deque容器01之构造函数

#include<iostream>

//deque的构造函数
void p(const deque<int>& d)
{
	for (deque<int>::const_iterator it = d.begin(); it != d.end(); it++)
	{
		//*it = 100; 加了const关键字后，就无法对数据进行修改
		cout << *it << " ";
  }
	cout << endl;
}
void realApply()
{
	//1.默认构造
	deque<int>d1;
	d1.push_back(5);
	d1.push_back(2);
	d1.push_back(0);
	p(d1);
	//2.区间
	deque<int> d2(d1.begin(), d1.end());
	p(d2);
	//3.n个elem拷贝给本身
	deque<int> d3(1, 521);
	p(d3);
	//4.拷贝构造
	deque<int> d4(d3);
	p(d4);
}

	realApply();
