Study Notes
Structures in C Programming
- A structure is a collection of variables of different data types that are stored together in memory, allowing to organize and manipulate related data efficiently.
- The purpose of a structure is to group related variables into a single unit, making it easier to work with complex data.
Declaring a Structure in C
- The syntax for declaring a structure in C programming is:
struct tag { type member1; type member2; ... }; - The
structkeyword is used to define a structure, followed by the structure tag (name), and then the member variables enclosed in curly braces.
Structure Members
- The member variables of a structure are called data members or fields.
- Data members can be of different data types, including integers, characters, floats, and even other structures.
Tagged and Untagged Structures
- A tagged structure is a structure with a name, allowing it to be referenced later in the program.
- An untagged structure is a structure without a name, and it is used to create a single instance of the structure.
Creating a New Data Type
- A structure is used to declare a new data type in C programming by defining a collection of variables that can be used together.
- This allows developers to create custom data types that fit their specific needs, making the code more efficient and easier to understand.
