The first release of Turbo C++ was made available during the MS-DOS era on personal computers. Version 1.0, running on MS-DOS, was released in May 1990. An OS/2 version was produced as well. Version 1.01 was released on February 28, 1991, running on MS-DOS. The latter was able to generate both COM and EXE programs and was shipped with Borland's Turbo Assembler compiler for Intel x86 processors. The initial version of the Turbo C++ compiler was based on a front end developed by TauMetric. This compiler supported the AT&T 2.0 release of C++. Turbo C++ 3.0 was released in 1991, and came in amidst expectations of the coming release of Turbo C++ for Microsoft Windows. Initially released as an MS-DOS compiler, 3.0 supported C++ templates, Borland's inline assembler, and generation of MS-DOS mode executables for both 8086real mode and 286 protected mode 3.0 implemented AT&T C++ 2.1, the most recent at the time. The separate Turbo Assembler product was no longer included, but the inline-assembler could stand in as a reduced functionality version. Soon after the release of Windows 3.0, Borland updated Turbo C++ to support Windows application development. The Turbo C++ 3.0 for Windows product was quickly followed by Turbo C++ 3.1. It's possible that the jump from version 1.x to version 3.x was in part an attempt to link Turbo C++ release numbers with Microsoft Windows versions; however, it seems more likely that this jump was simply to synchronize Turbo C and Turbo C++, since Turbo C 2.0 and Turbo C++ 1.0 had come out roughly at the same time, and the next generation 3.0 was a merger of both the C and C++ compiler. Starting with version 3.0, Borland segmented their C++ compiler into two distinct product-lines: "Turbo C++" and "Borland C++". Turbo C++ was marketed toward the hobbyist and entry-level compiler market, while Borland C++ targeted the professional application development market. Borland C++ included additional tools, compiler code-optimization, and documentation to address the needs of commercial developers. Turbo C++ 3.0 could be upgraded with separate add-ons, such as Turbo Assembler and Turbo Vision 1.0. Version 4.0 was released in November 1993 and was notable for its robust support of templates. In particular, Borland C++ 4 was instrumental in the development of the Standard Template Library, expression templates, and the first advanced applications of template metaprogramming. With the success of the Pascal-evolved product Delphi, Borland ceased work on their Borland C++ suite and concentrated on C++Builder for Windows. C++Builder shared Delphi's front-end application framework but retained the Borland C++ back-end compiler. Active development on Borland C++/Turbo C++ was suspended until 2006 Version 4.5 was announced on March 20, 1995. New features include multimedia QuickTour, five new games with corresponding source codes. It includes the ObjectWindows Library 2.5, AppExpert, ClassExpert, Object Components Framework.
Version 4.0J supports DOS for PC-9801 and PC/AT. It includes Turbo Debugger 4.0. IDE uses XMS memory. Project manager supports linking OBJ/LIB libraries, integration with Turbo Assembler 4.0J external assembler. Version 5.0J was announced on 1996-07-23. Based on Borland C++ 5.0J, this version includes IDE supporting Windows 95 and NT 3.51, and can compile 16-bit software. It includes ObjectWindows Library 5.0, Borland Database Engine, Visual Database Tools.
Borland Turbo C++ Suite
This version includes Borland C++Builder 1.0, Turbo C++ 4.5 for Windows 3.1, Turbo C++ 3.0 for DOS. Later release replaces C++Builder 1.0 with Borland C++BuilderX Personal Edition.
Turbo C++ 2006
It is a single language version of Borland Developer Studio 2006 for C++ language, originally announced in 2006-08-06, and was released later on 2006-09-05 the same year with Turbo Explorer and Turbo Professional editions. The Explorer edition was free to download and distribute while the Professional edition was a commercial product. In October 2009 Embarcadero Technologies discontinued support of all Turbo C++ 2006 editions. As such, the Explorer edition is no longer available for download and the Professional edition is no longer available for purchase from Embarcadero Technologies. Turbo C++ 2006 was succeeded by C++Builder 2007 before Embarcadero's acquisition of Codegear and dropping support, and official Turbo C++ 2006 page has later redirected a visitor to C++ Builder 2010.
