最近做 os 家庭作业，sublime Text3 编辑 c++程序，遇到了输入读不完就退出了运行了。

只是用了指针来实现？求大佬指点小弟。

#include <bits/stdc++.h>
#include <stdio.h>
#include <stdlib.h>
#define mp make_pair
#define fi first
#define se second
#define llt long long 
using namespace std;

char s[10][1100];
const int WORKSIZE=32;
typedef pair<int,int> pii;
pii WorkBlock[WORKSIZE];

int mixnTime;
int startTime=0;
int useSize=0;
struct PBlock{
	int id;
	int priority;
	int time;
	int blocksize;
	struct PBlock* nxt;
};


struct PBlock* readying;

void add(struct PBlock* tmp){
	// 队列为空
	if(readying == NULL){
		readying = tmp;
		return ;
	}

	//队首优先级小于 tmp
	if((readying->priority)<(tmp->priority)){
		tmp->nxt = readying;
		readying = tmp;
		return;
	}

	struct PBlock* pre=readying;
	struct PBlock* suf=pre->nxt;

	//cout<<(pre->priority)<<" ";
	while(suf!=NULL){
		if((suf->priority)<(tmp->priority))
			break;
		pre = suf;
		suf = pre->nxt;
		//cout<<(pre->priority)<<" ";
	}

	tmp->nxt = pre->nxt;
	pre->nxt = tmp;
	//cout<<pre->priority<<endl;
	return ;
}
