Question 1

Basic logic components used in programs are called ____.
A) sequence structures
B) selection structures
C) control structures
D) loop structures

Accepted Answer

Basic logic components used in programs are called control structures which include sequence structures, selection structures, and loop structures. Therefore, the best choice is C.

Question 2

The variables and instructions within a module are hidden and contained-that is, ____-which helps to make the module independent of all other modules and therefore reusable.
A) abstracted
B) simplified
C) summarized
D) encapsulated

Accepted Answer

The word "contained" indicates that the variables and instructions are enclosed or encapsulated within the module. This means that they are not accessible from outside the module, making it independent and reusable.

Question 3

In a ____, program steps execute one after another, without interruption.
A) sequence structure
B) selection structure
C) control structure
D) loop structure

Accepted Answer

In a sequence structure, program steps are executed in a specific order, one after the other, without any interruption or condition.

Question 4

____ variables store numbers with decimal places.
A) Integer
B) Numeric
C) Floating point
D) Character

Accepted Answer

Floating point variables are able to store numbers with decimal places, whereas integer variables can only store whole numbers and numeric variables are generally used to store a wide range of numbers, not necessarily with decimal places. Character variables store letters and symbols, not numbers.

Question 5

You ____ a program by using sample data to determine whether the program results are correct.
A) test
B) debug
C) interpret
D) run

Accepted Answer

Testing a program with sample data is a way to check if the program is functioning correctly, so the best choice in this case is "test". Debugging is the process of removing errors from a program, interpreting is explaining the meaning of code or data, and running is simply executing the program.

Question 6

A ____ repeats actions while some condition remains unchanged.
A) sequence structure
B) selection structure
C) control structure
D) loop structure

Accepted Answer

The loop structure is used to repeat actions while some condition remains unchanged. It allows the code to execute repeatedly until a specific condition is met. Examples of loop structures in programming languages include for loops, while loops, and do-while loops.

Question 7

In C++, by default, all structure fields are private.

Accepted Answer

By default, all structure fields are public.

Question 8

Finding syntax errors is much more time consuming for a programmer than finding logical errors.

Accepted Answer

Syntax errors are usually easier to find because they prevent the program from compiling or running, and modern development environments often highlight them or provide immediate feedback. Logical errors, on the other hand, occur when the program runs but produces incorrect results, making them more time-consuming to diagnose and fix.

Question 9

____ variables store whole numbers.
A) Integer
B) Numeric
C) Floating point
D) Character

Accepted Answer

Integer variables are used to store whole numbers, such as 1, 2, 3, etc. Numeric and floating-point variables can store decimal values, while character variables store letters and symbols.

Question 10

The rules of any language make up its ____.
A) syntax
B) vocabulary
C) grammar
D) parser

Accepted Answer

The answer of The rules of any language make up...

Question 11

A ____ is used to perform different tasks based on a condition.
A) sequence structure
B) selection structure
C) control structure
D) loop structure

Accepted Answer

The selection structure is used to perform different tasks based on a condition. It allows a program to choose between two or more paths of execution, depending on the result of a condition. The other options, sequence structure, control structure, and loop structure, do not necessarily involve making a decision based on a condition.

Question 12

A(n) ____ error occurs when you use a statement that, although syntactically correct, doesn't do what you intended.
A) programming
B) debugging
C) logical
D) syntax

Accepted Answer

A logical error is a mistake in the program's logic that produces unintended or undesired results. It is not a syntax error, which is a violation of the programming language's rules. Debugging is the process of identifying and correcting errors in a program. Programming refers to the act of creating or writing code. Therefore, the best choice is C - a logical error.

Question 13

The ____ of a variable defines what kind of values may be stored in a variable and what kind of operations can be performed on it.
A) syntax
B) language
C) input
D) data type

Accepted Answer

The data type of a variable defines what kind of values may be stored in a variable (e.g. integer, float, string) and what kind of operations can be performed on it. Syntax refers to the set of rules that govern the structure of a programming language. Language refers to the actual programming language being used. Input refers to the data that is entered into a program.

Question 14

It is conventional, but not required, to begin object names with a lowercase letter and to begin class names with an uppercase letter.

Accepted Answer

This is a convention followed in many programming languages, but it is not mandatory.

Question 15

Beginning an identifier with a lowercase letter and capitalizing subsequent words within the identifier is a style known as camel casing (for example, yourAge ).

Accepted Answer

This is true.

Question 16

____ is a programming language that supports object-oriented techniques.
A) COBOL
B) C++
C) BASIC
D) FORTRAN

Accepted Answer

C++ supports object-oriented techniques. COBOL, BASIC, and FORTRAN are all considered procedural programming languages and do not have built-in support for object-oriented programming.

Question 17

You cannot write procedural programs in C++.

Accepted Answer

C++ allows for both procedural and object-oriented programming styles, giving programmers the flexibility to choose which approach best suits their needs.

Question 18

In general, C++ programmers use the term "____" when referring to methods.
A) procedures
B) functions
C) subroutines
D) blocks

Accepted Answer

In C++, methods are commonly referred to as "functions." While "procedures" and "subroutines" are also programming concepts, they typically have different meanings and purposes than functions. "Blocks" refers to a section of code enclosed in curly braces {} and can contain multiple statements or expressions.

Question 19

All modern programming languages require that variable names be one word; that is, they cannot include any embedded spaces.

Accepted Answer

Variable names in modern programming languages must be a single continuous string of characters without spaces, as spaces would break the syntax and cause errors in code interpretation.

Question 20

Float values are called double-precision numbers.

Accepted Answer

Float values are single-precision, 32-bit representations of real numbers, while double-precision numbers use 64 bits.
