Question 1

When you declare a pointer, you insert a(n) ____ in front of the variable name.&#10;A) ampersand&#10;B) asterisk&#10;C) pipe&#10;D) pound sign

Accepted Answer

To declare a pointer, you insert an asterisk (*) in front of the variable name to indicate that the variable will store a memory address rather than a regular value.

Question 2

The ____ of a variable defines where it can be accessed in a program.&#10;A) abstraction&#10;B) scope&#10;C) encapsulation&#10;D) lifetime

Accepted Answer

The scope of a variable determines where in a program the variable can be accessed. This refers to the area of the program where the variable is visible and can be used. The scope can be global (accessible throughout the entire program) or local (only accessible within a specific function or code block).

Question 3

The ____ of a variable is the time during which it is defined-from declaration to destruction.&#10;A) scope&#10;B) duration&#10;C) encapsulation&#10;D) lifetime

Accepted Answer

The lifetime of a variable refers to the period during which the variable exists in memory, from its declaration to its destruction.

Question 4

The statement return letter; can be alternatively written as ____. Both statements work identically.&#10;A) return(letter);&#10;B) return:letter;&#10;C) return{letter};&#10;D) return[letter];

Accepted Answer

In JavaScript, the syntax for returning a value from a function is "return value;". The value can be of any data type including a string, number, boolean, object, or function. The syntax for the return statement is not interchangeable with any other syntax. Therefore, only option A is a valid syntax for the return statement in JavaScript.

Question 5

A function declaration is also called a function ____.&#10;A) statement&#10;B) scope&#10;C) call&#10;D) prototype

Accepted Answer

A function declaration is also known as a function prototype as it defines the function's name, parameters, and return type.

Question 6

The statement that executes a function is the function ____.&#10;A) statement&#10;B) alias&#10;C) call&#10;D) expression

Accepted Answer

To actually run or execute a function, we need to use a function call, also known as a function invocation. This is done by writing the function name followed by parentheses (). Therefore, the correct answer is "call".

Question 7

____ variables are those that are known to all functions in a program.&#10;A) Global&#10;B) Local&#10;C) General&#10;D) Modular

Accepted Answer

Global variables are accessible to all functions in a program.

Question 8

____ variables are known only in a limited scope.&#10;A) Global&#10;B) Local&#10;C) Limited&#10;D) Modular

Accepted Answer

Local variables are declared and accessed only within a limited scope, such as within a function or block of code. Global variables, on the other hand, can be accessed and modified from anywhere in the program. Limited and modular are not commonly used terms to describe variable scope.

Question 9

Statements that can never execute are called dead code.

Accepted Answer

Dead code is code that can never execute, either because it is located after a return statement or because it is guarded by a condition that can never be true.

Question 10

____ is also called data hiding.&#10;A) Overloading&#10;B) Overriding&#10;C) Abstraction&#10;D) Encapsulation

Accepted Answer

Encapsulation is the technique of hiding the internal implementation details of an object from the outside world. It is also known as data hiding. Overloading and overriding are related to method or function invocation, while abstraction is related to the concept of hiding unnecessary details while showing only the essential features of an entity.
