More about Borland C++ Builder
C++ Builder is a Rapid Application Development Environment, RAD for short, originally developed by Borland and since 2009 owned by Embarcadero Technologies, for writing programs in the C++ programming language currently targeting Windows, iOS, and various versions , macOS, and Android.
C++ Builder combines the Visual Component Library and IDE written in Object Pascal with various C++ compilers.
Most components developed in Delphi can be used in C++Builder with little or no modification, although the reverse is not true, but this restriction is valid only for source code.
Binary code generated by Delphi can be easily linked to binary code generated by C++ Builder and vice versa to generate an executable written in both Object Pascal and C++.
BCB files are an intermediate component generated in the build and link process, executed by C++ Builder.
