Kas enamikus programmeerimiskeeltes on String viitamis- või väärtustüüp?

In most programming languages, strings (String) are implemented as reference types, not value types.

Specifically, in C# string is a reference type that behaves as an immutable (unchangeable) object. This means:

• A variable of type string contains a reference to an object in memory.
• When the string is modified, a new object is created, and the existing one is not changed.
• Thanks to immutability, strings can be safely used in multithreaded environments and can be cached.

This differs from value types (e.g., int, struct), which are stored directly in the variable and copied upon assignment.

Example:

string a = "hello";
string b = a;
a = "world"; // b still is "hello" because strings are immutable and a now references a new object
