C Sharp (C#) - Strings and StringBuilder

Why does StringBuilder provide better performance than string concatenation in loops?

ABecause StringBuilder modifies the same buffer without creating new strings

BBecause StringBuilder uses multithreading internally

CBecause string concatenation is optimized by the compiler

DBecause StringBuilder stores strings in a database

Step-by-Step Solution

Solution:

Step 1: Understand string immutability
Strings are immutable; concatenation creates new strings each time, causing overhead.
Step 2: Understand StringBuilder internal behavior
StringBuilder uses a mutable buffer, modifying it in place without creating new objects, improving speed.
Final Answer:
Because StringBuilder modifies the same buffer without creating new strings -> Option A
Quick Check:
Mutable buffer = better performance [OK]

Quick Trick: StringBuilder avoids new string creation on each change [OK]
