程序功能：建立一个单向链表，头指针是list，链表中每个结点包含姓名、基本工资信息，编写del_list函数删除链表中等于某给定基本工资的所有结点。要求在主函数中先建立单向链表（注：当输入基本工资为0时，表示输入结束。），再输入一个给定基本工资，然后调用del_list函数删除链表中等于给定基本工资的所有结点，最后输出删除后的链表信息。用C语言写

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

typedef struct Employee {
char name[20];
int salary;
struct Employee *next;
} Employee;

Employee *createList() {
Employee *list = NULL;
Employee *temp = NULL;
int salary;
printf("Input name and salary of employee (enter 0 to finish):\n");
do {
temp = (Employee *)malloc(sizeof(Employee));
scanf("%s %d", temp->name, &salary);
if (salary == 0) {
free(temp);
break;
}
temp->salary = salary;
temp->next = NULL;
if (list == NULL) {
list = temp;
} else {
Employee *p = list;
while (p->next != NULL) {
p = p->next;
}
p->next = temp;
}
} while (1);
return list;
}

void printList(Employee *list) {
Employee *p = list;
while (p != NULL) {
printf("%s %d\n", p->name, p->salary);
p = p->next;
