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.
A class or abstract class may implement one or more interfaces. An interface can only extend other interfaces. An abstract class may have non-public methods and properties (also abstract ones). An interface can only have public members. An abstract class may have constants, static methods and static members. An interface cannot.
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
The FBISE was established under the FBISE Act 1975. [2] It is an autonomous body of working under the Ministry of Federal Education and Professional Training. [3] The official website of FBISE was launched on June 7, 2001, and was inaugurated by Mrs. Zobaida Jalal, the Minister for Education [4] The first-ever online result of FBISE was announced on 18 August 2001.

Type tests, e.g., :? string as s; Active patterns, which can be defined over object types [54] F# object type definitions can be class, struct, interface, enum, or delegate type definitions, corresponding to the definition forms found in C#. For example, here is a class with a constructor taking a name and age, and declaring two properties.
The Sun Microsystems Java compiler requires that a source file name must match the only public class inside it, while C# allows multiple public classes in the same file, and puts no restrictions on the file name. C# 2.0 and later allows splitting a class definition into several files by using the partial keyword in the source code. In Java, a ...

NP-hardness of pattern language membership, by reduction from the NP-complete 1-in-3-SAT problem: Given a CNF of m clauses with n variables, a pattern of length 3n+4m+1 with 2n variables and a string of length 4n+5m+1 can be constructed as shown (m=3 and n=4 in the example). Upper-case variables in the pattern correspond to negated variables in ...
