C++ stringstream的用法

   

1、从流中获取字符串

#include"iostream"#include"sstream"using namespace std;int main(){string s,goal;getline(cin,s);stringstream  ss(s);while(ss>>goal)   cout<<goal<<endl;return 0;}

2、从流中获取数字

#include"iostream"#include"sstream"using namespace std;int main(){string s,goal;int x;getline(cin,s);stringstream  ss(s);while(ss>>x)   cout<<x<<endl;return 0;}

3、从流中获取字符

#include"iostream"#include"sstream"using namespace std;int main(){string s,goal;int x;char y;getline(cin,s);stringstream  ss(s);while(ss>>y)   cout<<y<<endl;return 0;}
