赋值操作

函数原型:

代码语言:javascript复制
#include<iostream>
using namespace std;
#include<deque>
//deque的赋值操作
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.尾插赋值
	deque<int>d1;
	d1.push_back(5);
	d1.push_back(2);
	d1.push_back(0);
	p(d1);
	//2.operator=赋值
	deque<int> d2;
	d2 = d1;
	p(d2);
	//3.assign赋值
	deque<int> d3;
	d3.assign(d2.begin(), d2.end());
	p(d3);
	//4.assign赋值
	deque<int> d4;
	d4.assign(5, 521);
	p(d4);
}
int main()
{
	realApply();
	system("pause");
	return 0;
}
