For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.
In many programming languages, string concatenation is a binary infix operator, and in some it is written without an operator. This is implemented in different ways: Overloading the plus sign + Example from C#: "Hello, " + "World" has the value "Hello, World". Dedicated operator, such as . in PHP, & in Visual Basic [1] and || in SQL.

C# has a static class syntax (not to be confused with static inner classes in Java), which restricts a class to only contain static methods. C# 3.0 introduces extension methods to allow users to statically add a method to a type (e.g., allowing foo.bar() where bar() can be an imported extension method working on the type of foo).
String concatenation is an associative, but non-commutative operation. The empty string ε serves as the identity element ; for any string s , ε s = s ε = s . Therefore, the set Σ * and the concatenation operation form a monoid , the free monoid generated by Σ.

With 15.5 million U.S. adults currently diagnosed with ADHD, there is a growing focus on warning signs of the disorder. Mental health experts share the most common signs and symptoms.
In computer science, string interning is a method of storing only one copy of each distinct string value, which must be immutable. [1] Interning strings makes some string processing tasks more time-efficient or space-efficient at the cost of requiring more time when the string is created or interned.
