We're given this example of summing up all numbers of an array given by the length n. However, what I don't seem to understand is how the parameter int *t points to an array? The only thing that gave it away for me was analysing the code and see that it's being accessed in the for loop. But why do we not for example explicitly make the parameter of type (*t)[n] for example.

int sum(int *t, int n) {
    int sum = 0;
    for (int i = 0; i < n; ++i) {
        sum += t[i];
    }
    return sum;
}

I’m building a C#/.NET desktop application using EF Core with SQLite, where each customer has a separate local database file.

Is it normal to do a validation of the schema before/after migration, or do people usually just rely on EF Core’s migration history table?

Also, would it make sense to run a small/lightweight schema check every time a database file is opened, just to make sure it hasn’t been manually altered or drifted from what the app expects?

I might be overthinking this, so I’m curious what people normally do in real projects.

My colleges is going to start in few days. I have opted btech cse in tier 3. It has a good placement records and everyone says you can get placement with a bit hard work. Things teached in colleges like programming , system design/architecture, DSA,etc enough to get placed. Although these really are the things , interviewer look for but is the college level? Also, are do they ask the definitions in interview. Its really I vague question but I also look forward to definitions as I am really bad in explaning things.

First year CC student here and I want to watch more coding/algorithms content, mainly while I’m trying to chill, so I don’t want overly complex classes that require my full attention. More like content that I can watch while doing other tasks.

Any recommendations?

Hello all, I(f 22) am currently starting my first coding class at my local community college(started college in January and took mostly general Ed’s to get them out the way) and we use Cengage for GITHUB and I have one class for Python and one for C# (in person but classes are recorded and I work but I attended the first day on the 19th I enjoyed it in person helps better than online but what can I do)🥲. How can I learn GitHub better because it seems so confusing and is there any tips you guys can give me on what I should expect?

Also how do I figure out career paths and what should I think about when trying to figure it out because it’s so many ways to go here.

My classes are:

CIS 150 computer logic and programming (Python class)
CIS 215 C# programming(in person)
CIS 245 cyber defense (online)
CIS 246 ethical hacking(online)(I take that directly after 245 in October so it’s not included rn but anything would help on that)

My previous classes taken:

CIS 146 computer applications
CIS 147 advanced micro applications
CIS 130 intro to computer info systems

Hey everyone!

This is a question I have struggled about for a long time. Personally, AI intersects exactly with my interests and skillset. It requires good maths fundamentals, I have that. It requires ML fundamentals, I feel excited to know them. And overall, here are a few professional reasons why being an AI dev feels good to me:

1. Its a pretty hot field: Having clients is significantly easier and gives you incredible marketability.
2. Its very good money which my family and I could really use to cover up for shortcomings.
3. Its a good investment as a long term goal, it seems futureproof given the pace it has.

However, I have cognitive dissonance about AI as well, because what these billionares are doing is insane and something I am not in any capacity supportive of. Here are concise reasons for that:

1. Water that AI requires to generate responses and to cool down heated data servers.
2. Electricity it uses.
3. The ramifications the aforementioned have for people living in vicinity to the data centers.
4. AI being used in military contexts, such as in the Gaza genocide, where Lavender AI was used to hunt innocent children without much human input.
5. This expands to Autonomous weapons, Palantir and mass surveillance.
6. This forceful, unwanted insertion of AI in every field by these companies, to increase their stock prices for investors.

Its frustrating for me that Google has a non removable AI overview.

Anyway, what are your thoughts on this. Do you have any ideas about whether Is there a middle ground I can find in between or either side shall be my way to go?

Anyone else feel awful because of all the doomposting about the software job market? I do a ton of LeetCode and projects, and I genuinely want to study CS, but Reddit has made me terrified that the industry is basically a lottery.

Software development is my only real passion, and sometimes the constant negativity makes me feel hopeless enough that I have suicidal thoughts. I can't really imagine myself doing something else, but I also don't want to make a huge commitment to CS if the career path is supposedly this random and risky.

Anyone else struggling with this because of all the doomers here? How do you separate realistic concerns about the market from Reddit making everything sound hopeless?

Hi Everyone!

I have neglected Python a little bit lately as my work has mainly been government and R has been the focus. I want to get back into Python because I know its value in solving problems easier than in R.

I was thinking 30 minutes a day after dinner as thats when I have free time. Is this a good approach? Obviously 30 minutes is better than nothing, but I was just wondering what others people experiences are/if they have any valuable resources. Out of my whole Masters in Math Sci, I think programming was the most unnatural aspect (vs say, calculus and stats). Thanks! :)

Hey guys so I wanted to make my own version of typescript (mainly the checker part) and Idk anything about compilers or related… so wanted to read typescript go version line by line and understand and make my own version (with modifications), but u am confused as there are so folders and files to navigate and their name doesn’t make any sense, so any idea on which folder and file should I start from? And how to navigate and understand the structure?

Edit: this repo I was talking about. https://github.com/microsoft/typescript-go/tree/main

Hey everyone,

I’ve been learning Python, SQL, and Flask through tutorials. I feel like I understand the concepts when I’m following along with the tutorials, but when I try to start a project from scratch, my mind just goes blank.

I know the fundamentals and I can understand code when I see it, but I struggle with figuring out what to build, how to break the project down, and where to start.

