Question for the dev community! 🤔

​After you successfully complete a feature and it finally works, how long of a break do you usually take before starting the next one?

​Do you keep the momentum going or step away to recharge? ☕👇

@payalpixel Jab tak code hai, tab tak bugs hain... Infinite loop me phanse hue hain hum sab! 🔄😭💻

I’m asking because Day 14 completely fried my brain today! 😅 I just built a custom C++ email validator from scratch and merged my first feature branch.

You can check out what I built here: 👇

Building email validation from scratch without regex is a real puzzle! 🧩

Today for my C++ CRM, I built custom logic to track @ and . offsets, handle spaces, and auto-lowercase inputs.

Best part? Successfully merged my feature branch into main! 🌿➡️🚀

Day 14 behind the scenes! 🔍

Here is the custom C++ logic I wrote to validate emails without using external libraries or regex. Handled edge cases like @ & . positions, space checks, and the erase-remove idiom to strip | delimiters! 👇

@codewithharry Took Git branching out of tutorials and into real code! 💻

Isolated all the file storage work on a separate branch before merging. No more fear of breaking working code on main—game changer for my workflow! 🛑✨

Day 13 of #100DaysOfCode 🚀

My C++ CRM was deleting @ from emails due to over-sanitizing! 🤦‍♂️

Fixed it + added File Persistence today:
💾 Custom |-delimited File I/O
🛠️ stringstream parsing (stol/stod)
🧹 Clean Git history via commit --amend

Data persists! 🔥 #cpp

Spent today mastering Git Branching with @CodeWithHarry! 🌿

Visualizing how feature branches separate experimental code from main was a lightbulb moment. 💡

Essential commands:
🔹 git branch <name>
🔹 git checkout -b <name>

No more breaking production code! 🚀 #Git #cpp

[Mrinal @BuildWithMrinal]

@payalpixel Financial freedom & building your own identity hits different! 💯

Keep going! 🚀

[Mrinal @BuildWithMrinal]

Here's a look at the actual File I/O implementation! 🛠️

Using stringstream with | delimiters to parse strings back into types with stol() / stod(), and saving new records with ios::app mode. Simple and effective persistence! 💻

@simpleCheena You are absolutely right.

Breaking the problem down to 'make it pass, then sleep' is exactly the strategy I need tonight. Thanks for the motivation! 🚀

[Mrinal @BuildWithMrinal]

My sleep schedule is officially ruined. 📉

​I’m so obsessed with completing my C++ CLI CRM project that my brain is literally writing code while I try to sleep. 🧠💻

​Is it just me, or do you guys also lose sleep over finishing a project? 👇

In case you are wondering what exactly kept me awake... 😂

I just wrapped up the core 'Add Contact' logic with bulletproof input validation for Day 12.

Check out the full technical breakdown and code here: 👇

Day 12 of #100DaysOfCode 🚀

Added crash-proof input validation to my C++ CLI CRM! 🛠️

✅ Exact 10-digit phone check
✅ cin.clear() stream recovery
✅ 3-attempt retry failsafe
✅ Zero garbage data (Struct defaults)

What’s your go-to trick for CLI input validation? 👇

@AnushkaGupta_11 I think it depends on your career path.

If you want to go into frontend development, having a solid understanding of basic CSS is definitely useful.

But if you're mainly focused on backend development, not knowing CSS isn't really a problem.

Choose what aligns with your goals.

[Mrinal @BuildWithMrinal]

@AnushkaGupta_11 I have a question!
Are you follow any DSA Sheet?

[Mrinal @BuildWithMrinal]

For the curious devs, here’s the C++ code behind the validation! 💻👇

📸 1: readID() using cin.clear() to flush streams & a 3-retry limit.
📸 2: readPhoneNum() enforcing the strict 10-digit rule.
📸 3: isAllDigit() using ASCII logic for lightweight checking.
