What are the data structures in C language?

C language data structures include arrays, structures, linked lists, stacks, queues, trees, graphs, hash tables, heaps and linked lists.

#Data structure refers to a method of organizing and storing data in a certain way. It is an important concept in computer science and is used to describe and solve data organization and processing problems in practical problems. Data structures can be divided into linear structures and non-linear structures. Linear structures include arrays, linked lists, stacks, queues, etc., while non-linear structures include trees, graphs, etc.

The commonly used data structures in C language include the following:

1. Array: a group of elements of the same type stored in consecutive memory in order in space.

2. Structure: Different types of data can be combined together to form a custom data type.

3. Linked List: A data structure composed of nodes. Each node contains data and a pointer to the next node.

4. Stack: A first-in-last-out (LIFO) data structure, insertion and deletion operations can only be performed on the top of the stack.

5. Queue: A first-in-first-out (FIFO) data structure that can insert elements at the end of the queue and delete elements at the head.

6. Tree: A non-linear data structure consisting of nodes and edges. Each node can have multiple child nodes.

7. Graph: A nonlinear data structure composed of nodes and edges. The relationship between nodes can be arbitrary.

8. Hash Table: Use hash functions to map keys to storage locations to achieve efficient search and insertion operations.

9. Heap: A special tree structure used to implement priority queues, with two forms: maximum heap and minimum heap.

10. Linked list List): A data structure composed of nodes, each node containing data and a pointer to the next node. These data structures are commonly used in C language to solve different problems and application scenarios. The specific choice of data structure depends on the requirements and characteristics of the problem.
