计算机英语》刘艺_王春生_第三版第3单元
第三单元:计算机语言与编程课文A:编程语言一、引言在计算机科学中,编程语言是用于编写可由计算机运行的一系列指令(计算机程序)的人工语言。
与英语等自然语言相类似,编程语言有词汇、语法和句法。
然而,自然语言不适合为计算机编程,因为它们会引起歧义,也就是说它们的词汇和语法结构可能被用多种方式进行解释。
用于计算机编程的语言必须有简单的逻辑结构,它们的语法、拼写和标点符号规则必须精确。
编程语言在复杂性和通用程度上差异很大。
一些编程语言是为了处理特定类型的计算问题或为了用于特定型号的计算机系统而编写的。
例如,FORTRAN和COBOL等编程语言是为解决某些普遍的编程问题类型而编写的——FORTRAN是为了科学领域的应用,而COBOL是为了商业领域的应用。
尽管这些语言旨在处理特定类型的计算机问题,但它们具有很高的可移植性,也就是说它?103f强梢杂美次 嘀掷嘈偷募扑慊 喑獭F渌 挠镅裕 缁 饔镅裕 俏?一种特定型号的计算机系统,甚至是一台特定的计算机,在某些研究领域使用而编写的。
最常用的编程语言具有很高的可移植性,可以用于有效地解决不同类型的计算问题。
像C、PASCAL和BASIC这样的语言就属于这一范畴。
二、语言类型编程语言可分为低级语言和高级语言。
低级编程语言或机器语言,是编程语言中最基础的类型,可以被计算机直接理解。
机器语言视计算机制造商与型号不同而有所区别。
高级语言是必须首先翻译成机器语言计算机才能理解和处理的编程语言。
C、C++、PASCAL和FORTRAN都是高级语言的例子。
汇编语言是中级语言,非常接近于机器语言,没有其他高级语言所表现出的语言复杂程度,但仍然得翻译成机器语言。
1、机器语言在机器语言中,指令被写成计算机能够直接理解的1和0(称作位)序列。
一条机器语言指令一般告诉计算机4件事:(1)到计算机主存(随机存储器)的什么位置去找一两个数字或简单的数据片;(2)要执行的简单操作,如将两个数字相加;(3)在主存的什么位置存放该简单操作的结果;(4)到什么位置去找下一条要执行的指令。
