Question

Before a structure variable can be created, the structure must be _________.

Short answer

Answer: The structure must be defined.

Step-by-step solution

Understand the concept of structures in programming

Structures in programming are used to group different data types under a single name. Before we can create a structure variable, we have to first define the structure's data types and variables, which is known as defining the structure template. Once the structure template is defined, we can then create structure variables.

Fill in the blank with the appropriate term

Since the exercise is asking about the prerequisite step before creating a structure variable, the correct term to complete the statement would be "defined" because we need to define the structure template first. So, the completed statement should be: Before a structure variable can be created, the structure must be defined.
