4.3 访问和设置记录(Access and Set Records) 使用记录的成员时,只需在记录和其成员之间用 “.” 隔开即可。如赋予My_Card中的变量 Full_Name 值 Jack Werlch: My_Card.Full_Name := "Jack Welch "; 设置记录成员的值和设置数组给人感觉上有点类似,如: My_Card := ("Jack Welch ", 19830519,45, "...
上例的Matrix是二维数组,多维数组的index_specification由多个范围组成,每个范围由 , 隔开。 3.7 访问和设置数组(Access and Set Arrays) 访问数组时,只需在添加在index specification范围内的下标,如 3.2 中的数组Unit1: Unit1 (1) := 190; -- 赋予Unit(1)值 190; Unit1 (7) := 210; Unit1 (7) > ...
保留字在程序语法中有特殊的含义,不属于标识符范围,这与C 和 Pascal 等语言的定义有所不同。Ada 95 中的保留字如下:abort abs abstract accept access aliased all and array at begin body case constant declare delay delta digits do else elsif end entry exception exit for function generic goto if in ...
Ada is a state-of-the art programming language used for critical software: fsmall-footprint, real-time embedded systems to large-scale enterprise systems.
In addition to these aspects, the language covers real-time programming, with facilities to model parallel tasks and to handle exceptions. It also covers systems programming; this requires precise control over the representation of data and access to system-dependent properties. Finally, both ...

Additionally, Ada 2005 expands the predefined library (including generic "container" packages that improve upon C++'s STL) and makes a number of improvements in the access type area. About AdaCoreFounded in 1994, AdaCore is the leading provider of commercial, open-source software solutions for ...
注:其中Access类似指针,Array是(逗号分隔成多维)数组结构,Record是复合结构(可以用来表示任何C/C++的struct或class表示的组合数据),Task/Protected是ADA语言内建多任务并发的任务单元。 图片来源:http://en.wikibooks.org/wiki/Ada_Programming/Type_System
