Hey all,

I’m doing something a little different next week.

I’ve been a developer at Programiz for 3 years, mostly working on turning designs into fully functional web pages. I’m not an AI expert — but I’ve been experimenting with how AI fits into real, messy day-to-day dev work.

So on July 23, I’m doing a live session where I’ll build a landing page using AI tools. You’ll see me read, debug, and fix the code as it comes in — no script, no perfect prompts. Just me trying to make it work, like most of us do.

If that sounds like something you’d want to check out:

Hope to see some of you there!

Hello, I’m looking to learn C++, and I’m pretty sure I’ve decided on this service as it’s spoken about positively, and I saw an app and a website so there are options on the go as well as at a desk.

I cannot however figure out how to log into the app. Does it actually not share the info with the online user database? I am ready to pay for a lifetime subscription but it seems really weird to not have the two programs connected. Could anyone shed some light on this?

Thanks so much for all the on the visualizer! 🙌

Happy to announce that it is now stable and out of beta.

 We’ve recently added a bunch of new data structures for you to explore visually:

🌳 : insertions, deletions, and search, fully animated
🧱 : push/pop, frame by frame
🔗 : inserts, deletes, traversals
📦 : visualize FIFO in action

Try them out and let us know what you think in the comments.

Ohh and, BST is our new favorite. 🌀

We're just getting started, and there's more coming soon (👀 Heaps, maybe?).

I want to get the lifetime access to Learn C++ : Programiz app. The lessons have been helpful and I am really interested in learning c++. I wish to know if it is worth getting it.

Can someone explain why having the word "system" all lowercase completely bricks the code? It also does this when you put it into a printf statement, and I assume it would do the same if it shows up at all

Hey i mailed at to redeem a voucher 2 weeks ago and i still have not got an response from them.

Hey ! Sudip from Programiz here. 👋 Wanted to share what we've been up to in 2024!

The TL;DR - We've dedicated our entire effort to making coding less scary for beginners and helping them become confident in their skills.

Some cool stuff we launched:

• Totally redesigned our lesson pages to be way less overwhelming

• Added 2300+ coding challenges (Python, Java, C++, JavaScript, SQL)

• Built a code visualizer that shows exactly how your code runs, step by step

• Upgraded sensAI to give you personalized, actionable insights for improvements

With all these launches, we saw impressive growth - 280k new learners joined us this year and wrote nearly 1M codes! 

Check out our year-end blog to see everything we did this year.

2025's looking even better - we've got AMAs with industry experts, free courses, early feature access, and some other surprises planned just for our Reddit.

Until then, I wish you a Happy New Year and Happy Programming!

Hi Reddit, it's Ashmita from Programiz.

I'm excited to announce that we've just launched our new Code Visualizer, and I can't wait for you guys to try it out.

We created this visualizer for those moments when you realize your code works perfectly fine but have no idea how it's actually working. We believe this will be of great help for those just taking their first steps into programming.

So, here's what you can do with it:
• Watch your code transform into an interactive visual diagram.
• Follow along with clear explanations and visual guide for each line of your code.
• Track how your variables change, loops execute, and logics flow in real-time.

We’ve integrated the visualizer into our Learn Python Basics course. You can try it right now in these lessons:

Try it out and let us know your thoughts on this thread.

Happy Programming! 🙌🏻

I've been working on a homework project, and I found that anytime I use a cin command, I get a puzzling output. Here's a simplified example:

The answer just gets enclosed in quotes and the program doesn't finish executing.

I tried it in a different online compiler and it works as expected.

Please let me know if there's something specific I need to be doing to make cin work in Programiz.

I purchased lifetime Pro subscription on 8th Nov 2024 @ 5999rs on blackfriday sale. After the payment I went to see that did I got the subscription then I saw lifetime Pro status: inactive and ① Action Required: Resubscribe to PRO Lifetime again ?. So I Gmailed support () about this issue 3 times in that 3 times 2 times they said

"Apologies for the inconvenience.

I have escalated the issue to the technical team and they are actively looking into it. I'll keep you posted on any updates I receive towards its resolution.

