链表之链表的基本操作

链表的基本操作

链表的基本操作包括创建、销毁、插入、删除、查找、打印。这里附上代码：

list.h

typedef struct Node {
    int data;
    Node *next;

} PNode;

typedef struct List{

    Node head;
    Node *last;
} List;

void list_init(List *list);
void list_destroy(List *list);
void list_insert(List *list,int data);
void list_erase(List *list,int data);
Node * list_find(List *list,int data);
void list_print(List *list);
int get_list_max(List *list);
int get_list_count(List *list);
int get_list_min(List *list);

list.c

#include "list.h";
#include <stdio.h>;
#include<stdlib.h>;

void list_init(List *list){

    Node node;
    node.data=0;
    node.next=NULL;
    list->head=node;
    list->last=&list->head;


}


void list_insert(List *list,int data){

    Node *node = (Node*)malloc(sizeof(Node));
    node->data=data;
    node->next=NULL;
    list->last->next=node;
    list->last=node;
    
    

}


void list_print(List *list){
    Node * cur =list->head.next;
    printf("head");
    while(cur!=NULL){
        printf("->[%d]",cur->data);
        cur=cur->next;
    }
    printf("\n");

}

void list_print(Node *p){
    while(p!=NULL){
        printf("->[%d]",p->data);
        p=p->next;
    }
}

void list_erase(List *list, int data){
    Node * pre = &list->head;
    Node * cur =list->head.next;

    while(cur!=NULL){
        if(cur->data==data){
            Node *del = cur;
            pre->next=cur->next;
            free(del);
            cur=pre->next;

        }else{
            pre=cur;
            cur=cur->next;

        }


    }


}

Node * list_find(List *list,int data){

    Node *cur = list->head.next;
    while(cur){

        if(cur->data==data){
            return cur;
        }
        cur=cur->next;
    }
    return NULL;

}

int get_list_max(List *list){

    Node *cur = list->head.next;
    int max=0;
    while(cur){

        if(cur->data>=max){
            max=cur->data;
        }
        cur=cur->next;
    }
    return max;
}

int get_list_min(List *list){

    Node *cur = list->head.next;
    int min;
    if(cur)
        min=cur->data;
    while(cur){

        if(cur->data<=min){
            min=cur->data;
        }
        cur=cur->next;
    }
    return min;
}

int get_list_count(List *list){

    Node *cur = list->head.next;
    int count=0;
    
    while(cur){

        
            count+=cur->data;
        
        cur=cur->next;
    }
    return count;

}

void list_destroy(List *list){
    Node * cur = list->head.next;

    while(cur){
    Node * del= cur;
    cur=cur->next;
    free(del);
    }
    list_init(list);
}
