This C++ Vector Bug Catches Everyone 😵 | Can You Spot It?

Описание: This C++ bug looks harmless — just a simple vector and a loop, right? But the output will leave you scratching your head! 🤯

Many developers assume a vector initialized with a size can be filled using push_back — but that adds elements on top of the existing ones. So instead of getting what you expect, you get extra values!

It's a classic case of misunderstanding how vector initialization vs dynamic growth works in C++ STL.

💡 Takeaway: Know when to use reserve, when to use resize, and when push_back might break your logic silently.

Comment below what you expected the output to be before watching!
