One sweltering day, I was scooping ice cream into cones and told my four children they could "buy" a cone from me for a hug. Almost immediately, the kids lined up to make their purchases. The three youngest each gave me a quick hug, grabbed their cones and raced back outside. But when my teenage son at the end of the line finally got his turn to "buy" his ice cream, he gave me two hugs. "Keep the changes," he said with a smile.

表示linux和windows的编译环境不一样，
在dev里格式错误但到了noi里满分，，，，
这就比较尴尬了，，

#include<iostream>
using namespace std;
string kong;
string a[1001];//保存每个单词 
int tot=1;//行数 
int main()
{
    int n;
    cin>>n;
    for(int i=1;i<=n;i++)
    {
        cin>>a[i];
        a[i]=a[i]+' ';
    }
    string ans;
    for(int i=1;i<=n;i++)
    {
        if((ans.length()+a[i].length()-2)>=80)
        {
            if(ans.empty()==true)
            continue;
            cout<<ans;
            cout<<endl;
            ans=kong;
            ans=ans+a[i];
            tot++;
        }
        else
        {
            ans=ans+a[i];
        }
    }
    cout<<ans;
    return 0;
}
