Please use C **COVID Vaccine Registration Program Using C**Develop a C program utilizing Structures or Unions to create a COVID vaccine registration form. Users should provide the following information:- **First Name**- **Last Name**- **Date of Birth** (format: mm/dd/yyyy)- **Dose Number** (1 or 2)- **Date of Previous Dose**- **Type of Vaccine** (e.g., Pfizer, Moderna, Johnson & Johnson)- **Residential Zip Code****Unique Code Generation:**Upon registration, generate an 8-letter alphanumeric code unique to the user using the formula:- ``- ``- ``- ``- ``**Program Requirements:**- Implement functionality to display all user information, each on a separate line.- Conduct an evaluation trial with at least 10 users. Use pseudo values instead of real personal details.**Program Functions:**Include at least the following functions:- `main()`- `register()`- `generate_code()`- `retrieve()`This structure will ensure efficient registration, individual identification, and information display.

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), Dose number (1 or 2), Date of previous dose, Type of vaccine (e.g. Pfizer, Moderna, Johnson & Johnson etc.), Residential zip code. 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

R program please help
In the main.asm file, you are to create a few arithmetic calculations using the following instructions: mov add sub Then after each expression is calculated, you will print the result using: mov rdi, XXX call print_num call print_lf The value of XXX will depend on which register your final result landed. Do this at least 3 times using only the registers ( rax, rbx, rcx and rdx). For example, if you wanted to print the result of 32 + 5 - 10, you could do something like: mov rax, 32 add rax, 5 sub rax, 10 mov rdi, rax call print_num call print_lf Remember that in order for the print_num subroutine to print your number, you must move the result into rdi.
