STL:vector中如何使用at()来避免程序报错

#include <iostream>

#include <vector>

using namespace std;

int main()
{

	vector<int> Vec;

	for (int i = 0; i < 30; i++)
	{

		Vec.push_back(i);

		//cout << Vec.size() << endl;
		//cout << Vec.capacity() << endl;
		//cout <<  endl;
	}

	//使用at()处理越界的问题
	for (int i = 0; i < Vec.size()+2; i++)
	{
		try
		{
			//
