[Sebesta01-02] ___ is the evaluation criteria for the ease with which programs can be understood

Web Software or Programming Language(s)

[Sebesta01] According to the author. Consider diverse and various domains of programming languages and applications. The World Wide Web is supported by an eclectic collection of languages, ranging from markup languages, such as HTML, which is not a programming language, to general-purpose programming languages, such as Java. Because of the pervasive need for dynamic Web content, some computation capability is often included in the technology of content presentation. This functionality can be provided by embedding programming code in an HTML document. Such code is often in the form of a scripting language, such as JavaScript or PHP. There are also some markup-like languages that have been extended to include constructs that control document processing. This is an example of ____.

Language

[Sebesta03] A(n) ____ is a set of sentences

comments

[Sebesta1-2] A program has its own inline documentation, called ____.

Increased ability to learn new languages.

According to the author. Consider the list of potential benefits of studying concepts of programming languages. One of the benefits would be argued as follows: Computer programming is still a relatively young discipline, and design methodologies, software development tools, and programming languages are still in a state of continuous evolution. This makes software development an exciting profession, but it also means that continuous learning is essential. The process of learning a new programming language can be lengthy and difficult, especially for someone who is comfortable with only one or two languages and has never examined programming language concepts in general. Once a thorough understanding of the fundamental concepts of languages is acquired, it becomes far easier to see how these concepts are incorporated into the design of the language being learned. For example, programmers who understand the concepts of object-oriented programming will have a much easier time learning Java (Arnold et al., 2006) than those who have never used those concepts. This is an example of ____.

Better understanding of the significance of implementation.

According to the author. Consider the list of potential benefits of studying concepts of programming languages. One of the benefits would be argued as follows: In learning the concepts of programming languages, it is both interesting and necessary to touch on the implementation issues that affect those concepts. In some cases, an understanding of implementation issues leads to an understanding of why languages are designed the way they are. In turn, this knowledge leads to the ability to use a language more intelligently, as it was designed to be used. We can become better programmers by understanding the choices among programming language constructs and the consequences of those choices. This is an example of ____.

Readability, Writability, Reliability

According to the author. Consider the list of some important criteria of a programming language. Select the best answer. Simplicity is primarily concerned for this criterion (or criteria).

BNF

[Sebesta01-02] _____ is invented to describe the syntax of Algol 58

PHP

[Sebesta01-02] ______ is the most popular Web server-side programming language

Systems Programming or Programming Language(s)

[Sebesta01] According to the author. Consider diverse and various domains of programming languages and applications. The UNIX operating system is written almost entirely in C, which has made it relatively easy to port, or move, to different machines. Some of the characteristics of C make it a good choice for this programming domain. It is low level, execution efficient, and does not burden the user with many safety restrictions. This is an example of ____.

Artificial Intelligence or Programming Language(s)

[Sebesta01] According to the author. Consider diverse and various domains of programming languages and applications. The first widely used programming language developed for the applications was the functional language LISP (McCarthy et al., 1965), which appeared in 1959. Most AI applications developed prior to 1990 were written in LISP or one of its close relatives. During the early 1970s, however, an alternative approach to some of these applications appeared—logic programming using the Prolog language. This is an example of ____.

Artificial Intelligence or Programming Language(s)

[Sebesta01] According to the author. Consider diverse and various domains of programming languages and applications. This domain is a broad area of computer applications characterized by the use of symbolic rather than numeric computations. Symbolic computation means that symbols, consisting of names rather than numbers, are manipulated. Also, symbolic computation is more conveniently done with linked lists of data rather than arrays. This kind of programming sometimes requires more flexibility than other programming domains. For example, in some applications the ability to create and execute code segments during execution is convenient. This is an example of ____.

Systems Programming or Programming Language(s)

[Sebesta01] According to the author. Consider diverse and various domains of programming languages and applications. This type of software is used almost continuously and so it must be efficient. Furthermore, it must have low-level features that allow the software interfaces to external devices to be written. For IBM mainframe computers, the language was PL/S, a dialect of PL/I. This is an example of ____.

Scientific Applications or Programming Language(s)

[Sebesta01] According to the author. Consider diverse and various domains of programming languages and applications. The early high-level programming languages invented for _____ applications were designed to provide for those needs. Their competition was assembly language, so efficiency was a primary concern. The first language for scientific applications was Fortran. For some applications where efficiency is the primary concern, such as those that were common in the 1950s and 1960s, no subsequent language is significantly better than Fortran, which explains why Fortran is still used. This is an example of ____.

Improved background for choosing appropriate languages.

[Sebesta01] According to the author. Consider the list of potential benefits of studying concepts of programming languages. One of the benefits would be argued as follows: Many professional programmers have had little formal education in computer science; rather, they have developed their programming skills independently or through in- house training programs. Such training programs often limit instruction to one or two languages that are directly relevant to the current projects of the organization. Many other programmers received their formal training years ago. The languages they learned then are no longer used, and many features now available in programming languages were not widely known at the time. The result is that many programmers, when given a choice of languages for a new project, use the language with which they are most familiar, even if it is poorly suited for the project at hand. If these programmers were familiar with a wider range of languages and language constructs, they would be better able to choose the language with the features that best address the problem. This is an example of ____.

[Sebesta01] According to the author. Consider the list of some important criteria of a programming language. Select the best answer. Support for Abstraction is primarily concerned for this criterion (or criteria).

Operator overloading

[Sebesta01] According to the author. Select the best answer. One of the potential problems is _____, in which a single operator symbol has more than one meaning. Although this is often useful, it can lead to reduced readability if users are allowed to create their own overloading and do not do it sensibly.

Readability

[Sebesta01] According to the author. The following description is about _____. Select the best answer. In the 1970s, the software life-cycle concept (Booch, 1987) was developed; coding was relegated to a much smaller role, and maintenance was recognized as a major part of the cycle, particularly in terms of cost. The ease of maintenance is determined in large part by the ____ of programs. This became an important measure of the quality of programs and programming languages.
