Borland C++ Builder

C++Builder is a rapid application development (RAD) environment, originally developed by Borland and as of 2009^[update] owned by Embarcadero Technologies, for writing programs in the C++ programming language targeting Windows NT (IA-32 and x64), OS X, iOS and Android. C++Builder combines the Visual Component Library and IDE written in Delphi with a C++ compiler. Most components developed in Delphi can be used in C++Builder with no or little modification, although the reverse is not true, but this constraint is valid only for source code. Binary code generated by Delphi can easily be linked to binary code generated by C++Builder and vice-versa to generate an executable written in both Object Pascal and C++. With this approach we can call C++ from Object Pascal and vice-versa.

C++Builder includes tools that allow drag-and-drop visual development, making programming easier by incorporating a WYSIWYG graphical user interface builder.

C++Builder uses the same IDE as Delphi, and shares many core libraries. Notable shared Delphi (Object Pascal code) and C++ Builder routines include the FastMM4 memory manager, which was developed as a community effort within the FastCode project, the entire UI framework known as the VCL, which is written in Object Pascal, as well as base system routines, many of which have been optimised for both Delphi and C++Builder through the FastCode project.
