Sample text

Structs are particularly useful for small data structures that have value semantics. Complex numbers, points in a coordinate system, or key-value pairs in a dictionary are all good examples of structs. The use of structs rather than classes for small data structures can make a large difference in the number of memory allocations an application performs. For example, the following program creates and initializes an array of 100 points. With Point implemented as a class, 101 separate objects are instantiated—one for the array and one each for the 100 elements.

3 Syntactic grammar The syntactic grammar of C# is presented in the chapters and appendices that follow this chapter. The terminal symbols of the syntactic grammar are the tokens defined by the lexical grammar, and the syntactic grammar specifies how tokens are combined to form C# programs. 1). 3 Lexical analysis The input production defines the lexical structure of a C# source file. Each source file in a C# program must conform to this lexical grammar production. input: input-sectionopt input-section: input-section-part input-section input-section-part 34 Copyright  Microsoft Corporation 1999-2007.
