问题 单项选择题

以下关于程序语言的叙述,正确的是()。

A.Java语言不能用于编写实时控制程序

B.Lisp语言只能用于开发专家系统

C.编译程序可以用汇编语言编写

D.XML主要用于编写操作系统内核

答案

参考答案:C

解析:使用某种高级语言编写出来的程序被称为该语言的源程序。计算机不能直识别用高级语言编写的程序指令,必须将高级语言程序"翻译"成计算机可以直接识别的机器语言程序。然而,用人工进行这样的"翻译"实际上是不可能的。因此,人们在创造高级语言的同时还要编写出用计算机自身将高级语言程序"翻译"成机器语言程序的软件。这样的"翻译"软件叫作高级语言的编译软件(程序)。在编辑和执行高级语言程序的时候都需要有该种语言的编译软件的参与。编译程序可以用汇编语言编写。
