C语言实现队列

#include<stdio.h>#include<string.h>int queue[10000],l,r;void push(int x)//入队列{queue[r++]=x;}int pop(int x)//出队列{return queue[l++];}int main(){l=0;r=0;int m,n;while(scanf("%d",&n)!=EOF){    while(n--)    {        int x;        scanf("%d",&m);        push(x);    }    scanf("%d",&m);    while(m--)    {if(l>=r)    break;    int x    printf("%d\n",pop());    }}    return 0;}
