CSCI 1105 – Fall 2020
To complete this assignment, you will need to know about:
• Basic Input
• Conditionals
• Comparing different data types
• Boolean Variables
• Simple Input Validation
• Loops
Your code must compile. If it does not compile, you will receive a 0 (zero) on that portion of the
assignment, and no partial marks will be given.
Remember that students who hardcode their outputs to match the test cases in Mimir will
receive a zero on the entire assignment.
Grading Scheme: Please see the grading scheme at the end of this document.
Variable names: We expect students to use descriptive variable names and methods names plus
correct capitalization in the code they submit. This will be graded as it is important for code
readability.
Comments: We expect students to use comments in their code and include a header comment
in all assignment files! This will be graded as it is important for code readability. The header
comment should be placed first in the file and must conform to the following format:

Problem 1 – Managing Inventory (Warmup)
The graphics card manufacturer Nvidia was recently criticized for the way they managed their
inventory of the newly release RTX 3080 and 3090 graphics cards.
To help Nvidia, you will create a program that keeps track of sales and restock of Nvidia's 3080
graphics cards. Your program will keep a record of the current inventory of the cards, and it will
not allow new purchases when there are more than 50 cards (included) in backorder1
Your program will read integers representing either restock (adding new items to the inventory)
or sales until it reads a 0 telling it to close the store and report.
• Positive integers mean that new cards arrived in the stock (that is, an increase in the
inventory)
• Negative integers mean that the store sold cards that day
• '0' means that the store is closed, and you should print how many cards are left in stock
or how many are in backorder.
Backorder Policy: If they have more than 50 cards (included) in backorder, the store will refuse
to sell new cards until the inventory has been restocked to less than 50 cards in backorder. If a
customer tries to purchase a card in this situation, your program should print an error message
according to the example below.
The store always open with a zero inventory of cards
Examples:
Input Output
10 10 -4 -4 0 Thank you! Store is now closed.
Inventory: 12
9 -20 -30 -4 -10 -5 0 Im sorry, we cannot take new orders as
our backorder list is >50
Thank you! Store is now closed.
Inventory: -55
9 -20 -10 -4 -10 -5 0 Thank you! Store is now closed.
Inventory: -40
1 A product in backorder means that the customer payed for it but did not receive the product yet since it was out
of stock.
Problem 2 – The Flu Shot
As we approach winter, flu vaccinations become one of the priorities for public health officials.
A vital public health metric is to know the percentage of the population vaccinated.
In this problem, you will write a program that will keep track of the Atlantic Provinces (NS, NB,
NFL, PEI). Your program will read vaccination reports numbers from each province (multiple
reports are possible) and each province's total population. It will then print the % of the
population vaccinated. It will also print a warning for any region that is below 80% vaccinated.
The input is as follows:
- You will read an integer and a word containing the numbers of newly vaccinated
people and their province (e.g. 80 NS)
o If the number is negative, you should ignore the input
- You will read a 0 (zero) informing your program that there are no new vaccination
reports
- Then you will read an integer and province informing you of the total population of
each province.
- Please note that the names of the provinces will always be correct. Do not assume
any order
Your program will print the information according to the examples below. Please limit your
decimal points to two digits using the printf method. You must also left pad your number with
up to 3 zeros.
Hint: the printf syntax for floats goes as follows: %width.decimalsf
Hint2: You will have to print a %, which needs to be escaped. You do not escape % with \

Grading Scheme
Each problem on the assignment will be graded based on three criteria:
Functionality
"Does it work according to specifications?" This is determined in an automated fashion by
running your program on a number of inputs and ensuring that the outputs match the expected
outputs. The score is determined based on the number of tests that your program passes.
Quality of Solution
"Is it a good solution?" This considers whether the solution is correct, efficient, covers boundary
conditions, does not have any obvious bugs, etc. This is determined by visual inspection of the
code. Initially full marks are given to each solution and marks are deducted based on faults
found in the solution.
Code Clarity
"Is it well written?" This considers whether the solution is properly formatted, well-
documented, and follows coding style guidelines. A single code clarity score is assigned for all
solutions. If your program does not compile, it is considered non-functional and of extremely
poor quality, meaning you will receive 0 for the solution.
