Pointer to a vector

[Scythe37]

I am trying to make a pointer to a vector in order to be able to easily choose from a few different vectors for a non recursive towers of hanoi homework assignment I have. I have been looking all of the internet and trying to find a syntax that works, but so far the closest thing I have gives me an error that I cannot convert a vector pointer to a vector pointer.

Can anyone tell me what the proper syntax is or if it's even possible to do what I want to do?

Thanks in advance

Your question is not exact. What do you mean by "pointer to a vector"?

Something like this?

typedef vector <int> ints_t;
ints_t* i_am_a_pointer_to_a_vector;

[Scythe37]

something like

vector<int> A, B, C;
vector<int>::pointer X = A

I want to be able to make X equal to any one of the first vectors.

Wait... then you mean a pointer to an element in a vector?

No, I want the X to be able to access any element in the other vectors.

Please pay attention. You cannot learn anything unless you actually try some of the suggestions we give you.

#include <iostream>
#include <vector>
using namespace std;

void print( vector <int> * v )
  {
  for (unsigned n = 0; n < v->size(); n++)
    cout << v->at( n ) << " ";
  cout << endl;
  }

int main()
  {
  int _primes[]     = { 2, 3, 5, 7 };
  int _fibonaccis[] = { 1, 1, 2, 3 };

  vector <int> primes(     _primes,     _primes     + 4 );
  vector <int> fibonaccis( _fibonaccis, _fibonaccis + 4 );

  print( &primes );
  print( &fibonaccis );

  return 0;
  }

Hope this helps.
