大一上學期C語言課結課課程設計：停車場管理系統
分了學習小組， 我們小組有我、YL（YKL）、MCL
三人分工完成
不過我比較閒所以就把整個項目自己悄咪咪寫完了
題目：
初始：
一小時之內免費
一小時後按每小時五元計費
系統功能
1.車輛入場登記
讀文件中原有內容：車牌號，入場時間
屏幕輸入車牌號，同時寫入文件
入場時間爲當前時間
2.顯示目前場內車輛信息（車牌號、入場時間）和剩餘車位數、已經用的車位數
屏幕輸出
3.管理收費價目表
默認一小時（分鐘）內免費
多於一小時（分鐘）按每小時x元計費
x由屏幕輸入
4.輸入某幾輛車出場時間
更新文件內車輛信息（把出場的車刪掉）
分別輸出結算金額到屏幕
5.統計當天車輛數及收費總金額
輸出到屏幕
6.根據車輛停車總時間從小到大排序
停車總時間爲停車時間到當前時間
輸出排序結果到文件
7.退出系統
數據（自己寫的）
