Suppose that only 80% of the student records from exercise 16.28 have a value for phone, 85% for major_dept_code, 15% for minor_dept_code, and 90% for degree_program; and suppose that we use a variable-length record file. each record has a 1-byte field type for each field in the record, plus the 1-byte deletion marker and a 1-byte end-of-record marker. suppose that we use a spanned record organization, where each block has a 5-byte pointer to the next block (this space is not used for record storage). a. calculate the average record length r in bytes. b. calculate the number of blocks needed for the file.

Write a program that has a conversation with the user. the program must ask for both strings and numbers as input. the program must ask for at least 4 different inputs from the user. the program must reuse at least 3 inputs in what it displays on the screen. the program must perform some form of arithmetic operation on the numbers the user inputs. turn in your .py file as well as a screenshot of your program's output. include comments in your code to explain how it works an example program run might look like (have fun with this and be creative): ‘what is your name? ’ “josh” ‘, josh. what is your favorite color? ’ “green” ‘mine too. do you also like ice cream? ’ “no” ‘josh, how old are you? ’ “40” ‘ and how many siblings do you have? ’’ “3” ‘that means you are one of 4 kid(s). is green the favorite color of anyone else in your house? ’
