Final answer:
To operate over the elements of a STRUCT or ARRAY, they must first be declared and initialized with values. For STRUCTs, all member data must be assigned a value, and for ARRAYs, each element should be initialized. Once initialized, various operations can be performed on the elements.
Step-by-step explanation:
Before you can operate over the elements of a STRUCT or ARRAY, you must first ensure that they are properly declared and initialized with values. A STRUCT in programming is a user-defined data type that allows you to combine data items of different kinds.
An ARRAY is a collection of items stored at contiguous memory locations. The process of initializing a STRUCT or ARRAY ensures that the elements contained within have defined values that can be manipulated or utilized in operations.
For a STRUCT, each member data should be assigned a value before performing operations. Similarly, for an ARRAY, each element should either be initialized to a specific value or be set by some algorithm or function prior to usage.
Only once each element is initialized can logical, arithmetical, or any other form of operation be correctly performed.
