STL算法之copy

 copy(beg, end, dest) //dest表示输入迭代器

#include <iostream>  
#include <algorithm>  
#include <vector>  
using namespace std;

int main()
{
	int myints[] = { 10, 20, 30, 40, 50, 60, 70 };
	vector<int> myvector;
	vector<int>::iterator it;

	myvector.resize(7);   // 为容器myvector分配空间  

	copy(myints, myints + 7, myvector.begin());
	cout << "myvector contains: ";
	for (it = myvector.begin(); it != myvector.end(); ++it)
		cout << " " << *it;
	cout << endl;

	copy(myints + 1, myints + 7, myints);
	cout << "myints contains: ";
	for (size_t i = 0; i < 7; ++i)
		cout << " " << myints[i];
	cout << endl;

	return 0;
}

输出结果
