Question

C++ / C#

Hello! I want to write a program for testing.
You need:
1) So that the application can be installed on several computers.
2) Login form. Fields for administrator and user. The user enters the test, and the admin enters his panel.
3) So that the administrator from the panel can add questions and answer options to them.
4) So that the administrator can enter the program on his computer and check the results.
5) The algorithm for calculating points and for a certain one issued a message with the percentage of points scored and the text passed or failed.
Tell me what is required for this, what steps or algorithm, etc.

Answer 1

1) Local network or remote server, the latter is easier.
2) Database on the server.
3) Interaction with the server, either via HTTP or TCP/IP. And with the MySQL database, in theory, you can interact directly if not hosting or if hosting allows.
Another option, in this case, the algorithm is quite clear and understandable.
1) Get money.
2) Go freelancing.
3) Order this project.
4) Choose an artist.
5) Make an advance payment.
