The cursor for the Windows Command Prompt (appearing as an underscore at the end of the line). In most command-line interfaces or text editors, the text cursor, also known as a caret, [4] is an underscore, a solid rectangle, or a vertical line, which may be flashing or steady, indicating where text will be placed when entered (the insertion point).
Cursor (databases), a control structure that enables traversal over the records in a database; Cursor, a value that is the position of an object in some known data structure, a predecessor of pointers; Cursor (slide rule), indicates corresponding points on scales that are not adjacent to each other
A pointer a pointing to the memory address associated with a variable b, i.e., a contains the memory address 1008 of the variable b.In this diagram, the computing architecture uses the same address space and data primitive for both pointers and non-pointers; this need should not be the case.
Huh? The article is called " pointers " people. You need code! —Preceding unsigned comment added by 137.30.122.155 18:58, 10 April 2011 (UTC) I disagree! Code is precise, and pointers are a matter of programming. As someone who programs, I find this good and correct. Mfwitten 19:51, 10 April 2011 (UTC)
At runtime, this program creates three separate heap allocations. A flow-insensitive pointer analysis would treat these as a single abstract memory location, leading to a loss of precision. Many flow-insensitive algorithms are specified in Datalog, including those in the Soot analysis framework for Java. [7]
Function pointers allow different code to be executed at runtime. They can also be passed to a function to enable callbacks. Function pointers are supported by third-generation programming languages (such as PL/I, COBOL, Fortran, [1] dBASE dBL [clarification needed], and C) and object-oriented programming languages (such as C++, C#, and D). [2]
Iterators generalize pointers to elements of an array (which indeed can be used as iterators), and their syntax is designed to resemble that of C pointer arithmetic, where the * and -> operators are used to reference the element to which the iterator points and pointer arithmetic operators like ++ are used to modify iterators in the traversal ...
Smart pointers can facilitate intentional programming by expressing, in the type, how the memory of the referent of the pointer will be managed. For example, if a C++ function returns a pointer, there is no way to know whether the caller should delete the memory of the referent when the caller is finished with the information.
