C语言实现联赛球队管理系统

1、C语言实现联赛球队管理系统/*联赛球队管理系统*/该系统实现功能为联赛各只球队积分榜的更改、排名，可输入比赛结果，自动录入积分榜#include <stdio.h>#include <conio.h>#include <malloc.h>#include <string.h>#include <stdlib.h>#include <windows.h>#define N sizeof(struct team_information)void introduction ();/ 对本管理系统的介绍void print_tit

2、le ();/ 打印开头和星号void load_menu ();/登陆菜单void load ();/登录void post ();/ 新用户注册void print_headmenu ();/ 打印主菜单void show_league ();/ 读取联赛积分榜struct team_information *creat_league ();/ 创建联赛球队积分表total_score (int, int);/计算总积分void print_score ();void ABOUT ();/ 版权说明int exit_system ();/ 退出程序void choice1 ();/ 返回退

3、出选项void choice2 (struct team_information *);/ 增删减查选项void league (struct team_information *);/ 排序、创建积分榜void add_team ();/ 增加球队void renew ();/ 更新数据信息struct team_informationchar name20;int winning;int level;int losing;int score;int pos;struct team_information *next;void main()introduction (); print_tit
