Question 1

C# offers a feature called garbage collection that automatically reclaims memory no longer needed by the program.

Accepted Answer

C# uses garbage collection as part of the .NET framework to automatically manage memory by reclaiming memory allocated to objects that are no longer in use by the program, thus preventing memory leaks.

Question 2

C++ is in fact a "subset" of C, meaning that all of the C++ language is part of C.

Accepted Answer

C++ is actually a superset of C, meaning that while it includes all of C's functionality, it also adds its own features and capabilities that are not present in C.

Question 3

Java is the language used to frame database queries. _________________________

Accepted Answer

SQL (Structured Query Language) is the language used to frame database queries, not Java. Java can be used to connect to databases and execute SQL queries, but the queries themselves are written in SQL.

Question 4

Logic programming languages are sometimes called declarative languages. _________________________

Accepted Answer

Logic programming languages, such as Prolog, are considered declarative because they focus on expressing what to solve rather than how to solve it, allowing the program to determine the execution path based on the logic provided.

Question 5

FORTRAN does allow the use of external libraries.

Accepted Answer

FORTRAN supports the use of external libraries, which allows for the extension of its capabilities by incorporating pre-written code and functions from other sources.

Question 6

Writing all computer programs in the same programming language would be more efficient because all languages meet essentially the same needs.

Accepted Answer

Different programming languages are designed with specific purposes in mind, offering unique features, efficiencies, and levels of abstraction suitable for various types of tasks. This diversity allows developers to choose the most appropriate language for a given project, optimizing performance, ease of development, and maintainability.

Question 7

The use of parallelism always reduces processing time because subtasks are being executed concurrently.

Accepted Answer

Parallelism does not always reduce processing time due to overheads such as task distribution and result collection, and it can be limited by factors like data dependencies and hardware capabilities.

Question 8

Unlike FORTRAN, COBOL, C, C++, and Ada, which were carefully developed as programming languages, ____________________, a modern, object-oriented language, was almost an accident.

Accepted Answer

The answer of Unlike FORTRAN, COBOL, C, C++, and Ada,...

Question 9

Lady Ada Lovelace is regarded as the world's first programmer on the basis of her correspondence with Charles Babbage and her published notes on his work with the Analytic Engine.

Accepted Answer

Ada Lovelace is considered the world's first programmer because of her work on Charles Babbage's Analytical Engine, where she wrote what is recognized as the first algorithm intended to be processed by a machine.

Question 10

Much of the processing in the business world concerns updating "transaction files" with changes from "master files."

Accepted Answer

In the business world, the process typically involves updating "master files" with changes from "transaction files." Transaction files contain individual transactions that have occurred over a period, which are then used to update the master files that hold the current state of information.

Question 11

Although C++ supports the basic arithmetic operations of addition, subtraction, multiplication, and division by providing simple operators (+, −, *, /)to do these tasks, there is no operator for exponentiation-that is, raising a value to a power.

Accepted Answer

C++ does not have a built-in operator for exponentiation; instead, the pow function from the or library is typically used for this purpose.

Question 12

Procedural languages act the same regard to the details of assigning a new value to a variable, in the mechanisms, the language provides for directing the flow of control through conditional and looping statements, and in the statement forms that control input and output.

Accepted Answer

Procedural languages may share common principles, such as the use of variables, control flow statements, and I/O operations, but they can differ in syntax and specific mechanisms for implementing these features.

Question 13

The majority of business transactions, billions of them per day, are still done on ____________________ code that has now been updated and is likely to continue to run for the foreseeable future.

Accepted Answer

The answer of The majority of business transactions, billions of...

Question 15

At some point, an increase in the _______ of processors can become more of a hindrance than a help, due to the extra data communication required.

Accepted Answer

The answer of At some point, an increase in the...

Question 16

COBOL and ____________________ were the dominant high-level languages of the 1960s and 1970s.

Accepted Answer

The answer of COBOL and ____________________ were the dominant high-level...

Question 17

C programs cannot make use of low-level information such as knowledge of where data are stored in memory. _________________________

Accepted Answer

C programs can directly access memory addresses using pointers, allowing manipulation and storage of data at specific memory locations.

Question 18

Early versions of FORTRAN did not include a while loop mechanism. _________________________

Accepted Answer

Early versions of FORTRAN (up to FORTRAN IV) did not include a while loop mechanism; instead, they used DO loops for iteration, which were less flexible than the while loops found in more modern programming languages.

Question 19

Early versions of FORTRAN allowed the use of mathematical symbols such as to compare two quantities.

Accepted Answer

Early versions of FORTRAN used keywords and specific characters for operations and comparisons, not the mathematical symbols we commonly use today for such tasks.

Question 20

Scripting language or script code fragments can be embedded in _______ to make those pages active rather than static.

Accepted Answer

The answer of Scripting language or script code fragments can...
