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