Whats wrong with my vector usage?

It prints out the first three names but the program freezes/stop when I resize it. Whats up?

Code:

---

#include <iostream>
#include <string>
#include <vector>

typedef struct _Data
{
 string Name;
 int Age;
}Data;

int main(int argc, char *argv[])
{
 vector<Data> Access(3);
 Access[0].Name= "John";
 Access[1].Name= "Abraham";
 Access[2].Name= "Jamal";
 int i;

 for(i= 0; i< Access.size(); i++)
 {
  Access[i].Age= 14 + i;
 }

 for(i= 0; i< Access.size(); i++)
 {
  cout << Access[i].Name << "\t\t" << Access[i].Age << endl;
 }

 Access.resize(5);
 Access[4].Name= "Sean";
 Access[5].Name= "James";

 for(i= 4; i< Access.size(); i++)
 {
  Access[i].Age= 13 + i;
 }

 for(i= 4; i< Access.size(); i++)
 {
  cout << Access[i].Name << "\t\t" << Access[i].Age << endl;
 }

 cin.get();
 return 0;
}

A vector of size n has addressable elements 0 to n-1.

ok..........anyways, does anyone know why my program stops when it resizes the vector?

It should be stopping just after you resize the vector, when you assign a value to the element with index 5.

When you resize the vector to length 5(that would be n), that means you can address values from 0 to 4 (n-1). But not 5.

ok, I get it now
