A C structure or User defined datatype is also called ________.a.Derived data typeb.Secondary data typec.Aggregate data typed.All of the options

Break Down the Problem

1. Identify what a C structure or user-defined datatype is called.
2. Analyze the provided options to determine the correct classification.

Relevant Concepts

• Derived Data Type: A type that is created from existing types. In C, structures (struct) can be considered derived data types because they allow for the creation of complex data types.
• Secondary Data Type: This is not a commonly used term in C programming.
• Aggregate Data Type: This refers to a data type that can hold multiple values (like arrays and structures), thus it is also relevant in this context.
• All of the options: This suggests that if multiple options are correct, this one might be the answer.

Analysis and Detail

1. A structure in C is a user-defined datatype used to group different data types together.
2. "Derived data type" accurately describes a structure because it is built upon existing data types.
3. "Aggregate data type" is also applicable since a structure aggregates multiple data types.

Verify and Summarize

Upon examination of the definitions and classifications, the correct options for what a C structure is called include both derived and aggregate data types. Since "All of the options" includes these two valid classifications, it can be selected as the correct answer.

Final Answer

d. All of the options
