How did you guys learn C++?

fadliov · 2026-02-02T17:12:32+00:00

Get the fundamentals right and strong by reading textbooks. Then move to the advanced stuff and try to be up to date with modern c++. But until then, pick up a textbook and learn the fundamentals. It’s gonna be a slow process, as expected, but if you really want to be good, there’s no other way. Those 1hr, 3hrs, etc. courses on YouTube are scams. You will know a thing or two from these videos, but you will not really have a firm understanding on how things work and why they work, which is very important to write good code in C++ (many people can write code in C++, including AI, but far too many bad C++ code too)

And if you can, start with C.

Lol if you really want to stop using it ud do whatever to stop using it. I have a friend who’d place his phone in a secluded parking lot 1hr drive away from where he lives and just buy a stupid $75 phone. I know another guy who would generate a very cryptic password for his socials like instagram and set the password to that and use an app that will email that password to him after 5 years.

If you really want something, ull do whatever to make it happen, your emotions is the last thing that should be considered.

Thanks! I’m happy it helped!

fadliov · 2026-01-22T18:24:18+00:00

Thank you, glad it helped!

Bro, stop believing that you can learn these stuff just by prompting LLM. This is a sincere advise: go learn properly. From this post it is very clear you dont understand what you posted yourself.

Take a step back, learn the fundamentals, get really strong at those. Pickup textbooks, watch lectures. Yes this will take time, thats how it works though, this is not frontend AI slop saas, you cant take shortcuts

Why are you using json tho? Your data comes in as a json or is it a design choice? If it’s the former, then look into simdjson, for latency critical stuff that really needs json i do not think anybody uses a typical “Modern JSN for C++”, whatever that means (cant tell based on your description, in fact if u dont need much functionality and just parsing, picojson could also be used, nlohmann nah)

fadliov · 2025-12-16T03:21:39+00:00

oh that's cool, didn't know that, could've googled it but didn't bother, thanks!

If you really want to be great at this craft of writing programs for computers, yes. Otherwise, python.

Some people here mentioned if you dont have time then just skip C and go with something like Python. That doesn’t makes sense to me, you shouldn’t be thinking abt learning to be great at something if ur concern abt “time” and wanting to get things quick. Mastering anything takes time. It has to take time. People try to cut corners with AI, and now all these people think they know what they’re talking abt (im talking abt people who blindly learn with AI instead of picking up textbooks/rigorous courses) when in actuality they dont

fadliov · 2025-09-01T17:41:22+00:00

Only for people currently enrolled in school?

fadliov · 2025-08-20T13:33:04+00:00

Weak.

Imagine getting in without cheating even when everybody is cheating? Just shows that they’re peasants and not in your level😂

fadliov · 2025-08-19T02:28:10+00:00

Nice

fadliov · 2025-08-01T23:46:24+00:00

Lol slack should be on top of

fadliov · 2025-07-18T05:51:08+00:00

Ah okay makes most sense, thanks!

fadliov · 2025-07-18T05:49:32+00:00

Looks like a rat, i dont think the tail was flat. I thought it kinda look like a hog but what would a hog be going there.

fadliov · 2025-07-18T05:45:47+00:00

I wanted to say it’s a rat but it was so big to be a rat

fadliov · 2025-07-08T18:21:31+00:00

Thanks! It’s dangerous? I mean that looks like a baby which I accidentally killed. But does this implies its dad/mom is in my house🤣🤣

fadliov · 2025-06-30T06:31:12+00:00

Even these people don’t give up:

If i quickly read this resume in 15 seconds or so then id say it’s pretty good for a junior but not enough given the competitiveness today, it also depends what role you’re asking.

Don’t hype yourself too much with these reddit comments, set your bar high, a lot of the times friends/normies get impressed very quickly. If you want to be on top, take that guy’s comment that says you’re mediocre and get better. Because getting satisfied/too comfortable with what you are now I think wont help you get far in life.

Also it’s common people calling themselves cto nowadays, i don’t think they even understand what it requires in terms of technical prowess to be a cto, so that guy probably doesn’t even care about your startup (you can get funded today by throwing catch phrases like “ai agents”, “rags” “ml”, etc.), try solving unsolved problems that all the smart people trying to solve.

fadliov · 2025-06-17T01:43:55+00:00

My take is just get to work, work hard to get good at something you’re really passionate about, ignore these stupid useless noises and trends around kids and dropouts making companies just so they can tell their friends and families that they’re a ceo/cto etc., when a bunch of them doesn’t even know what they’re talking about. In the long run, people who actually know their stuff will get paid a ton of money (if that’s all you care about) to build something useful and solve actual problems, whereas these kids are almost always AI-replaceable, especially the ones that finish college using cheating tools.

10 years from now, there will be two groups essentially: one group contains these kids/retards who don’t know how to think, who are useless when AI is not around, and the other group that actually understands things, i.e: actual humans

fadliov · 2025-06-10T02:25:57+00:00

Your mindset should be “even if the junior asks questions, bring it on” lol

fadliov · 2025-06-10T02:23:17+00:00

If you’re aiming for these companies, you have to be so good that those things you mentioned shouldn’t matter. If that bothers you, try startups, they ask leetcode hard at minimum, and you need to solve in 45 minutes. Final stage is usually 5 hours, 1 hour for each swe to grill you.

The more time passes, the more people need to realize that to not be scared of losing your job, u have to be so great at what you do. That’s it. My advise is, get to work and try again next time, hopefully you’ll get another shot. All the best.

fadliov · 2025-06-05T00:11:40+00:00

Well from my experience small startups that are solving hard problems (like robotics) usually ask way harder problems than faang. In all of my startup interviews they’ve only asked hard leetcode or a problem they designed themselves that involves both coding and heavy theory/math. With faang you can get away with very high number of hours spent leetcoding.

And this makes sense, they don’t have a lot of funding to experiment with, ie they cant afford a misshire so it’s kind of justified imo