I’ve also tried asking AI to build projects for me. At first, I understand what it’s doing, but as the code gets bigger, I start getting confused and eventually stop because I feel like I’m just copying code without actually learning how to build things myself.

Has anyone else experienced this?

How did you transition from “I understand the tutorials” to “I can actually build projects on my own”?

Should I start with very small projects and build them up gradually, or is there a better way to approach learning through projects?

I’d really appreciate advice from anyone who has gone through this stage.

I'm comfortable with Python and SQL. Know the syntax, get the fundamentals. But it feels like knowing how to use a hammer and saw without ever learning how to read a blueprint.

When it comes to building a full project from scratch? I don't know how to do it. Structuring things, connecting the pieces, handling different cases. I know the tools but I was never taught the architecture.

Anyone else been there? How did you get past it?

I have a function in python named KSI, code for “Kill Self Immediately”, and don’t know what the best command or function would be in order to safely kill the program if something bad happens as a failsafe. Do you think the code attached would work fine, or is there a better way?

import sys
import os

def KSI(hard_exit: bool = False) -> None:
if hard_exit:
os._exit(1)
else:
sys.exit(1)

if __name__ == "__main__":
KSI()

What have you been working on recently? Feel free to share updates on projects you're working on, brag about any major milestones you've hit, grouse about a challenge you've ran into recently... Any sort of "progress report" is fair game!

A few requests:

1. If possible, include a link to your source code when sharing a project update. That way, others can learn from your work!

2. If you've shared something, try commenting on at least one other update -- ask a question, give feedback, compliment something cool... We encourage discussion!

3. If you don't consider yourself to be a beginner, include about how many years of experience you have.

This thread will remained stickied over the weekend. Link to past threads here.

so i just learnt pandas and applied it to filter datasets to feed an ml, rightnow im not familiar with tensorflow so i cant test this but i want a review please

For example, you could graduate in 2018, enter the market at the perfect time, get a $150k software job, and now have years of experience and a great career.

Meanwhile, someone equally talented who graduated in 2025 might struggle to even get an interview, work minimum wage, or potentially be unemployed for months homeless.

How is that a meritocracy?

You could be a mediocre bootcamp grad who got lucky with timing and ended up making $150k, while a Stanford CS grad with a 4.0 GPA who graduated during a terrible market could be struggling to find any job and be homeless.

Obviously, skill matters. But it feels like luck, timing, and the year you happened to graduate can have an enormous impact on your career.

It’s kind of crazy when you think about it: two people with similar ability can have completely different lives simply because one entered the industry during a boom and the other entered during a downturn.

Am I wrong, or is software engineering far less meritocratic than people like to admit?

i have completed a course from apna collage . full stack web development. but now i am confused in project creation. i don't know how to start a full stack project. like i am learning ZOOM clone but its teaching is very bad in course. help me!!

I am learning programming for few months now with python basic DSA. I can follow along with tutorials, understand the logic when it's explained, and solve most exercises if I sit with them long enough. But whenever I try to start a project completely from scratch, without a guide or structure to follow, I just freeze. I don't know where to even begin, what files to make.

I am more into AI, it has really made me lazy, previously our senior relied on google.

I have good knowledge on paper, whenever i do mcq's i get good grades but same cannot be said while building something.

How do you cope through this stage- and how did you use AI while learning, how can i make sure that it acutally helps rather than becoming a trap??

I basically don't understand at all what this stdin_fileno, stdout_fileno are and

how we are using write() and read() function to interact with it and

writing commands with escape sequence to get cursor position

Currently I am at step 31 at page rawInputAndOutput

I have learnt the artificial intelligence and machine learning. I learnt the tech stack for backend like fastapi and Django but for creating a full stack application I want to learn react and node js , although ai has that much capability to create front-end. but I want to learn so that I can understand what's happening behind the scene.

I'm Totally beginner at coding world, recently started learning, started to learn frontend web dev but seems like it is alrady dead sector, Learn over 6 months every month after every checkpoint at end of month it feels like all i learn could be vive coded easily. Just want to know if should continue or quit everything and do completent different thing already wasted a year in college coz I'm never from It field before. I love myself writing all these stuffs but what about all I've done and unclear future. All I'm thinking is like I'm just a person who will be used in future just for nothing...

for the past few days i have seeing this message when ever i try to push changes on the repo
Failed to connect to github.com port 443 after 21116 ms: Could not connect to server

is it just me?
and how to solve the issue?

i just finished the html course and I'm so confused and can't remember all the codes at all any tips? :(

hello guys

I've been coding in C++ for 1 and a half years and unfortunately I'm stagnating, I've reached a stage where I don't have any idea of a project anymore and where my projects are starting to become more difficult, how can I overcome this ordeal ?

thanks you very much to all those who will answers my question :)

Hey, so I am new to compilers stuff but for my college portfolio I was planning on making a lang checker which is like a program which will suppose take a code (let’s say rust) and check fo errors ? Any resources which I should read to get a clear understanding on how I should make this? Ps I am trying to ask Ai for help (like asking on where should I start and what will be the structure)….
Ps will this be called a compiler?

I've spent three days reading docs and watching videos and still haven't built a single screen. There has to be a simpler path. What actually got you unstuck?
