Jackson asserted that this program structure was almost always wrong, and encouraged programmers to look for more complex data structures. In Chapter 3 of Principles of Program Design [1] Jackson presents two versions of a program, one designed using JSP, the other using the traditional single-loop structure. Here is his example, translated ...
Pictorial menu for a digital camera. A user chooses an option from a menu by using an input device. Some input methods require linear navigation: the user must move a cursor or otherwise pass from one menu item to another until reaching the selection. On a computer terminal, a reverse video bar may serve as the cursor.
A piece of software that: interprets user input into commands the computer can understand, produces user feedback based on user input and the system's state. Consider for example the process of deleting a file using a contextual menu. This assumes the existence of a mouse (input device), a screen (output device), and a piece of code that paints ...
Feature selection techniques are used for several reasons: simplification of models to make them easier to interpret, [1] shorter training times, [2] to avoid the curse of dimensionality, [3] improve the compatibility of the data with a certain learning model class, [4] to encode inherent symmetries present in the input space.

The minimum number of test cases is the number of classes in the classification with the most containing classes. In the second step, test cases are composed by selecting exactly one class from every classification of the classification tree. The selection of test cases originally [3] was a manual task to be performed by the test engineer.
Text selection is associated with the cut, copy and paste operations and done with a cursor, caret navigation or touch.; Image editing applications can feature specialized graphical tools for the selection and modification of areas and shapes or to interact with colours, such as the magic wand selection tool, the lasso selection tool, the marquee selection (bounding box), or the color picker.
A collection of objects or classes through which a program can examine and manipulate some specific parts of its world. In other words, the object-oriented interface to some service or system. Such an interface is said to be the object model of the represented service or system.
Software construction is a software engineering discipline. It is the detailed creation of working meaningful software through a combination of coding, verification, unit testing, integration testing, and debugging. It is linked to all the other software engineering disciplines, most strongly to software design and software testing. [1]
