今日學習任務 編寫具有定時功能停車場的程式
今日任務完成情況: 課上程式已經基本全部完成,大部分功能都已經實現
今日問題 在停車出車的程式部分還有一些問題,需要明天來修改下!
5個子程式: 第一個檔名: main.c
#include "park.h"
#include <stdio.h>
int main()
{
int choice;
stack park_stack,leave_stack; //停車、讓路棧
queue wait_queue; //等候佇列
welcome();
Init(&park_stack,&leave_stack,&wait_queue); //初始化
while(1)
{
menu();
scanf("%d",&choice);
switch(choice)
{
case 1:
EnterPark(&park_stack,&wait_queue);
break;
case 2:
LeavePark(&park_stack,&leave_stack,&wait_queue);
break;
case 3:
ShowParkInfo(&park_stack);
break;
case 4:
ShowWaitInfo(&wait_queue);
break;
case 5:
bye();
break;
default:
printf("輸入有誤\n");
break;
}
}
return 0;
}
