初识STL中的copy函数

#include <iostream>#include <algorithm>#include <vector>#include<iterator>//ostream_iterator 在<iterator>头文件的定义中using namespace std;int main () {  int myints[]={10,20,30,40,50,60,70};  vector<int> myvector;  myvector.resize(7);     //将数值复制到vector里，参数依次是开始、结束，myvector数组的开始  copy (myints, myints+7, myvector.begin() );  cout << "myvector contains:\n";  //将数值复制到输出流中，参数依次是开始、结束，输出流  copy(myvector.begin(), myvector.end(), ostream_iterator<int>(cout, " "));  cout << endl;  return 0;}
