A struct in C is a composite data type that allows you to group multiple variables of different data types under a single name. It's used to represent a record or a complex data structure.
Key points about structs:
-
User-defined type: Structs allow programmers to create their own custom data types.
-
Grouping related data: They are useful for grouping related variables that logically belong together.
-
Members: The variables within a struct are called members or fields.
-
Access: Members are accessed using the dot (.) operator.
-
Memory allocation: The members of a struct are stored in contiguous memory locations.
-
Flexibility: Structs can contain any data type, including other structs.
In the given example:
struct my_struct {
int x;
int y;
};This explanation provides a concise overview of structs in C, highlighting their purpose and key characteristics.
