Abstract data types in C are a way of organizing and encapsulating data and the operations that can be performed on that data. They allow for the creation of data structures that hide the implementation details from the user, providing a clear interface for interacting with the data. This helps to improve code modularity, reusability, and maintainability. Examples of abstract data types in C include stacks, queues, linked lists, and trees. **
