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.
This comparison of programming languages compares how object-oriented programming languages such as C++, Java, Smalltalk, Object Pascal, Perl, Python, and others manipulate data structures. Object construction and destruction
valid declaration statements are of the form Dim declarator_list, where, for the purpose of semantic analysis, to convert the declarator_list to a list of only single declarators: The As clauses of each multiple declarator is distributed over its modified_identifier_list

Note that in order to use Map, you have to provide the functor Map.Make with a module which defines the key type and the comparison function. The third-party library ExtLib provides a polymorphic version of functional maps, called PMap, [12] which is given a comparison function upon creation.

In contrast, the C# System.DateTime is an immutable struct value type for date-and-time information with 100-nanosecond precision; the .NET 6 API also added System.DateOnly and System.TimeOnly, similar structures for date-only or time-only operations. [25] C# additionally defines a System.TimeSpan type for working with time periods; Java 8 ...
