2-6-6-4

In the Whyte notation for the classification of steam locomotive wheel arrangement, a 2-6-6-4 is a locomotive with a two-wheel leading truck, two sets of six driving wheels, and a four-wheel trailing truck. All 2-6-6-4s have been articulated locomotives, of the Mallet or related simple articulated type.

Other equivalent classifications are:

The UIC classification is refined to (1'C)C2' for Mallet locomotives.

The 2-6-6-4 was a fairly late development, a product of the superpower steam concept, introduced by the Lima Locomotive Works, which encouraged the use of large fireboxes supported by four-wheel trailing trucks. Such a firebox could sustain a rate of steam generation to meet any demands of the locomotive's cylinders, even at high speed. High speeds were certainly among the design goals for a 2-6-6-4; most of the type were intended for use on fast freight trains.

Comeau C/C++

Comeau C/C++ is a compiler for C and C++ produced by Comeau Computing.

Design

The compiler supports several dialects of both the C and C++ languages. It comes with its own version of the Standard C++ library, libcomo, that is based upon the Standard C++ library from Silicon Graphics, but can also be used with the Dinkumware Standard C library.

The compiler is based upon the Edison Design Group C++ frontend, also utilized in the Intel C++ Compiler. Rather than produce an executable directly, Comeau C/C++ outputs C code and requires a separate C compiler in order to produce the final program. Unlike the Intel compiler, Comeau C/C++ can employ several back ends.

Comeau C/C++ has been described as the most standards-conformant C++ compiler. In 2006-2008 it was described as the only mainstream C++ compiler to fully support the export keyword for exported templates.

Standards compliance

Comeau Computing is a founding member of the C++ committee. Comeau Computing's CEO, Greg Comeau, provided one of the early ports of cfront to the PC.
