In our programming learning, we frequently use the i++ or ++i, i-- or --i.
Sometimes, it is pretty tricky to understand why we use them and how they actually work in different perspective.
However, I have discussed everything in a video.
📹 Make sure to watch it to understand better.
Let me also clarify what we call those 4 specific things:
- i++: Post increment
- ++i: Pre increment
- i--: Post decrement
- --i: Pre decrement

Typo :) "--i: pre-increment" should probably say pre decrement.
It's interesting to note that some popular languages do not support these operators for safety reasons, notably: Python & Rust.
Personally I try to avoid these operators unless I need the result of the expression and it's an idiomatic form eg in C:
*p++ = val;particularly in the third term of a for loop, where I preferval += 1which is more portable.Thank you so much for the correction. I did a mistake there for having a rush! Silly me 😅
That's also true, but we tend to use that in Java, C/C++ a lot to be honest.
