C++读取字符串数据的两种方式

对于同样的样例输入：

ladder came tape soon leader acme RIDE lone Dreis peat
ScAlE orb eye Rides dealer NotE derail LaCeS DrIed
noel dire Disk mace Rob dries

方式1

#define LOCAL
#include<iostream>
using namespace std;
int main(){
    #ifdef LOCAL
    freopen("data.in","r",stdin);
    freopen("data.out","w",stdout);
    #endif

    string s;
    while(cin>>s){
        cout<<s<<endl;
    }
}

样例输出
