C++ 算法 中的 copy函数

template<class InputIterator, class OutputIterator>OutputIterator copy(InputIterator first, InputIterator last, OutputIterator result);

#include<iostream>
#include<algorithm>
#include<vector>
int main()
{
	int newints[]={15,25,35,45,55,65,75};
	std::vector<int> newvector(7);
	std::copy (newints, newints+7, newvector.begin());
	std::cout <<"newvector contains:";
	for (std::vector<int>::iterator ti= newvector.begin(); ti!=newvector.end(); ++ti)
	std::cout<<" " <<*ti;
	std::cout<<"\n";
	return 0;
}
