String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
CPython is the reference implementation of the Python programming language. Written in C and Python, CPython is the default and most widely used implementation of the Python language. CPython can be defined as both an interpreter and a compiler as it compiles Python code into bytecode before interpreting it.
In C++ it is part of the Standard Library since C++17 and Boost provides the generic Boyer–Moore search implementation under the Algorithm library. In Go (programming language) there is an implementation in search.go. D (programming language) uses a BoyerMooreFinder for predicate based matching within ranges as a part of the Phobos Runtime ...
Cython – programming language to simplify writing C and C++ extension modules for the CPython Python runtime. IronPython – Python for CLI platforms (including .NET and Mono) Jython – Python for Java platforms; MicroPython – Python 3 implementation for microcontroller platforms
For example, implementations of Python include: [9] CPython, the reference implementation of Python; IronPython, an implementation targeting the .NET Framework (written in C#) Jython, an implementation targeting the Java virtual machine; PyPy, an implementation designed for speed (written in RPython)
As a precursor to the lambda functions introduced in C# 3.0, C#2.0 added anonymous delegates. These provide closure-like functionality to C#. [3] Code inside the body of an anonymous delegate has full read/write access to local variables, method parameters, and class members in scope of the delegate, excepting out and ref parameters. For example:-
Calls from one language to another are exactly the same as would be within a single programming language. If a library is written in one CLI language, it can be used in other CLI languages. Moreover, apps that consist only of pure .NET assemblies, can be transferred to any platform that contains an implementation of CLI and run on that platform.
// Compares two strings, up to the first len characters. // Note: this is equivalent to !memcmp(str1, str2, len). function same (str1, str2, len) i:= len-1 // The original algorithm tries to play smart here: it checks for the // last character, then second-last, etc. while str1 [i] == str2 [i] if i == 0 return true i:= i-1 return false function search (needle, haystack) T:= preprocess (needle ...
