I need to check the response coderesponse_code I get from a device with the checksum method. In the description of the response codedesc_of_response, it says control characters are included, but control characters are not in the format that I can checksum. I'm not experienced in this, I'm just starting to learn. I would be very grateful if someone could help me.
How should I do the checksum process? Do I have to take the whole message into account when doing it? How should I deal with non-hexadecimal characters?

Im trying to filter some type of data into 3, full history, sent, and received. Im using a useState hook, already using the set, but dont know where to use the first variable. And its printing me all the transactions.
im doing a statement verifying if the transaction inside the array is none(history, received(credit), or sent(debit, and placing that into an empty array.
And here im trying to use the variable and the hook with a component that i created.
idk if i have to put something different in the 'data' prop.
Thanks in advance :)

I am new at programming and was wondering if you could give me some advice as to how to make a alphanumeric character press do something using C? I would like to program a different function for each character pressed. Can anyone help me?
In your window procedure, you can react to WM_KEYDOWN messages. Your window will receive such a message when the user starts pressing down a key. When the user lets go of the key, you will receive a WM_KEYUP message.
See this tutorial on window messages for the basics on how to handle window messages.

For instance a single string matching is the z-algorithm. It's the fastest matcher.

I am trying to create a C program which will create a wordsearch and then give the user a time to complete it in and then the program will output a message accordingly. My problem is that I cannot figure out how to ask the user for input while counting down. Any help is appreciated.
Make the user input method it's own thread, a child of the main thread. Use wait in the main thread and then end the child thread when the wait is over. Let us know if you have questions on how to create threads or how to use mutex to keep data secure.

How do i edit an XML nodes property?
I have tried using xmlNewProp, however, that does not overwrite the property. It just adds a new one.
So I was wondering if there is a way to either remove that property, or edit the propery.
Edit:
I understand that some people did not quite get what I was trying to do. Well, the thing was that I needed a way in C using libxml2 to update a nodes properties. I tried using xmlNewProp, however that did not work.
Someone suggested xmlSetProp, and that worked fine. My problem were that the documentation for lxml were huge, and it was difficult to locate the needed functions.
Based on libxml documentation, you can use xmlSetProp to set an attribute from a node.
