What extra info is required?

IPDS Programming Exercise: January 2023 \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# This file contains all of the information necessary for completing the exercise. It is in 4 parts \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# \#\#\#A\#\#\#A\#\#\#\#\#\#\#A\# Part 1 of the file contains important information in a serles of comment boxes (11ke this one) Make sure you read all of Part 1 before proceeding Part 2 containg our program that can be used for testing your code The 'high-level' functions in thig program have already been implemented and tested. They call the ones you are required to implement for the exercise, and make use of the values your functions return. There is no need to change part:2, but you may do so if you wish to imploment your own tests. Part 2 will be removed before marking, so any changes you do make wil1 be ignored by our tester program. Part 3 of the file contains specifications and code stubs for the functions you are required to implement. For each of these functions we have provided For each of these functions we have provided a function header, giving its name and parameter list a set of comments that specify what the function should do a code stub that returns an incorrect value Your job is to provide a body for each function, which implements its specification and returns the correct data value (s) when tested You are not allowed to use any external modules in the solution of these problems (NO IMPORTS) Make sure you do not change any of the function headers only code that appears in Part 3 will be marked Part 4 currently contains an instruction that runs the main program, which can be used for testing your functions Part 4 will be removed before marking, so any changes you make to it will not be marked WHAT YOU HAVE TO DO When you have finished you should upload your revised version of the file to Canvas * Please make sure you have inserted your SRN into the code in the manner set out in Part 3 * You may change the name of the file if you wish (we suggest you make frequent backups as well) - You may submit as many times as you like (only your final submission will be marked) * Late submissions cannot be accepted * Late submissions cannot be accepted Your functions will be tested by an automated tester. * Marks are available for each test that is passed * You will get 0 marks for each test that is failed * If your code contains syntax errors it will not be possible to test it, so you may end up with 0 marks for the assignment \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# \#\# \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# \#\#\#\#\#\#\#\#\#\#F\#\#\#\#\#\#\#\#\#\#\#\#\# \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# PART 2 : SUR PROGRAM \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# The code in Part 2 will be removed before marking, so any changes you make to the code in this part of the file will not be marked lef.

The post-condition of each function specifies the relationship between the function' 9 parameters and its return value * The function must return a value that makes the post-condition true for any get of data items that makes the pre-condition true You need to write code that implements each of the functions, and test that they do what their specifications say they should You are not allowed to use any external modules in the solution of these problems (NO IMPORTS) IMPORTANT Insert your Student Registration Number (SRN) between the quotation marks in the assignment statement below: SRN =n I For example, if your SRN is 01234567 the assignment statement if should read SRN = "01234567" if should read SRN= "01234567" foption 5 (3 marks) def.
