ST20-SWC++ Preprocessor

Product Overview

The C++ Preprocessor is derived from

C++ Language System version 3.0.3 of UNIX System Labora-

tories Inc.

SGS-THOMSON Microelectronics has developed its own tools and libraries so that the C++ compiler,

used in conjunction with the ANSI C Toolset, can be used to programme ST20 and transputer targets.

The C++ Preprocessor is available for two development platforms:

ST20-SWC++/PC C++ Preprocessor for IBM PC under MSDOS 5.0

ST20-SWC++/SUN C++ Preprocessor for Sun 4 under SunOS 4.1.3 or Solaris 2.4

1.1

C++

C++ is a general purpose programming language which has evolved from C. It combines the benefits

of object orientated programming with the efficiency of C.

Its benefits include:

Strong Type Checking

Helps reduce coding problems.

Encapsulation

Constructing large applications is easier by using C++ classes. A C++ class is a user defined

type which may contain data to represent the type, and member functions to implement oper-

ations on the type.

Data Abstraction

Ease maintenance and product evolution by restricting access to a class’s implementation

details.

Multiple Inheritance

Classes may inherit properties from other classes. This enables classes (and hence effort)

to be reused.

Dynamic Binding

Use function names consistently, independent of object type, as class members may be

bound dynamically at run-time (virtual functions).

Type-Safe Linkage

Provides function argument checking across different compilation modules. This enables the

correct function to be acquired by a linker when several alternatives are available in the pres-

ence of function overloading.

Parameterized Types (Template)

Allows users to define a type in terms of another, unspecified type, providing a facility for

defining extensive standard libraries.
