Abstract

In a language that allows the programmer to define new types, two characteristics of a formatted I/O system are desirable - it should be extensible and type-secure. We make a demand of a language when we require that such a formatted I/O system be expressible entirely within it.

In this paper we demonstrate that C++ is expressive enough to meet this demand. An extension to the C++ stream I/O library is described that provides formatting capabilities in the style of the c stdio library. An example of its use is:

cout["log of %d is %7f"] << x << log(x)

An object-oriented implementation of this extension is described. The language features of C++ that make this implementation possible are identified to encourage the use of this approach with other languages.
