Why C Strings End with \0 - Null Terminated Strings Explained Simply

Описание: Ever wondered why C strings are just character arrays that magically know where they end? It's all because of the null terminator - that sneaky \0 at the end.

In this video we break it down super simply:
What a C string actually is (spoiler: just bytes)
Why old-school assembly needed separate length labels
How adding a single zero byte fixed everything
Quick look at ASCII codes for "Hello"
Why \0 is the perfect terminator (and how to write it in code)
How loops know when to stop reading the string
Real example in assembly with and without null termination

Perfect if you're learning C, diving into low-level programming, or just curious about what's really happening when you write "hello" in C.
