Mutable & Immutable

• Mutable & Immutable
System.StringBuilder is mutable where variety of operations can be performed
System.String is immutable variable value may change BUT original data value will be discarded and new value will be in memory.




immutable means data value may not be changed but mutable means data value will be changed.

Mutable strings can be modified after they've been created, immutable strings cannot.
