C 链表如何删除节点

如何解决C 链表如何删除节点

所以我修复了“字符串名称”的问题，现在我想 添加一个通过其 ID 删除节点的函数，所以我尝试创建一个函数来定位具有请求 ID 的节点，但进展不顺利，因为它没有跟踪我输入的 ID。 完整代码如下：

#include <stdlib.h>
#include <stdio.h>

typedef struct stringData {

    int id;
    char *name;
    int payment;

    struct stringData *next;
} Node;

Node *addEmployee(int id,char *name,int payment) {
    Node *newNode = (Node *)malloc(sizeof(Node));
    newNode->id = id;
    newNode->name = strdup(name);
    newNode->payment = payment;
    newNode->next = NULL;
    return newNode;
}


void insert(Node **link,Node *newNode) {
    newNode->next = *link;
    *link = newNode;
}

void removeEmployee(Node *head,int id){
    while (head != NULL){
            head = head->next;
        if(head ->id == id){
            printf("The employee exists.");
        }
        printf("The employee does not exists.");
    }
}


void printList(Node *head) {
    while (head != NULL) {
        printf("----------------------------------\n");
        printf("Name: %s\n",head->name);
        printf("ID: %d\n",head->id);
        printf("Payment: %d\n",head->payment);
        printf("----------------------------------\n");
        head = head->next;
    }
}



int main(void)
{
    int id;
    char name[42];
    int payment;
    int input;

    Node *head = NULL;
    Node *tail = NULL;
    Node *n;


    n = addEmployee(1,"Dor",5000);
    insert(&head,n);
    tail = n;
    n = addEmployee(2,"David",10000);
    insert(&head,n);
    tail = n;


    printList(head);

    removeEmployee(head,2);



    while((input != 4)){
        printf("\nPlease select 1 option:\n1) Add an employee - type 1\n2) Remove an employee - type 2\n3) Show a list of employees - type 3\n4) Exit - type 4\n");
        scanf("%d",&input);
    switch(input){
    case 1:
        printf("\nPlease enter the employee's id: ");
        scanf("%d",&id);
        printf("\nPlease enter the employee's name: ");
        scanf("%41s",name);
        printf("\nPlease enter the employee's payment: ");
        scanf("%d",&payment);

        n = addEmployee(id,name,payment);
        insert(&head,n);
        tail = n;
        break;

    case 2:
        printf("Please enter the ID of the employee you would like to remove: ");
        scanf("%d",&id);
        break;

    case 3:
        printList(head);
        break;

    case 4:
        printf("Good-bye");
        break;

    default:
        printf("This is not an option!");
        break;
        }
    }

    return 0;
}

我不知道如何进入它，我对这个主题不是很熟悉，所以看看一些例子会很有帮助。
