1. Consider the array given below. Write a C program that must be able to sort
the elements in the array. You must use pointers in your code to work with the
arrays. The sort functionality must be implemented as a separate function
named “sort_numeric()”
Array for your evaluation

[10, 0.25, -2342, 12123, 3.145435, 6, 6, 5.999, -2, -5, -109.56]
If given user input A or a: sort in Ascending order
If given user input D or d: sort in Descending order

2. Consider the list of names given below. Write a C program that will first create
a string array that will contain this list and then sort the elements in the array
as per alphabetical order. You must use pointers in your code to work with the
arrays. The sort functionality must be implemented as a separate function
named “sort_alphabetic()”. The program can be case insensitive (i.e. capital
or small letters are treated the same).

If given user input A or a: sort in alphabetical order (a comes first)
If given user input D or d: sort in reverse alphabetical order(z comes first)
3. Repeat Question 1 or Question 2, considering that the number of elements
can potentially increase. That is, the size of the array will be unknown at the
start of the program. Note that the requirement of using pointers still holds.
Show proof of evaluation of your program being able to work for more than 10
entries. Show 5 evaluation trials in your submission. You can pick any number
of entries between 10 and 30 for your trials.

(Hint: To solve this, use dynamic memory allocation, where you will NOT treat
the input array as a known or finite size. Allocate memory space (e.g.
malloc()) as and when the number of elements in the list increases).

4. Using C programming and using Structures or Unions in your program, build a
COVID vaccine registration form where any user can register by filling in their
First Name, Last Name, Date of Birth (mm/dd/yyyy), Sex, Dose number (1 or
2), Date of previous dose, Type of vaccine (Pfizer, Moderna,
Johnson&Johnson), Residential zipcode.
Upon registration, the system must output a 8 letter alphanumeric code that
will be unique to that user.

The code is generated as
Add functionality in your program such that it will display all the
user’s information on the screen (one item in each line).
Show an evaluation trial for registering at least 10 users. For registration, ,for
relevant questions, users must choose values based on the options provided
(e.g. sex; options must be Male/Female/Do not wish to identify)
(Hint: Write a program that contains main(), register(), generate_code() and
retrieve() functions, at the least).
