16 Decrement Operator in C 🔍 GATE Students, Don’t Miss These Traps | GATE C Programming Series
We always talk about ++i vs i++, but what about --i and i--?
*Decrement operators* are often seen as “easy.” But that’s exactly why GATE traps you with them.
In this video, we *dive deep into the behavior of pre-decrement (`--i`) and post-decrement (`i--`)* in C with:
Real GATE-level examples 🎯
Common mistake patterns 😵
Clear mental models you’ll never forget 🧠

🌱 *Why this matters:*
When you're in an exam hall, what kills your rank is not the hard stuff — it’s *careless errors in concepts you *thought you knew.**
This is one of those topics.

❤️ *This video is for every GATE aspirant who’s ever felt like they're not ‘technical enough’ or smart enough.*
Let me tell you — *you are not the problem.*
You just need the right lens to decode these traps.
If you've ever thought:
“Why does this code behave weirdly?”
“I thought I understood --i and i--?”
“Why do I get different outputs in similar-looking programs?”
Then this video is your fix.
