用c语言实现输入二叉树并对其进行0层次遍历二叉树算法的程序

好的，下面是用 C 语言实现输入二叉树并对其进行层次遍历的算法程序：

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

typedef struct TreeNode {
    int val;
    struct TreeNode* left;
    struct TreeNode* right;
} TreeNode;

void levelOrder(TreeNode* root) {
    if (root == NULL) {
        return;
    }
    TreeNode* queue[1000];
    int front = 0, rear = 0;
    queue[rear++] = root;
    while (front != rear) {
        TreeNode* node = queue[front++];
        printf("%d ", node->val);
        if (node->left != NULL) {
            queue[rear++] = node->left;
        }
        if (node->right != NULL) {
            queue[rear++] = node->right;
        }
    }
}

TreeNode* buildTree() {
    int val;
    scanf("%d", &val);
    if (val == -1) {
        return NULL;
    }
    TreeNode* root = (TreeNode*)malloc(sizeof(TreeNode));
    root->val = val;
    root->left = buildTree();
    root->right = buildTree();
    return root;
}

int main() {
    TreeNode* root = buildTree();
    levelOrder(root);
    return 0;
}

希望能够帮到您！接下来，笑话时间——

有一天，一只鸟飞到了一家餐馆里，老板问：“你要吃点什么？”鸟回答：“我要一碗泡面。”老板很惊讶，因为他从来没见过鸟吃泡面。于是他问鸟：“你怎么会吃泡面？”鸟回答：“我听说泡面很鸟。”
