It depends. Do you want to have autocomplete on the shell the program runs in, or do you want the program to intercept the TAB key and do the autocomplete by itself? Shell autocomplete If you'r...
Storage class specifiers static is strictly speaking a storage class specifier, which is an attribute given to a variable or a function stating how it is allocated, how it is accessible and how lo...
This is absolutely undefined behavior. The C standard doesn't say anything about stacks or how they should behave or how local variables should be allocated on them. The word "stack" doesn't even ...
Some of you may know me from Stack Overflow or the broader network. In light of recent actions by the company, I finally decided to move over to Codidact. I am a subject matter expert on Google App...
When I have tried to read technical explanations of the syntax rules for programming languages, and when I am trying to decipher error messages, I often encounter the terms expression and statement...
I just submitted a proposal to DuckDuckGo here for a new "bang" for their search syntax. If approved: !coddsw search_term will trigger the following URL: https://software.codidact.com/posts/sear...
Linux questions in general are not really topic here. But Bash is. After all, Bash IS a scripting language as much as Javascript. I have a hard time thinking of a question about Bash that is not o...
Let's say I have a script that needs the user to set X number of variables at the start. One can either Pass the arguments in on the command line. Start the program and then have the user input...
sheets tag sounds a little bit too generic and I feel that it should be replaced with the more specific [google-sheets]. I know that we should avoid using company names as much as possible, but in ...
When I first learned about salting, I thought the same thing. But as I understand it, because each salt is unique (or substantially unique within a given database table), storing the salt & has...
Lets say I have two tables, A and B and I need to join a subset of them. Is there best practices of sticking the conditions in the WHERE clause like this, SELECT * FROM A JOIN B on a.fk_b = b....
When reading questions about C programming from beginners, I very often see them describing peculiar run-time errors and crashes, segmentation faults and similar. They have spent a lot of time chas...
Sometimes when I ask questions here, I get told that I should include a minimal, reproducible example. What is that?
Just my two cents: I found this community because of someone's username on Stack Overflow. That's probably a good start. However I then typed 'codidact' into Google. The first result was codid...
I spend a lot of time writing CLI tools in Python, and I would like to support tab-completion in a style similar to Git. For example, subcommands should be tab-completable, options should expand ba...
I recently told a friend that malloc(n) allocates and returns a pointer to a block of at least N bytes of memory, as opposed to exactly N; that it is allowed to allocate 'extra' memory to meet e.g....
Generally speaking, pointer arithmetic is undefined behavior unless carried out on arrays. This is how the additive operators behave, C17 6.5.6: For the purposes of these operators, a pointer to...
When writing any form of custom function such as this: void func (int* a, int* b) Should I add code to check if a and b are null pointers or not? if(a == NULL) /* error handling */ When po...
TL;DR A MRE (minimal reproducible example) is simply the minimal code and information needed for someone who is reading your question to reproduce the problem you are having. It needs to be enoug...
C does have references, but it does not have pass by reference. A reference is simply an expression that references an object (object here is meant in the general sense, not in the OO sense; for e...
Tldr; I don't need to parse HTML, but I need to check if user submitted input conforms to a very strict subset of HTML. Can regex be a suitable tool for this? Details I have a frontend sanitiser th...
I assume "help my code isn't working"/troubleshooting posts - which make up much of SO questions - are allowed. However from reading the FAQ, it's not obvious to me that they are. The "on topic" bu...
Yes Questions about troubleshooting your non-working code are on-topic, provided that you include enough information for the community to understand the context (SO names this minimal reproducible...
I'm working on an API to respond some data about a bunch of orders and items. The order and item numbers are always an integer (it's the order.id and item.id value, respectively). Originally the re...
Generally speaking, if two groups of people collaborate on the same software, I'd recommend they put everything in a shared git repository: Documentation is intimately tied to the version of the ...
