如何将文件存储在二叉树结构中，然后输出它们

Question

我有以下代码

#include <stdio.h>
#include <stdlib.h>
struct node
{
    int data;
    struct node *left;
    struct node *right;
};

/* newNode() allocates a new node with the given data and NULL left and
 right pointers. */
struct node* newNode(int data)
{
    // Allocate memory for new node
    struct node* node = (struct node*)malloc(sizeof(struct node));
    node->data = data;

    // Initialize left and right children as NULL
    node->left = NULL;
    node->right = NULL;
    return(node);
}

int main(int argc, const char * argv[])
{
    printf("You Typed the following %s", argv[1]);

    /*create root*/
    struct node *root = newNode(1);
    /* following is the tree after above statement
     1
     /   \
     NULL  NULL
     */

    root->left        = newNode(2);
    root->right       = newNode(3);
    /* 2 and 3 become left and right children of 1
     1
     /   \
     2      3
     /    \    /  \
     NULL NULL NULL NULL
     */

    root->left->left  = newNode(4);
    /* 4 becomes left child of 2
     1
     /       \
     2          3
     /   \       /  \
     4    NULL  NULL  NULL
     /  \
     NULL NULL
     */

    getchar();
    return 0;
}

在内存中生成二叉树。我的计划是将文件指针加载到＆＃34;节点＆＃34;这棵树这些文件来自命令行参数

然后根据用户输入我想在树中向左（或向右），当一个节点被击中时，它应该打印出文件内容等等......

我该怎么做？ 非常感谢任何帮助
