Classes are self-describing user-defined reference types. Essentially all types in the .NET Framework are classes, including structs and enums, that are compiler generated classes. Class members are private by default, but can be declared as public to be visible outside of the class or protected to be visible by any descendants of the class.
The resulting C# wrapper has the similar interface of the C++ counterpart with the parameter type converted to the .NET code. This tool recognizes template classes which is not exported from the C++ DLL and instantiates the template class and export it in a supplement DLL and the corresponding C++ interface can be used in .NET.
C# supports classes with properties. The properties can be simple access-er functions with a backing field, or implement arbitrary getter and setter functions. A property is read-only if there's no setter. Like with fields, there can be class and instance properties. The underlying methods can be virtual or abstract like any other method. [82]
In C and C++ short, long, and long long types are required to be at least 16, 32, and 64 bits wide, respectively, but can be more. The int type is required to be at least as wide as short and at most as wide as long , and is typically the width of the word size on the processor of the machine (i.e. on a 32-bit machine it is often 32 bits wide ...
The RETURN instruction pops the return address from the stack into the instruction pointer and execution resumes at that address. (Examples: x86, PDP-11) In architectures such as the Motorola 96000, the stack area may be allocated in a separate address space, which is called 'Stack Memory Space', [22] distinct from the main memory address space ...
Objects belonging to type-compatible classes (for example siblings in an inheritance hierarchy) will have virtual method tables with the same layout: the address of a given method will appear at the same offset for all type-compatible classes. Thus, fetching the method's address from a given offset into a virtual method table will get the ...
And even if methods owned by the base class call the virtual method, they will instead be calling the derived method. Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding means having two methods with the same method name and parameters. Overloading is also referred to as ...
On the mainframe operating system MUSIC/SP, if one asks for the file name "X", one is making an unqualified reference either to the file X in the user's library, or to the file X in the common library if the user does not have a file named X and one does exist in the common library. If, however, one were to refer to "*COM:X" one is using a ...
