bool judge(vector v1, vector v2) 
{
	bool b = true;
	auto size = (v1.size() > v2.size()) ? v2.size() : v1.size();
	for (size_t i = 0; i != size; i++)
	{
 		if (v1[i] != v2[i])
		{
			b = false;
			break;
		}
	}
	return b;	
}
void test01()
{
	vector v1;
	v1.push_back(2);
	v1.push_back(4);
	v1.push_back(6);

	vectorv2;
	v2.push_back(2);
	v2.push_back(4);
	v2.push_back(6);
	v2.push_back(8);

	vector v3;
	v3.push_back(4);
	v3.push_back(6);
	v3.push_back(8);

	bool b1=judge(v1, v2);
	bool b2 = judge(v3, v2);
	bool b3 = judge(v1, v3);
	cout << b1 << " " << b2 << " " << b3 << endl;

}
int main()
{
	
	test01();
	
	system("pause");
	return 0;
}

完整代码如上。按照题目要求，v1与v2比较返回true，v1与v3、v2与v3都是false。输出结果如下：
