"C++实现文件系统搜索程序：按关键字查找路径"

以下是使用C语言实现文件系统搜索程序的示例代码： ```c #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX_PATH_LENGTH 100 typedef struct Node { char name[MAX_PATH_LENGTH]; struct Node* children; struct Node* next; } Node; Node* createNode(char* name) { Node* newNode = (Node*)malloc(sizeof(Node)); strcpy(newNode->name, name); newNode->children = NULL; newNode->next = NULL; return newNode; } void insertChild(Node* parent, Node* child) { if (parent->children == NULL) { parent->children = child; } else { Node* current = parent->children; while (current->next != NULL) { current = current->next; } current->next = child; } } void printPath(Node* node, int level) { for (int i = 0; i < level; i++) { printf("-"); } printf("%s ", node->name); Node* current = node->children; while (current != NULL) { printPath(current, level + 1); current = current->next; } } void searchKeyword(Node* node, char* keyword) { if (strstr(node->name, keyword) != NULL) { printf("Found: %s ", node->name); } Node* current = node->children; while (current != NULL) { searchKeyword(current, keyword); current = current->next; } } int main() { Node* root = createNode("root"); Node* folder1 = createNode("folder1"); Node* file1 = createNode("file1.txt"); Node* file2 = createNode("file2.txt"); insertChild(folder1, file1); insertChild(folder1, file2); insertChild(root, folder1); Node* folder2 = createNode("folder2"); Node* file3 = createNode("file3.txt"); Node* file4 = createNode("file4.txt"); insertChild(folder2, file3); insertChild(folder2, file4); insertChild(root, folder2); Node* folder3 = createNode("folder3"); Node* file5 = createNode("file5.txt"); insertChild(folder3, file5); insertChild(root, folder3); Node* folder4 = createNode("folder4"); Node* file6 = createNode("file6.txt"); insertChild(folder4, file6); insertChild(root, folder4); printf("File System Structure: "); printPath(root, 0); char keyword[MAX_PATH_LENGTH]; printf("Enter keyword to search: "); scanf("%s", keyword); printf("Search Results: "); searchKeyword(root, keyword); return 0; } ``` 这段代码首先定义了一个`Node`结构体，用于表示文件夹或文件节点。然后，通过`createNode`函数创建节点，并通过`insertChild`函数将子节点插入父节点中。`printPath`函数用于打印文件系统的层级结构，`searchKeyword`函数用于搜索包含指定关键字的路径。 在`main`函数中，我们创建了一个示例的文件系统结构，并打印出来。然后，用户可以输入关键字进行搜索，程序将输出包含关键字的路径。 请注意，这只是一个简单的示例代码，实际的文件系统搜索程序可能需要更复杂的逻辑和功能。
