By returning a null object (i.e., an empty list) instead, there is no need to verify that the return value is in fact a list. The calling function may simply iterate the list as normal, effectively doing nothing. It is, however, still possible to check whether the return value is a null object (an empty list) and react differently if desired.
In computing, a null pointer or null reference is a value saved for indicating that the pointer or reference does not refer to a valid object. Programs routinely use null pointers to represent conditions such as the end of a list of unknown length or the failure to perform some action; this use of null pointers can be compared to nullable types ...
Other escape sequences that are found in use in various languages are \000, \x00, \z, or \u0000. A null character can be placed in a URL with the percent code %00. The ability to represent a null character does not always mean the resulting string will be correctly interpreted, as many programs will consider the null to be the end of the string.
Steve Bass of PC World provided a brief review of the 1.1.2 release of WinDirStat, summarizing its usefulness: "Windirstat is [a] colorful and nifty tool to check the makeup of your hard drive -- especially if you're looking for immense files. It scans your drive and produces a treemap that shows each file as a colored rectangle that's ...
An intuitive metric: line of code serves as an intuitive metric for measuring the size of software because it can be seen, and the effect of it can be visualized. Function points are said to be more of an objective metric which cannot be imagined as being a physical entity, it exists only in the logical space.
An early attempt to guarantee void safety was the design of the Self programming language.. The Eiffel language is void-safe according to its ISO-ECMA standard; the void-safety mechanism is implemented in EiffelStudio starting with version 6.1 and using a modern syntax starting with version 6.4.
File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte . A large value is often expressed with a metric prefix (as in megabyte and gigabyte ) or a binary prefix (as in mebibyte and gibibyte ).
Due to the expense of finding the length, many programs did not bother before copying a string to a fixed-size buffer, causing a buffer overflow if it was too long. The inability to store a zero requires that text and binary data be kept distinct and handled by different functions (with the latter requiring the length of the data to also be ...
