The actual size of the built-in integral types are machine dependent (see also the Tip Standards Provide Guarantees Regarding the Sizes of Integral Types): //built-in integral types with machine-dependent sizeschar int short long When you need explicit, platform-independent sizes, you can use the following standardized typedef’s instead: int8 //signed 8
In general, a derived class that inherits a pure virtual member function from its abstract base class implements this function. The opposite is also true: a virtual member function that is implemented in a base class can become pure virtual in a derived class. For example: class Base{ virtual void
Char, short, int, and long have implementation-defined sizes. However, Standard C and C++ provide a few guarantees about their sizes. Both standards guarantee that char has at least 8 bits, and that it is not larger than short. Short may not be larger than int and it must occupy at
Always set the Description property of your ActiveX projects (found in Properties) to be prefixed with your company name or initials. That way, all your internal objects and components will be grouped together alphabetically, and you won’t have to search for them in the list.
Although Microsoft Internet Information Server (IIS) eventually removes your unused database objects (called garbage collection), poor coding can squander the server’s resources. If your Web server drags or even fails for no apparent reason, look for connections and objects that haven’t been closed. For a high-volume, data-intensive Web site, you
