vector的itrerator支持random access

#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<int>intVector;
intVector.push_back();
intVector.push_back();
intVector.push_back();
intVector.push_back();
intVector.push_back();
intVector.push_back(); vector<int>::iterator p1 = intVector.begin();
for (; p1 != intVector.end(); p1++)
{
cout << *p1 <<" " <<&p1<<endl;
}
//cout <<endl<< "the last" << *p1 << endl; // vector iterator is not dereferencable
cout <<endl<< &p1 <<endl;
cout << *(--p1) << " "<<&p1<<endl;// cout << *(p1 - ) <<" "<<&p1<< endl;
cout << p1[-] << " "<<&p1<<endl;
cout << *p1 << " " << &p1<< endl;
*p1 = ;
cout << *p1 << " " << &p1 << endl;
for (; p1 != intVector.end(); p1++)
{
cout << *p1 << " " << &p1 << endl;
}
cout << endl << endl;
for (p1=intVector.begin(); p1 != intVector.end(); p1++)
{
cout << *p1 << " " << &p1 << endl;
}
cin.get();
return ;
}
