  2. Substitution failure is not an error - Wikipedia

    en.wikipedia.org/wiki/Substitution_failure_is...

    Here, attempting to use a non-class type in a qualified name (T::foo) results in a deduction failure for f<int> because int has no nested type named foo, but the program is well-formed because a valid function remains in the set of candidate functions.

  3. Name mangling - Wikipedia

    en.wikipedia.org/wiki/Name_mangling

    32-bit compilers emit, respectively: _f _g@4 @h@4 In the stdcall and fastcall mangling schemes, the function is encoded as _name@X and @name@X respectively, where X is the number of bytes, in decimal, of the argument(s) in the parameter list (including those passed in registers, for fastcall).

  4. Type punning - Wikipedia

    en.wikipedia.org/wiki/Type_punning

    Lastly we have the problem wherein the storage of the floating point data may be in big endian or little endian memory order and thus the sign bit could be in the least significant byte or the most significant byte. Therefore the use of type punning with floating point data is a questionable method with unpredictable results.

  5. Forward declaration - Wikipedia

    en.wikipedia.org/wiki/Forward_declaration

    In C++, classes can be forward-declared if you only need to use the pointer-to-that-class type (since all object pointers are the same size, and this is what the compiler cares about). This is especially useful inside class definitions, e.g. if a class contains a member that is a pointer (or a reference) to another class.

  6. Identifier (computer languages) - Wikipedia

    en.wikipedia.org/wiki/Identifier_(computer...

    In computer programming languages, an identifier is a lexical token (also called a symbol, but not to be confused with the symbol primitive data type) that names the language's entities. Some of the kinds of entities an identifier might denote include variables , data types , labels , subroutines , and modules .

  7. Naming convention (programming) - Wikipedia

    en.wikipedia.org/wiki/Naming_convention...

    CLASS words ideally would be a very short list of data types relevant to a particular application. Common CLASS words might be: NO (number), ID (identifier), TXT (text), AMT (amount), QTY (quantity), FL (flag), CD (code), W (work) and so forth. In practice, the available CLASS words would be a list of less than two dozen terms.

  9. Type qualifier - Wikipedia

    en.wikipedia.org/wiki/Type_qualifier

    shared is used for shared data in multi-threading (as volatile was briefly used for in C++). inout is a wildcard used to allow functions that do not modify data (and thus are only concerned with the unqualified type of the data) to return the same qualified type as the input. const and immutable can also be used as storage class specifiers.
