Question 1

In a switch statement, what keyword is followed by one of the possible values that might equal the switch expression?

Accepted Answer

The "case" keyword is used in a switch statement to specify one of the possible values that the switch expression might equal.

Question 2

You can combine as many AND and OR operators in an expression as needed.

Accepted Answer

In programming and logic, you can combine multiple AND and OR operators in an expression to evaluate complex conditions, as long as the syntax is correct.

Question 3

What character(s) function as the non-conditional Boolean logical inclusive OR operator?

Accepted Answer

A

Question 4

In a situation where you want to perform one action when a Boolean expression evaluates as true and an alternate action when it evaluates as false, otherwise known as a dual-alternative decision, what sort of statement should you use?

Accepted Answer

An if-else statement is used to perform one action when a Boolean expression is true and an alternate action when it is false, making it suitable for dual-alternative decisions.

Question 5

What character(s) function as the conditional OR operator in the C# programming language?

Accepted Answer

In C#, the conditional OR operator is represented by "||". It evaluates the second operand only if the first operand is false, making it a short-circuiting operator.

Question 6

When creating a flowchart or pseudocode representation of a task, what type of structure is one in which one step follows another unconditionally?

Accepted Answer

A sequence is a type of structure in which one step follows another unconditionally.

Question 7

What character(s) function as the non-conditional Boolean logical AND operator in the C# programming language?

Accepted Answer

The '&' character functions as the non-conditional Boolean logical AND operator in C#. It evaluates both operands regardless of the first operand's value.

Question 8

What sort of evaluation involves the evaluation of expressions in each part of a compound, conditional Boolean expression only as much as necessary to determine whether the expression is false?

Accepted Answer

Short-circuit evaluation stops evaluating as soon as the overall truth value is determined, which is efficient for conditional Boolean expressions.

Question 9

What should you use if you wish to execute two or more statements conditionally?

Accepted Answer

A block enclosed within a pair of curly braces allows you to group multiple statements together so they can be executed conditionally as a single unit.

Question 10

When using a switch structure to make decisions within a program, what keyword is used to begin the structure?

Accepted Answer

The "switch" keyword is used to begin a switch structure in programming languages like C, C++, Java, and others.

Question 11

What type of statement can be used to make a single-alternative decision?

Accepted Answer

An if statement can be used to make a single-alternative decision.

Question 12

What conditional operator can be used when you want some action to occur even if only one of two given conditions is true?

Accepted Answer

OR operator is used when you want some action to occur even if only one of two given conditions is true.

Question 13

Flowchart creators use diamond shapes to indicate alternative courses of action.

Accepted Answer

Diamond shapes in flowcharts are used to represent decision points, where alternative courses of action can be taken based on the outcome of the decision.

Question 14

It is illegal to use a block to contain a single statement.

Accepted Answer

In most programming languages, it is not illegal to use a block to contain a single statement; it is often used for clarity or future expansion.

Question 15

When if-else statements are nested, each else is always paired with the most recent unpaired if.

Accepted Answer

In programming, when if-else statements are nested, each else is automatically associated with the closest preceding unmatched if, unless explicitly directed otherwise using braces.

Question 16

What type of structure involves choosing between alternative courses of action based on some value within a program?

Accepted Answer

A decision structure involves choosing between alternative courses of action based on some value within a program.

Question 17

What character(s) do you use to make a conditional AND operator within a C# program?

Accepted Answer

&& is the conditional AND operator in C#.

Question 18

What conditional operator can be used to create a compound Boolean expression as an alternative to if statements?

Accepted Answer

AND is a conditional operator that can be used to create a compound Boolean expression as an alternative to if statements. It returns true if both of its operands are true, and false otherwise.

Question 19

In a switch statement, the keyword return usually terminates each case.

Accepted Answer

In a switch statement, the keyword "break" is typically used to terminate each case, not "return".

Question 20

The if expression that precedes a block in a decision structure is known as what type of statement?

Accepted Answer

The answer of The if expression that precedes a block...
