Question 1

It is a common mistake to use = instead of ____.&#10;A) ||&#10;B) &&&#10;C) ==&#10;D) !=

Accepted Answer

The correct operator for comparing two values for equality is ==, not =, which is used for assignment. Options A and B are logical operators used for conditional statements, and option D is used for checking inequality.

Question 2

Consider the following segment of code:&#10;Char genderCode;&#10;Cout > genderCode;&#10;If(genderCode == 'F')&#10;Cout&#10;What will appear on the screen if the user enters 'M'?&#10;A) &#34;Female&#34;&#10;B) &#34;Male&#34;&#10;C) &#34;Invalid code&#34;&#10;D) &#34;&#34;

Accepted Answer

B

Question 3

You must always surround a single statement after an if with curly braces.

Accepted Answer

In many programming languages, including Java and C++, if a single statement follows an if condition, curly braces are not required; the statement will be executed if the condition is true.

Question 4

Almost every C++ expression has a numeric value, and any C++ expression can be evaluated as part of an if statement.

Accepted Answer

Every C++ expression has a numeric value, and any expression can be evaluated in an if statement where the result is treated as a boolean value (true or false).

Question 5

The Boolean expression used in an if statement is often a comparison, such as &#34;x greater than y,&#34; but in C++ it can also be a number or a(n) ____.&#10;A) arithmetic expression&#10;B) logical expression&#10;C) character&#10;D) relational expression

Accepted Answer

The Boolean expression used in an if statement can be an arithmetic expression which evaluates to a numeric value, with non-zero values corresponding to true and zero values corresponding to false.

Question 6

Consider the following segment of code:&#10;If(vacationDays = 0)&#10;Cout&#10;What error can you identify?&#10;A) The code assumes indentation has a logical purpose.&#10;B) A semicolon is incorrectly inserted.&#10;C) There are no curly braces.&#10;D) An assignment operator is used in a comparison.

Accepted Answer

The condition in the if statement uses the assignment operator (=) instead of the comparison operator (==), which will cause a logical error. The correct code should use the comparison operator as follows: if(vacationDays == 0) cout; Also, a complete statement should be inserted after the cout, such as cout<<"No vacation days left"; or cout<<"You can take a vacation now";

Question 7

An else must always be associated with an if , and vice versa.

Accepted Answer

An "else" must be associated with an "if" to provide an alternative path when the "if" condition is not met, but an "if" statement can exist without an accompanying "else" statement.

Question 8

Consider the following segment of code:&#10;If (driverAge&#10;What error can you identify?&#10;A) The code makes unnecessary comparisons.&#10;B) A semicolon is incorrectly inserted.&#10;C) There are no curly braces.&#10;D) The programmer did not take into account that C++ is case sensitive.

Accepted Answer

The if statement lacks curly braces, which may cause unexpected behavior if multiple statements are intended to be executed within the conditional statement block.

Question 9

Consider the following segment of code:&#10;If(vacationDays = 0)&#10;Cout&#10;What will be the output on screen if vacationDays is 0?&#10;A) &#34;No vacation days available&#34;&#10;B) &#34;You have vacation days coming&#34;&#10;C) &#34;&#34;&#10;D) Nothing, because the code will not compile.

Question 10

The ____ surrounding the evaluated expression in an if statement are essential.&#10;A) curly braces&#10;B) angle brackets&#10;C) parentheses&#10;D) square brackets

Accepted Answer

The parentheses surrounding the evaluated expression in an if statement are essential to indicate the condition being tested. Without the parentheses, the statement would not make sense to the compiler.

Question 11
