在C语言中,可以使用结构体来表示二叉树节点,然后通过递归的方式来创建二叉树。具体的方法如下:
typedef struct Node {
int data;
struct Node* left;
struct Node* right;
} Node;
Node* createNode(int data) {
Node* newNode = (Node*)malloc(sizeof(Node));
newNode->data = data;
newNode->left = NULL;
newNode->right = NULL;
return newNode;
}
Node* createBinaryTree() {
Node* root = createNode(1);
root->left = createNode(2);
root->right = createNode(3);
root->left->left = createNode(4);
root->left->right = createNode(5);
root->right->left = createNode(6);
root->right->right = createNode(7);
return root;
}
