs a BIOS upgrade. Other 4-digit model numbers are ok. Develop a program that reads the model number of user’s PC from a data file and displays the type of problem in the machine. The program must also inform the user if the PC is found free from defects. Data file is given on the next slide. The program must use EOF controlled loop Lazy Computer Company has caused a new headache for their customers. Their models 1432, 1456 and 1273 have bad floppy drives.
