Write SQL codes according to the requirements given. Tables are imaginary, column names can be made up. 1. List the item ID, description, unit price, and category for each item that has a unit price greater than the unit price of every item in category CAT. Use either the ALL or ANY operator in your query. (Hint: Make sure you select the correct operator.)
2. For each item, list the item ID, description, units on hand, invoice number, and quantity ordered. All items should be included in the results. For those items that are currently not on an invoice, the invoice number and quantity ordered should be left blank. Order the results by item ID.
3. If you used ALL in question 1 repeat the exercise using ANY. If you used ANY, repeat the exercise using ALL, and then run the new command. What question does the new command answer?

Write a function processpeople() that takes the name of a file as a parameter. each line of the file corresponds to information about a person. in particular a line contains either a name (in the form lastname,firstname with no spaces in it) or a name (lastname,firstname) and a year. the function will process the file, creating a person object for each line in the file. the function will print information about each line as it processes it, as well as appending the new person object into a list. make sure to use person methods to display information rather than recreating the work you did for the first problem. once the entire file has been processed, the function returns the list of person objects created from the file. if the file is empty, the function should return an empty list. if the input file cannot be opened, the function should print a message to that effect and then return an empty list. the following shows what would be displayed for two example files which have been provided in the link. the file none.txt does not exist. note that your function must work on an arbitrary file that consists of valid lines. you cannot assume anything about the file except that it contains lines that have the format described above.

3. (5 points) describe what would be printed by the code below or what error would occur. const char* cstr = "0123456"; const char* ptr = & cstr[4]; cout < < ptr[-1] < < ptr < < endl; 1 4. (5 points) theseus has been trapped in a maze with a minotaur, which is trying to capture him. each round, theseus and the minotaur move through the maze; theseus towards the exit, and the minotaur towards theseus. theseus can move in any of the four cardinal directions, or he can wait for a round to see how the minotaur moves. write code that creates a data type to represent the possible moves that theseus could make.
