VACCINE REGISTRATION PROGRAM

This project is a program that will streamline vaccination processes by keeping users' vaccination records. In the program, each of the operations is written as a separate function. It is then called and used at relevant places within the program.

The program works by making selections that guide the user on the terminal. A suitable menu has been created to perform the desired operations and the processes continue until exit.

Constraints

• A file named "database.txt" has been created in the project folder and when the program is opened, it reads from this file. If there is a user registered in the file, it reads this user. If the file is empty it does nothing.
• Any update made to the program also changes the file.
• Each record is kept sequentially on a single line in the file. It is recorded using one space between each information. (Ex: AB24 Ali Yılmaz 35 Ankara 01.06.2020 1 X)
• There are 2 different vaccines, X and Y. Users will be able to receive only one of these vaccines. Therefore, both X and Y vaccines cannot be vaccinated.
• Users will be able to receive a maximum of 2 vaccines in total. Requests for new vaccinations from users who have had 2 vaccinations will be rejected.
• People under the age of 18 will not be able to request vaccination.
• At least 1 month must have passed since the last vaccination.

The user must be able to perform the following operations through the program:

• Registering to the system. When the user registers to the system, the following information will be received:

  • ID (4-digit code/must be unique to each user): The ID format is HHRR (H: Letter R: Number) and it should be checked whether the entry is in the correct format.
  • Name
  • Surname
  • Age
  • City

• During the new registration, in addition to the above information, the information provided below will be created with default values. This information will later be used in vaccination registration.

  • Last vaccination date: 01.06.2020
  • Vaccine dose number: 0
  • Vaccine name: NULL

• Viewing the record from the system. All the user's information will be displayed.

• Updating the record in the system. Any information provided by the user when registering to the system (except vaccination information) can be updated.

• Registering for a new vaccination. The system includes two different vaccines. These are vaccines X and Y.

  • The user should be presented with these two options
  • You should be asked to choose one of the options
  • The suitability of the selection made should be checked
  • If appropriate, a vaccination record should be created
  • If it is not suitable, the user must be informed and the selection must be made again.
