What operator is used to select elements within an instance of a structure?

->
.
::
[]

The correct answer is: .

The dot operator, denoted by a period, is used to access elements within a structure. This operator is the standard way of performing member selection and can be applied to any structure instance. The other options, such as the arrow operator (->), scope resolution operator (:), or square brackets ([]) are used for different purposes and may not work with all types of structures. For example, the arrow operator is used for accessing members of a pointer to a struct, while the scope resolution operator is used for accessing members of a namespace in C++. The square brackets are typically used for indexing elements in a data structure like arrays or vectors. Therefore, these options are incorrect as they are not specific to selecting elements within a structure instance.
