在C語言中,int
數(shù)組是一種常見的數(shù)據(jù)結(jié)構(gòu),用于存儲整數(shù)值。要將int
數(shù)組與其他數(shù)據(jù)結(jié)構(gòu)進行轉(zhuǎn)換,你需要了解這些數(shù)據(jù)結(jié)構(gòu)的特點以及如何在它們之間進行轉(zhuǎn)換。以下是一些常見的數(shù)據(jù)結(jié)構(gòu)及其與int
數(shù)組之間的轉(zhuǎn)換方法:
char
數(shù)組)將int
數(shù)組轉(zhuǎn)換為字符串:
#include<stdio.h>
#include<string.h>
int main() {
int arr[] = {1, 2, 3, 4, 5};
int n = sizeof(arr) / sizeof(arr[0]);
char str[n * 4 + 1]; // 為每個整數(shù)分配4個字符(包括負號和空格),再加上一個終止符'\0'
for (int i = 0; i < n; i++) {
sprintf(str + i * 4, "%d ", arr[i]);
}
str[n * 4] = '\0'; // 添加終止符
printf("String: %s\n", str);
return 0;
}
struct
定義的鏈表)將int
數(shù)組轉(zhuǎn)換為鏈表:
#include<stdio.h>
#include <stdlib.h>
typedef struct Node {
int data;
struct Node* next;
} Node;
Node* create_node(int data) {
Node* new_node = (Node*)malloc(sizeof(Node));
new_node->data = data;
new_node->next = NULL;
return new_node;
}
Node* array_to_linked_list(int arr[], int n) {
Node* head = create_node(arr[0]);
Node* current = head;
for (int i = 1; i < n; i++) {
current->next = create_node(arr[i]);
current = current->next;
}
return head;
}
void print_linked_list(Node* head) {
Node* current = head;
while (current != NULL) {
printf("%d -> ", current->data);
current = current->next;
}
printf("NULL\n");
}
int main() {
int arr[] = {1, 2, 3, 4, 5};
int n = sizeof(arr) / sizeof(arr[0]);
Node* linked_list = array_to_linked_list(arr, n);
print_linked_list(linked_list);
return 0;
}
struct
定義的二叉樹)將int
數(shù)組轉(zhuǎn)換為二叉搜索樹(BST):
#include<stdio.h>
#include <stdlib.h>
typedef struct TreeNode {
int data;
struct TreeNode* left;
struct TreeNode* right;
} TreeNode;
TreeNode* create_tree_node(int data) {
TreeNode* new_node = (TreeNode*)malloc(sizeof(TreeNode));
new_node->data = data;
new_node->left = NULL;
new_node->right = NULL;
return new_node;
}
TreeNode* insert_into_bst(TreeNode* root, int data) {
if (root == NULL) {
return create_tree_node(data);
}
if (data< root->data) {
root->left = insert_into_bst(root->left, data);
} else {
root->right = insert_into_bst(root->right, data);
}
return root;
}
TreeNode* array_to_bst(int arr[], int n) {
TreeNode* root = NULL;
for (int i = 0; i < n; i++) {
root = insert_into_bst(root, arr[i]);
}
return root;
}
void inorder_traversal(TreeNode* root) {
if (root == NULL) {
return;
}
inorder_traversal(root->left);
printf("%d -> ", root->data);
inorder_traversal(root->right);
}
int main() {
int arr[] = {1, 2, 3, 4, 5};
int n = sizeof(arr) / sizeof(arr[0]);
TreeNode* bst = array_to_bst(arr, n);
inorder_traversal(bst);
printf("NULL\n");
return 0;
}
這些示例展示了如何將int
數(shù)組轉(zhuǎn)換為其他數(shù)據(jù)結(jié)構(gòu)。請注意,這些示例僅用于演示目的,實際應(yīng)用中可能需要根據(jù)具體需求進行調(diào)整。
