Like in C and C++ there are functions that group reusable code. The main difference is that functions, just like in Java, have to reside inside of a class. A function is therefore called a method. A method has a return value, a name and usually some parameters initialized when it is called with some arguments.
ToList: Creates a List<T> from the collection. ToDictionary: Creates a Dictionary<K, T> from the collection, indexed by the key K. A user supplied projection function extracts a key from each element. ToLookup: Creates a Lookup<K, T> from the collection, indexed by the key K. A user supplied projection function extracts a key from each element.
String functions common to many languages are listed below, including the different names used. The below list of common functions aims to help programmers find the equivalent function in a language. Note, string concatenation and regular expressions are handled in separate pages.
A string is a prefix [1] of a string if there exists a string such that =. A proper prefix of a string is not equal to the string itself; [2] some sources [3] in addition restrict a proper prefix to be non-empty. A prefix can be seen as a special case of a substring.
The array L stores the length of the longest common suffix of the prefixes S[1..i] and T[1..j] which end at position i and j, respectively. The variable z is used to hold the length of the longest common substring found so far. The set ret is used to hold the set of strings which are of length z.
Most of the functions that operate on C strings are declared in the string.h header (cstring in C++), while functions that operate on C wide strings are declared in the wchar.h header (cwchar in C++). These headers also contain declarations of functions used for handling memory buffers; the name is thus something of a misnomer.
In the above example, IIf is a ternary function, but not a ternary operator. As a function, the values of all three portions are evaluated before the function call occurs. This imposed limitations, and in Visual Basic .Net 9.0, released with Visual Studio 2008, an actual conditional operator was introduced, using the If keyword instead of IIf ...
For example, 0x10ULL evaluates to the value 16 as an unsigned long long integer in C++: the 0x prefix indicates hexadecimal, while the suffix ULL indicates unsigned long long. Similarly, prefixes are often used to indicate a raw string , such as r"C:\Windows" in Python, which represents the string with value C:\Windows ; as an escaped string ...
