Understanding Arrays and Lists in Programming

What is a key characteristic of how arrays store data in memory?

• Data is stored randomly.

• Data is stored contiguously.

• Data is stored in a linked list.

• Data is stored in a hash table.

In most programming languages, what is the starting index for elements in an array?

• 1

• 0

• -1

• Any integer specified by the programmer.

What is a fundamental difference between arrays and lists in terms of the data types they can store?

• Arrays can store multiple data types (heterogeneous), while lists can only store a single data type (homogeneous).

• Arrays can only store a single data type (homogeneous), while lists can store multiple data types (heterogeneous).

• Both arrays and lists can store multiple data types, but arrays are faster.

• Both arrays and lists can only store a single data type, but lists are more memory-efficient.

In a three-dimensional array declared as myArray[5,5,5], how many index values are required to access a specific element?

• One

• Two

• Three

• Five

What is a key distinction between a Python list and a Python tuple?

• A list can store multiple data types, while a tuple can only store one.

• A list is immutable, while a tuple is mutable.

• A list can be modified after creation, while a tuple cannot.

• A list has a fixed size, while a tuple can grow or shrink.
