istream_iterator和ostream_iterator的简单使用

#include <iostream>#include <vector>#include <iterator>using namespace std;int main()//少了个void;{ istream_iterator<int> input(cin); int n1,n2; n1 = *input; input++; n2 = *input; cout<<n1<<","<<n2<<endl; ostream_iterator<int> output(cout); *output=n1 + n2; cout<<endl; return 0;}
