TScript is an object-oriented embeddable scripting language for C++ that supports hierarchical transient typed variables (TVariable). Its main design criterion is to create a scripting language that can interface with C++, transforming data and returning the result. This enables C++ applications to change their functionality after installation.
C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions.
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 ...
The most vexing parse is a counterintuitive form of syntactic ambiguity resolution in the C++ programming language. In certain situations, the C++ grammar cannot distinguish between the creation of an object parameter and specification of a function's type. In those situations, the compiler is required to interpret the line as a function type ...
Eventually this gets to the clone() method of Object (the uppermost class), which creates a new instance of the same class as the object and copies all the fields to the new instance (a "shallow copy"). If this method is used, the class must implement the Cloneable marker interface, or else it will throw a "Clone Not Supported Exception". After ...
The string is an object (a sequence of characters between single quotes is the syntax for literal strings), created by the compiler at compile time. In the original Parc Place image, the glyph of the underscore character _ appeared as a left-facing arrow ← (like in the 1963 version of the ASCII code).
Class-based object-oriented programming languages support objects defined by their class. Class definitions include member data. Class definitions include member data. Message passing is a key concept, if not the main concept, in object-oriented languages.
Function object: with a single method (in C++, the function operator, operator()) it acts much like a function; Immutable object: does not change state after creation; First-class object: can be used without restriction; Container object: contains other objects; Factory object: creates other objects
