Tables and chains can only be used to manage similar data, and therefore the need for something to manage different data groups such as a student identifier, a class number, a course name, a teacher name and a pincode. In order to manage the different data, we have “structures” in the programming language C.
Structures inside and outside the main function
You can define structures in programming language C both in the main function or outside the main function. If the structure is defined in the main function, it cannot be accessible by other functions and can only be accessible by the main function alone. If the structure is defined outside the main function, all functions can access the structure.
Access the elements in a structure
The points operator is used to access various elements of the structure.
Go from structures to functions
Like any variable, the structures can be transmitted by value or by reference to the functions.
Typedef for structures
The keyword “Typedef” is used to define an alias for an already existing data type. To define the variables, we must use the keyword “structure” with the name of the structure to define the variables. It can be very long and therefore we use Typedef. Typèdes are not simple chain replacements like Macros in C. There is more like type than simple chain replacements.
Nested structures
Various applications of C -programming structures
C -programming structures are used for many applications:
- To define personalized data types such as complex numbers, which are not present in the language.
- To organize a large amount of data that can be stored in different fields.
- To create data structures such as trees, linked lists, etc.
- can be used to return several values from a function.
- To draw a graphic shape on the screen
- Format a disc
- Hide a file in the directory
- Erase the contents of the screen
- and many other applications
I hope it's useful, thank you.
