C++中 vector结合迭代器实现增删操作！

1 说明：目的是为了将vector里 符合isdel==true的元素删掉。

2 实现代码

#include "stdafx.h"
#include <assert.h>
#include <time.h>
#include <ObjectArray.h>

using namespace std;

class Test
{
public:
	Test(bool isdel)
	{
		this->is_delete=isdel;
	}
	bool is_delete;
};

void print(vector <Test> &v)
{
	std::vector<Test >::iterator iter;
	for(iter=v.begin();iter!=v.end();++iter)
	{
		cout<<(*iter).is_delete<<" ";
		assert(!(*iter).is_delete);
	}
	cout<<endl;
}

void add(vector <Test> &v,bool b)
{
	Test *t= new Test(b);
	v.push_back(*t);
	delete t;
	cout<<endl;
}

void vec_del(vector <Test> &v)
{
	std::vector<Test >::iterator iter;
	for(iter=v.begin();iter!=v.end();)
	{
		if((*iter).is_delete==true)
		{
			iter=v.erase(iter);
		}
		else
		{
			++iter;
		}
	}
}

int _tmain(int argc, _TCHAR* argv[])
{
	vector <Test > svec;
	std::vector<Test >::iterator iter;
	srand(time(NULL));

	cout<<"随机赋值:"<<endl;

	for(int i=0;i<100;++i)
	{
		int value=rand()%2;
		add(svec,value);

		cout<<"i="<<i<<" T/F: "<<svec.at(i).is_delete<<endl;
	}
	cout<<endl<<"删除 true:"<<endl;
	vec_del(svec);
	print(svec);
	cout<<endl;
	
	system("pause");
	return 0;
}
