True or False A structure declaration does not define a variable.

Short Answer

Expert verified
True

Step by step solution

01

Understand the concept of a structure declaration

In programming, a structure is a user-defined data type that allows bundling variables of different data types under a single name. A structure declaration is a template for creating instances of this structure. It provides information about the type and size of the various members of the structure, but it does not reserve any memory space or define any variables itself.
02

Determine if a structure declaration defines a variable

Considering that a structure declaration is merely a template and does not reserve memory space for any variables, we can conclude that a structure declaration does not define a variable.
03

Conclude the answer

Therefore, the given statement "A structure declaration does not define a variable" is True.
