Update vaccine quantities. The system should allow the employees to select a particular vaccine and indicate either received or distributed quantity. In either case, the quantity of the selected vaccine needs to be updated accordingly in the vaccine.txt
Update vaccine quantities. The system should allow the employees to select a
particular vaccine and indicate either received or distributed quantity. In either case,
the quantity of the selected vaccine needs to be updated accordingly in the vaccine.txt
file.
E.g. Assume that the initial quantity of Pfizer vaccine in vaccine.txt file is 1 million.
When the company receives a new stock, this quantity has to be added to the existing
quantity of 1 million in the vaccine.txt file. In the case where the vaccines are distributed
to hospitals for vaccination, the distributed quantity has to be subtracted from the
quantity available in the vaccine.txt file.
Note: Whenever a vaccine is distributed to hospitals, its code and the quantity
distributed need to be recorded into a text file named as dist.txt. Each vaccine is
expected to be distributed more than once. Hence, while testing the program, there
should be at least 10 records created in the dist.txt file.
3. Search vaccine and its available quantity by using vaccine code. The system should
have a feature for employees to query a particular vaccine’s existing quantity from the
vaccine.txt file using vaccine code.
4. Produce a list of all vaccines and their distributed quantities . The system should allow
the employees to list all distributed vaccines and their accumulated quantities read from
the dist.txt file.
Note: The vaccines and their distributed quantities need to be sorted ascendingly (with
highest quantity listed first followed by second highest and so on) using Bubble sort
before displaying on the screen.
