Array Indexing and Arrays: Comprehensive Assessment

What is the primary purpose of an array in programming?

• To create complex mathematical calculations
• To define function parameters
• To store a single data type
• To store multiple items under a common name

In the array ['Monkey', 'Penguin', 'Gorilla', 'Turtle'], what is the index of 'Gorilla'?

• 1
• 3
• 2
• 0

Why do programmers start counting array indexes from 0?

• It's a fundamental computer science principle
• To save memory
• It's a random convention
• To make calculations easier

How would you access the first element of an array named 'animals'?

• animals[0]
• animals{0}
• animals[1]
• animals.first()

What is an 'element' in the context of arrays?

• A single object within an array
• A programming language
• A mathematical symbol
• A computer hardware component

In the syntax array_name[index], what does the square bracket notation represent?

• A comment in the code
• A method of accessing specific array elements
• A mathematical operation
• A way to create new arrays

What happens if you try to access an index that doesn't exist in an array?

• The array automatically expands
• It creates a new element
• It typically generates an error
• It returns a null value

Which of the following is a valid array declaration?

• animals = [Monkey, Penguin, Gorilla]
• animals = (Monkey, Penguin, Gorilla)
• animals = {Monkey, Penguin, Gorilla}
• animals = Monkey, Penguin, Gorilla

What is the total number of elements in the array ['Monkey', 'Penguin', 'Gorilla', 'Turtle']?

• 0
• 3
• 4
• 5

If you want to access the last element of an array with 4 elements, which index would you use?

• 3
• 2
• 4
• 1