Thank you for your patience."

after that i replied

"Thank you for your response. Can I know when this issue might be solved?" on 9 Nov 2024, 08:19 IST

i got no reply so i messaged them again

"Hello? How much time it will take to resolve the issue?" on 9 Nov 2024, 16:05 IST

and

"Reply something." on 9 Nov 2024, 16:06 IST

and all the necessary screenshots are in this reddit post.

this is 3th day i am just fed up with soo i am posting this online now .6000rs might sound cheap to you guys but for a student like me it's a lot of money to spend .i contacted programiz many times for suggesting to add some features but i never got this kind of worst support from programiz . i purchased annual subscription once but this issue didn't happened to me and it expired on 24 aug 2024. i hope this issue is solved asap

Sorry for the re-post, but when I saw the "Help" tag, I wanted to make sure I posted this in the right place. Thanks!

I'm trying to pay an additional $79.00 for the upgrade to the lifetime option. However, I get an error. It says "PRO Annual $127.20/ yr Status: Active" and I see the upgrade to lifetime for $79.00. However, when I click it I get the error, "Unable to upgrade to an invalid or ineligible plan." I have the annual plan for $129.00. "Subscribed On 12th May 2024 Next Renewal 20th May 2025 (00:00 UTC)"

I seem to have two plans? But I don’t in actuality. I’m sure I used the 7 day free trial and then paid for the year at $129.00. On my account, it says…

PRO Annual - 7days Free Trial $127.20 18th May 2024 <view>

PRO Annual - 7days Free Trial $0.00 11th May 2024 <view>

So I figured maybe the 7 day free trial at $0.00 being active was the problem and messing up the upgrade to lifetime? So I just cancelled the $0.00 7 Day and it seems to have cancelled both? My intent was to try to get around the “lifetime” error and leave the OTHER “Pro Annual - 7days Free Trial” at $127.20 active. Now the offer to upgrade for $79.00 is gone altogether. AND the account for $127.20 says it will now end on “Subscription cancelled. Your PRO subscription will be inactive after 20th May 2025.” This is VERY confusing.

Now, when I try to click the "view" link for the account for $127.20, I get a new error message, "Page Not Found. Sorry, the page you are looking for could not be found."

I think I just made things worse while trying to figure out why the upgrade was bugging out. I guess these "two" accounts with two different "view" links are really one and the same? Even though one was the trial for $0.00? And the other was for $127.20?

Indeed, very confusing. So now things are worse.

I’m just trying to upgrade my main account listed at $127.20 and ending May 20th 2025 to lifetime upgrade for the extra $79.00. How do I do this?

Maybe the original error is because I need to switch payment options? My original card on file had a fraudulent charge of a whopping $8.00 and my small, local bank had no choice but to close the card and issue a new one? But I was never given the option to select, change, or even choose a payment option before receiving that original error message, "Unable to upgrade to an invalid or ineligible plan."

Please help as I want the lifetime upgrade for $79.00.

Thanks to anyone from Programiz that can help me out. I would greatly appreciate it.

I was using the C++ Playground and started getting this cryptic error.

I backed up the last couple of changes and continued getting it, and even managed to get it running on the but it still won't run in the playground, so I assume this is a website problem, not a code problem?

Does the software limit the number of devices that can access it at the same time? For example, if I am logged into this software and my friend also logs in, will the account be logged out? (We are using the same account). For example, if I have completed the C course but want to review it, can I start learning it again from the beginning?

The expected output and my result looks the same. Is there any difference? Why does it show wrong?

I am one of your subscriber on YouTube. Please I just wanted to make a request only. Can you please do a video-tutorial on C++ like you did on C programming. I really really enjoyed all the C programming tutorials. They are comprehensive and easy to learn. Thank you so much, the tutorials really do helped me get a gasp of C programming.

Again Thank you...!!

so i was making a button in java online in programiz then it showed me ramdom errors

Hello! I've been exploring interactive sites to learn Java and decided to try Programiz. I noticed they have DSA courses for Python and C++, but not for Java. Does anyone know if there's a plan to add a Java DSA course? I love the way Programiz presents lessons and practices, and I'd like to learn everything about Java in one place. Thanks!

Something went wrong with C++ compiler. I receive "/bin/sh: 1: clang++: not found" in interactive window.

I suppose you updated something or installed a new version of clang
