In the C programming language, structures (structs) and the typedef keyword play pivotal roles in organizing and enhancing the flexibility of your code. They provide a way to define custom data types, which can encapsulate multiple data members of different types, creating more complex and meaningful data structures.
A structure is a composite data type that allows you to group together variables of various types under a single name. Each member of a structure can be a different data type, such as integers, floats, characters, or even other structures. Structures enable you to represent complex entities, like employees or students, by combining relevant data into a single unit. Accessing members of a structure is done using the dot (.) operator.
Typedef is a C keyword that allows you to create custom type synonyms. It provides a way to define more expressive names for existing data types, enhancing code readability and maintainability. By using typedef, you can make your code more self-documenting and improve its portability. For example, you can define a new name for a structure, making it easier to declare variables of that type.
