首先輸入壹個操作，1入隊，2出隊，3退出
如果是1，再輸入壹個將要入隊列的 數據，
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define LEN 1000
int queue[LEN], fir, end;
void printQueue()
{
int i = 0;
for(i = fir; i < end; ++ i)
{
printf("%d ", queue[i]);
}
printf("\n");
}
void insertQueue()
{
int value = 0, i = 0;
printf("Enter the data which you want to insert to queue...\n");
scanf("%d", &value);
queue[end ++] = value;
printQueue();
}
void deleteQueue()
{
printf("after delete the top data!\n");
fir ++;
printQueue();
}
void demo()
{
int Number = 0;
while(1)
{
printf("Enter the number:\n");
printf("1.insert...\n");
printf("2.delete...\n");
printf("3.exit!\n");
scanf("%d", &Number);
if(Number < 1 || Number > 4) return;
switch(Number)
{
case 1: insertQueue(); break;
case 2: deleteQueue(); break;
case 3: exit(0);
default: return;
}
}
}
void creatQueue()
{
int i = 0;
fir = 0, end = 0;
for(i = 0; i < LEN; ++ i)
{
queue[i] = 0;
}
}
int main()
{
creatQueue();
demo();
return 0;
}
