Question 1

C# has only one operator, _____, for integer division and floating point division.&#10;A) asterisk ( * )&#10;B) backslash ( \ )&#10;C) forward slash ( / )&#10;D) None of the above.

Accepted Answer

C# uses the forward slash (/) for both integer division and floating point division. The result type depends on the types of the operands.

Question 2

When an application suspends execution at a breakpoint, a_____ appears to the left of the line that contains the next statement to execute.&#10;A) margin indicator bar&#10;B) breakpoint&#10;C) yellow arrow&#10;D) solid maroon circle

Accepted Answer

A yellow arrow typically appears in many development environments to indicate the next statement to be executed when an application is suspended at a breakpoint.

Question 3

To insert a breakpoint, _____the line of code at which you wish to insert the breakpoint.&#10;A) double click&#10;B) triple click&#10;C) click the margin indicator bar next to&#10;D) highlight

Accepted Answer

To insert a breakpoint in most integrated development environments (IDEs), you typically click the margin indicator bar (or gutter) next to the line of code where you want the breakpoint to be. This action does not require highlighting or multiple clicks on the line itself.

Question 4

A process is _____if a value is read from a memory location and is not destroyed.&#10;A) destructive&#10;B) nondestructive&#10;C) valid&#10;D) invalid

Accepted Answer

A process is nondestructive if a value is read from a memory location and is not destroyed, meaning the original data remains intact after the operation.

Question 5

The expression intX _____intY yields the remainder after intX is divided by intY.&#10;A) Mod&#10;B) %&#10;C) *&#10;D) /

Accepted Answer

The % operator in many programming languages, including C, C++, Java, and Python, yields the remainder of the division of the first operand by the second.

Question 6

A flaw in a program is often referred to as a(n)_____ .&#10;A) bug&#10;B) worm&#10;C) virus&#10;D) easter egg

Accepted Answer

A "bug" is the correct term used to describe a flaw or error in a program's code that causes it to operate incorrectly or unexpectedly.

Question 7

In C#, all_____ must be declared, or reported to the compiler by program code.&#10;A) keywords&#10;B) modifiers&#10;C) built-in data types&#10;D) variables

Accepted Answer

Variables in C# must be declared before they are used in the program. This declaration informs the compiler about the variable's name and type, allowing the compiler to allocate appropriate memory space and enforce type safety. Keywords, modifiers, and built-in data types are elements of the language itself and do not need to be declared by the programmer.

Question 8

A(n)____ is a C# built-in data type.&#10;A) bool&#10;B) integ&#10;C) sint&#10;D) bool32

Accepted Answer

A) bool is a built-in data type in C# used to declare variables to store Boolean values, true or false.

Question 9

Variable names correspond to locations _____.&#10;A) in your application code&#10;B) on your application's Form&#10;C) in your computer's memory&#10;D) in a name space

Accepted Answer

Variable names in programming correspond to locations in your computer's memory where data is stored. They serve as references to those memory locations, allowing programmers to access and manipulate data stored there.
