Скачать или смотреть I built std::vector in C from scratch (No STL, No Magic)

In this video, we build std::vector from scratch in C, without using the STL or any library abstractions.

The goal is to understand how dynamic arrays actually work under the hood — memory allocation, resizing, capacity management, and performance tradeoffs.

We implement a vector-like data structure step by step, covering:

Size vs capacity

Dynamic memory allocation (malloc / realloc)

push_back, pop_back

Insert and erase operations

Growth strategy and amortized complexity

STL-accurate behavior (no automatic shrinking)

This video focuses on mechanics, not syntax.
If you want a deep, low-level understanding of data structures, this series is for you.
