为啥这段代码会CE?

#include<algorithm>
#include<iostream>
#include<cstring>
#include<string>
#include<cstdlib>
#include<cstdio>
#include<cmath>
#include<queue>
#include<vector>
#include<map>
#include<ctime>
using namespace std;
string s[100005];
int main()
{
	int i,j,x=0,y,n;
	cin>>n;
	for(i=1;i<=n;i++)
	{
		getline(cin,s[i]);
		x=max(x,s[i].size());
	}
	for(i=1;i<=n;i++)
	{
		for(j=1;j<=x-s[i].size();j++) cout<<"-";
		cous<<s[i]<<endl; 
	}
}
