在C語言中，數據結構可以通過定義結構體來實現。以下是一些常見的數據結構的使用方法示例：

1. 鏈表：

#include <stdio.h>
#include <stdlib.h>

struct Node {
    int data;
    struct Node* next;
};

int main() {
    struct Node* head = NULL;
    
    // 創建節點并添加到鏈表
    struct Node* node1 = (struct Node*)malloc(sizeof(struct Node));
    node1->data = 1;
    node1->next = NULL;
    
    head = node1;
    
    struct Node* node2 = (struct Node*)malloc(sizeof(struct Node));
    node2->data = 2;
    node2->next = NULL;
    
    node1->next = node2;
    
    // 遍歷鏈表并打印節點的數據
    struct Node* current = head;
    while (current != NULL) {
        printf("%d\n", current->data);
        current = current->next;
    }
    
    return 0;
}

2. 棧：

#include <stdio.h>

#define MAX_SIZE 100

struct Stack {
    int data[MAX_SIZE];
    int top;
};

void push(struct Stack* stack, int value) {
    if (stack->top == MAX_SIZE - 1) {
        printf("Stack is full.\n");
        return;
    }
    
    stack->data[++stack->top] = value;
}

int pop(struct Stack* stack) {
    if (stack->top == -1) {
        printf("Stack is empty.\n");
        return -1;
    }
    
    return stack->data[stack->top--];
}

int main() {
    struct Stack stack;
    stack.top = -1;
    
    push(&stack, 1);
    push(&stack, 2);
    
    printf("%d\n", pop(&stack));
    printf("%d\n", pop(&stack));
    
    return 0;
}

3. 隊列：

#include <stdio.h>

#define MAX_SIZE 100

struct Queue {
    int data[MAX_SIZE];
    int front, rear;
};

void enqueue(struct Queue* queue, int value) {
    if (queue->rear == MAX_SIZE - 1) {
        printf("Queue is full.\n");
        return;
    }
    
    queue->data[++queue->rear] = value;
}

int dequeue(struct Queue* queue) {
    if (queue->front > queue->rear) {
        printf("Queue is empty.\n");
        return -1;
    }
    
    return queue->data[queue->front++];
}

int main() {
    struct Queue queue;
    queue.front = 0;
    queue.rear = -1;
    
    enqueue(&queue, 1);
    enqueue(&queue, 2);
    
    printf("%d\n", dequeue(&queue));
    printf("%d\n", dequeue(&queue));
    
    return 0;
}

以上是一些常見數據結構的使用方法示例，當然還有其他更復雜的數據結構和操作方式，可以根據具體需求選擇合適的數據結構。
