How do you define a struct?

A struct (short for structure) is a data type available in C programming languages, such as C, C++, and C#. It is a user-defined data type that can store multiple related items. A struct variable is similar to a database record since it may contain multiple data types related to a single entity.

What does typedef struct mean in C?

The C language contains the typedef keyword to allow users to provide alternative names for the primitive (e.g.,​ int) and user-defined​ (e.g struct) data types. Remember, this keyword adds a new name for some existing data type but does not create a new type.

Where is struct defined in C?

Structure is a user-defined datatype in C language which allows us to combine data of different types together. Structure helps to construct a complex data type which is more meaningful.

Is a house a solid structure?

Figure 4.12 A house is built from solid structures that are put together to form a frame. The walls and the roof form a covering around the frame. Designers consider the form and the function of a structure and the forces that act on it. Structures that have the same function may have very different forms.
