A parking lot has 31 visitor spaces, numbered from 0 to 30. Visitors are assigned parking spaces using the hashing function h(k) = k mod 31, where k is the number formed from the first three digits on a visitor's license plate. a) Which spaces are assigned by the hashing function to cars that have these first three digits on their license plates: 317, 918, 007, 100, 111, 310? b) Describe a procedure visitors should follow to find a free parking space when the space they are assigned is occupied. c) A large parking-systems company would like to automate your assignment procedure for self- parking cars. You have been hired to implement a "simple" proof-of-concept program in C++, for now, customers will enter their 3 digit plate numbers and your software will assign parking space. Your implementation should find a free parking space if the original assigned space is occupied. If no spaces are free, your algorithm should say so. You need to encapsulate(embed) your algorithm in a function. You may create as many functions as you need to get the job done.

PART C.

I need help with part C, please.
Please make the codes as simple as possible for me thank you so much and Id really really appreciate this. 

I believe the task is to write a program and when people type in their 3 digit license plate, they can see which spots are open out of the 30 spots. I THINK. but I really need help on this because I could be wrong. Thank you so much. 

A parking lot has 31 visitor spaces, numbered from 0 to 30. Visitors are assigned parking spaces using
the hashing function h(k) = k mod 31, where k is the number formed from the first three digits on a
visitor's license plate.

a) Which spaces are assigned by the hashing function to cars that have these first three digits on
their license plates: 317, 918, 007, 100, 111, 310?
b) Describe a procedure visitors should follow to find a free parking space when the space they are
assigned is occupied.
c) A large parking-systems company would like to automate your assignment procedure for self-
parking cars. You have been hired to implement a "simple" proof-of-concept program in C++, for
now, customers will enter their 3 digit plate numbers and your software will assign parking
space. Your implementation should find a free parking space if the original assigned space is
occupied. If no spaces are free, your algorithm should say so. You need to encapsulate(embed)
your algorithm in a function. You may create as many functions as you need to get the job done.
