Which of the following best defines a container?
It is a special type of identifier that can reference multiple values or elements.
What key role do functions play in both consistency and functionality?
They enable you to create segments of code that you will reuse.
What BEST describes the purpose of properties in object-oriented programming?

What does “!=” mean in a logical test
that the two values do not equal each other
What accurately describes arrays?

In what situation would you use a vector?
To include a container that can grow or shrink in size as elements are added or removed
What BEST defines the XOR condition?
If either, but not both, condition is TRUE, then the whole statement is TRUE.
What BEST defines the OR condition?
If either condition is TRUE, then the whole statement is TRUE.
What BEST describes the purpose of attributes?
They are values and data types that define the object.
The attributes are stored within the object as fields or private variables.
What BEST describes the purpose of methods?
They define what you can do to an object.
