I II Write statements that accomplish each of the following. Assume that the structure struct person char lastName 15 J char firstName C 15 char age 4 J; has been defined and that the file is already open for writing. a) Initialize the file "nameage.dat" so that there are 100 records with lastName "unas- signed'', firstname and age "0" b) Input 10 last names, first names and ages, and write them to the file. c) Update a record; if there's no information in the record, tell the user "No info d) Delete a record that has information by reinitializing that particular record. I.12 (Hardware Inventory You're the owner of a hardware store and need to keep an inventory that can tell you what tools you have, how many you have and the cost of each one. Write a program that initializes the file ''hardware. dat" to 100 empty records, lets you input the data concerning each tool, enables you to list all your tools, lets you delete a record for a tool that you no longer have and lets you update any information in the file. The tool identification number should be the record number.
