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.
Though primarily an imperative language, C# always adds functional features over time, [100] [101] for example: Functions as first-class citizen – C# 1.0 delegates [102] Higher-order functions – C# 1.0 together with delegates; Anonymous functions – C# 2 anonymous delegates and C# 3 lambdas expressions [103]
