 int main()
 {
 using namespace std;
 const int N = 6;
 string s1[N] = { "buffoon", "thinkers", "for", "heavy", "can", "for" };
 set<string> A(s1, s1 + N);
 ostream_iterator<string, char> out(cout, " ");
 copy(A.begin(), A.end(), out);//buffoon can for heavy thinkers
 return 0;
 }
 
 ostream_iterator<string, char> out(cout, " ");//这句话的string,char分别有什么用吗,我把char去掉好像也可以打印
 
因为你要输出的是string,所以要写string;
 复制代码template <class Type, class CharType = char, class Traits = char_traits <CharType>>
class ostream_iterator;
因为默认就是char,所以去掉也行。 |
