0 Se hela listan på de.wikibooks.org The parameter list for a comparison operator or an arithmetic operator must always contain two parameters, with the exception of the unary minus, where only one parameter is needed.

Note: Because of Delphi's operator precedence, the order in which arithmetic operations are calculated is not necessarily the same as the order you type them, just like on a scientific calculator. You can use parentheses to group operations, and the parenthesised operations will happen first.

The most common use for pointers in Delphi is interfacing to C and C++ code, which includes accessing the Windows API. Windows API functions use a number of data types that might be unfamiliar to the Delphi programmer. Most of the parameters in calling API functions are pointers to some data type. Class Operators in Delphi Nicholas, objects (including temporary ones) are reference counted, and the reference count is decreased when they go out of scope (typically at the end statement of a method, if they are declared locally). If there only one reference, they are destroyed. Common mistake in writing logical expression is not paying attention of operator precedence (which operator evaluated first).
