Describes the form and establishes the interpretation of programs written in the C programming language.

1. This International Standard specifies the form and establishes the interpretation of programs written in the C programming language.¹⁾ It specifies

   • the representation of C programs;

   • the syntax and constraints of the C language;

   • the semantic rules for interpreting C programs;

   • the representation of input data to be processed by C programs;

   • the representation of output data produced by C programs;

   • the restrictions and limits imposed by a conforming implementation of C.

2. This International Standard does not specify

   • the mechanism by which C programs are transformed for use by a data-processing system;

   • the mechanism by which C programs are invoked for use by a data-processing system;

   • the mechanism by which input data are transformed for use by a C program;

   • the mechanism by which output data are transformed after being produced by a C program;

   • the 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 processor;

   • all minimal requirements of a data-processing system that is capable of supporting a conforming implementation.

3. This International Standard is designed to promote the portability of C programs among a variety of data-processing systems. It is intended for use by implementors and programmers.
