本国际标准规定了用C编程语言编写的程序的形式，并对其进行了解释。它规定:C程序的表示C语言的语法和约束解释C程序的语义规则C程序处理的输入数据的表示C程序产生的输出数据的表示C程序的一致性实现施加的限制和限制本国际标准未规定C程序被转换以供数据源使用- 处理 系统调用C程序以供数据处理系统使用的机制 系统转换输入数据以供C程序使用的机制输出数据在C程序生成后进行转换的机制 程序一个程序及其数据的大小或复杂性将超过任何程序的容量 特定数据处理系统或特定处理器的容量能够支持 一致性实施。

This International Standard specifies the form and establishes the interpretation of programs written in the C programming language. It specifies:the representation of C programsthe syntax and constraints of the C languagethe semantic rules for interpreting C programsthe representation of input data to be processed by C programsthe representation of output data produced by C programsthe restrictions and limits imposed by a conforming implementation of CThis International Standard does not specifythe mechanism by which C programs are transformed for use by a data-processing systemthe mechanism by which C programs are invoked for use by a data-processing systemthe mechanism by which input data are transformed for use by a C programthe mechanism by which output data are transformed after being produced by a C programthe size or complexity of a program and its data that will exceed the capacity of any specific data-processing system or the capacity of a particular processorall minimal requirements of a data-processing system that is capable of supporting a conforming implementation.
