Deca Vs Tren: The Ultimate Showdown Updated For 2025
Short answer:
About 9‑10 kB of storage (≈ 9600 bytes).
---
Why?
The string contains only ASCII/UTF‑8 characters (`a`–`z`, `
`).
In UTF‑8 or plain ASCII each character occupies 1 byte.
Component Length (chars) Bytes
Letters 100 100
Newlines 99 99
Total 199 199 bytes
However, the string is not just a raw sequence of characters.
In many programming languages it is represented as an object that stores:
Length/Size field – tells how many bytes are in the buffer (e.g., 4 or 8 bytes).
Reference count / metadata – for garbage collection or reference counting.
Possible alignment padding – to keep data aligned on natural boundaries.
Typical implementations add a few dozen bytes of overhead:
Length field: ~4 bytes
Reference counter: ~4 bytes
Alignment padding: up to 8 bytes
So the overall memory consumption becomes roughly
`raw_bytes (≈ 400) + overhead (~60–80) ≈ 460–480 bytes`.
In short: The actual number of bytes stored in a string variable is close to the raw character count, but most programming environments add additional metadata and alignment padding. That’s why an `N`‑character string often occupies more than just `N` bytes of memory.
