本篇内容介绍了“如何用C语言链表实现工资管理系统”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！
题目：建立工资管理系统，对职工工资的相关信息进行管理。职工工资相关信息包括职工工号，职工姓名，月份，每月工资和年度总工资等，具体要求如下;
1、建立该系统的存储结构
2、录入职工某个月的工资
3、查找某个职工某个月的工资
4、修改某个职工某个月的工资
5、删除每个职工的工资相关信息
6、统计某个职工年度总工资
7、对职工的月工资或年度总工资进行排名
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
typedef struct worker

char name[40]; //姓名
int month[12]; //月份
float gz[12]; //月工资
float total; //年度总工资
struct worker *next; //指向下一节点的指针
} Worker;
//相关的函数声明
Worker *CreateList(Worker *L, int n); //根据输入的职工人数，批量创建节点
void DeleteList(Worker *L, char n[]); //删除节点
void LIstSearch(Worker *L, char n[]); //查找职工工资信息
void InsertInfo(Worker *L); //插入职工工资信息
void SearchMonthSalary(Worker *L, char n[], int m); //查找某个职工的某个月的工资
void Input(Worker *p, int i); //为节点的数据域赋值
void Print(Worker *L); //输出整个链表的数据
void Modify(Worker *L, char n[], int m, float s); //修改某个职工的工资
void menu(); //工资管理系统的菜单
