General - Changing table content 1st with last - - help request

Hi,
i am trying to make program which will:

a) ask for table size
b) change order from last to 1st
c) change 1st with last.

a) & b) are ok but with c) it is printing only A+1 instead of starting from A[0] can anyone help with it, what part of this code is wrong?

Code:
    #include <iostream>
    #include <cstdlib>

    using namespace std;

    int main ()
    {
       //create table
       int n;

       //table size
       cout<<"How many elements in table"<<endl;
       cin>>n;
       int A[n];

       //storing elements

       cout<<"You can type"<<n<<" elements."<<endl;
       for(int i=0;i<n;i++)
       {
          cin>>A[i];
       }
       //display input elements
       for(int i=0;i<n;i++)
       {
          cout<<"table elements "<<"A["<<i<<"]: "<<A[i]<<endl;
       }
          //display from last to 1st
          cout<<"Displaying from last i"<<endl;

       for(int i=n-1;i>=0;i--)
          {
             cout<<"values in table "<<"A["<<i<<"]: "<<A[i]<<endl;
          }
       //changing 1st with last element of table
          cout<<"changing value of 1st with last"<<endl;

       for(int i=n-1;i>0;i--)
             {
                int box =A[n-1];
                A[i]=A[i-1];
                A[0]=box;
                cout<<"table elements "<<"A["<<i<<"]: "<<A[i]<<endl;
             }
       return 0;
    }
