B)SSL
C)Fetch
D)none of these

Accepted Answer

The MySQLi functions are specifically designed to access MySQL database servers, hence the correct answer is A) MySQL. MySQLi stands for "MySQL Improved" and is an extension used in PHP to provide an interface with MySQL databases.

C)S_Array()
D)D_array()

Accepted Answer

The correct function for fetching a result row as an associative array, a numeric array, or both is fetch_array().

Question 14

An inherited class is defined by using the ______ keyword.
A)extends
B)constructor
C)object
D)none of these

Accepted Answer

Question 15

A)true
B)false
C)both a and b
D)none of these

Accepted Answer

Abstract classes and methods are indeed designed such that the parent class can declare a method without implementing it, leaving it to its subclasses to provide the specific implementation.

Question 16

An abstract class is a class that contains at least one abstract method. An abstract method is a method that is declared, but not implemented in the code.
A)true
B)false
C)both a and b
D)none of these

Accepted Answer

The statement is true. An abstract class is indeed a class that contains at least one abstract method, which is a method declared without an implementation.

Question 17

When inheriting from an abstract class, the child class method must be defined with the same name, and the same or a less restricted access modifier.
A)true
B)false
C)both a and b
D)none of these

Accepted Answer

When inheriting from an abstract class, the child class must indeed define methods with the same name as those in the abstract class, and the access modifier of these methods in the child class cannot be more restrictive than those in the abstract class. This ensures that the child class properly implements the abstract methods and adheres to the contract established by the abstract class.

Question 18

Interfaces allow you to specify what methods a class should implement.
A)true
B)false
C)both a and b
D)none of these

Accepted Answer

Interfaces in programming, particularly in object-oriented programming languages, are used to define a contract for classes, specifying what methods the classes must implement without providing the implementation details.

B)abstract class
C)implements
D)None of these

Accepted Answer

Interfaces in Java are declared using the "interface" keyword.

Question 20

A)interface
B)abstract class
C)implements
D)None of these

Accepted Answer

Interfaces cannot have properties, while abstract classes can have.
