C. Design a student course selection system. Urgent!!

It's not easy to get it.,Course selection information must be dynamically added or you do it by hiding and showing.,The number is clear to you.,When you add it dynamically,Mark the ID of each checkbox in order.。 Then click on the selection of the course,Iterate through the selection of the checkbox according to the number.。。。 If it's a hidden method to display the course selection information, it's better to do it, first determine whether it's hidden, then judge whether it's selected, and then do the data operation.

It's all about saving and updating data.

The more commonly used is to save in the database, there are a lot of references on the Internet in this regard, you can use the access database, you can also use sqlserver, and then the database data update operation, you need to create a database table, write the corresponding sql operation string and the like, or some ** amount.

There is also the serialization that comes with C. This method is relatively simple, that is, there are not many people who use it, and there is not much information on the Internet, so it may not be easy to find the answer if you encounter some small details. If you're short on time, and then there's no limit to using a database, I personally recommend this.

Here's an example::

Basically, you'll need to design a class to store this data

public class xuankeitempublic string user ;

public string classroom;

public string selectedclass ;

And then it's all about storing that data in a file and updating it.

Dear, although this ** is not long, but it is also a lot, There are fewer controls used, try to do it yourself.

Oh, and learned C++? Then choose Windows programming, the concept of C is written in detail, Windows programming is the use of Windows application programming interface (API), write Windows programs.

Generally use C C++; So since I've learned C++, my suggestion is to choose Windows programming.

Comparatively speaking, c is relatively simple. Windows programming is more low-level oriented, and beginners rarely use these low-level things. But sometimes in order to meet special needs, like Delphi, C have to use the Windows API.

Anyway, it's a matter of time before you learn Windows programming, according to your actual situation.

I've written one of this, it's pretty simple, it's mainly to make up a few functions to operate, using struct arrays.
