Question 1

Generally speaking, programmers do not have much interaction with the people for whom they write programs.

Answer

true

Question 2

It is much harder to write programs in assembly language than in machine language.

Answer

true

Question 3

Like your digital video recorder, cell phone, and coffee maker, a computer is also a mechanism that can be programmed.

Answer

true

Question 4

The process of translating a computer solution into a language that a computer can understand is called coding.

Answer

true

Question 5

A repetition structure can only include one instruction.

Answer

true

Question 6

High-level languages are a vast improvement over machine and assembly languages, because they allow the programmer to use instructions that more closely resemble the English language.

Answer

true

Question 7

Programmers usually work alone, not in teams.

Answer

true

Question 8

The assembly languages represent the only way to communicate directly with the computer

Answer

true

Question 9

Programmers use a variety of special languages, called programming languages, to communicate with the computer.

Answer

true

Question 10

Typical tasks performed by a computer programmer include analyzing a problem statement or project specification, planning an appropriate solution, and converting the solution to a language that the computer can follow.

Answer

true

Question 11

An interpreter translates the entire program before running it; a compiler translates the program line by line as the program is running.

Answer

true

Question 12

The repetition structure repeats one or more instructions until some condition is met, at which time the repetition structure ends.

Answer

true

Question 13

The first step in solving a familiar problem is to analyze the problem.

Answer

true

Question 14

One very important component of any problem is the goal of solving the problem.

Answer

true

Question 15

The first step in solving a familiar problem is to analyze the problem.

Answer

true

Question 16

IPO stands for Information, Processing, and Output.

Answer

true

Question 17

The term hand-tracing refers to the fact that the programmer uses a pencil and paper to follow each of the steps in the algorithm by hand.

Answer

true

Question 18

The term desk-checking refers to the fact that the programmer reviews the algorithm while seated at his or her desk rather than in front of the computer.

Answer

true

Question 19

You desk-check an algorithm to verify that it is not missing any steps, and that the existing steps are correct and in the proper order.

Answer

true

Question 20

When analyzing a problem, you always search first for the input, and then for the output.

Answer

true

Question 21

You can desk-check an algorithm using its pseudocode but not its flowchart.

Answer

true

Question 22

Before you begin the desk-check, you first choose a set of sample data for the input values, which you then use to manually compute the expected output values.

Answer

true

Question 23

The fundamental data types are the basic data types built into the C++ language.

Answer

true

Question 24

You should assign a descriptive name to each variable and named constant used in a program.

Answer

true

Question 25

It is important to initialize memory locations using values that have the same data type as the memory location.

Answer

true

Question 26

After declaring a named constant, you can refer to that constant using its name later in the program.

Answer

true

Question 27

A variable is a memory location whose value can change during runtime.

Answer

true

Question 28

In C++, you declare a variable using a declaration statement.

Answer

true

Question 29

The binary number system uses only the two digits 0 and 1.

Answer

true

Programming basics: languages, programmers and structures
