reversing the output c++

[pjh-10]

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

int main ()
{
  int i,n;
  int * p;
  cout << "How many numbers would you like to type? ";
  cin >> i;
  p= new (nothrow) int[i];
  if (p == 0)
    cout << "Error: memory could not be allocated";
  else
  {
    for (n=0; n<i; n++)
    {
      cout << "Enter number: ";
      cin >> p[n];
    }
    cout << "You have entered: ";
    for (n=0; n<i; n++)
      cout << p[n] << ", ";
    delete[] p;
  }
  return 0;

for example i want 3 numbers, say the numbers you enter are 1,2,3, it'l will come up ive entered 1,2,3 in that order. i want to know how you reverse that so that it reads what you've typed in,(dynamic memory etc.) then reverses that order. tried about with it but cant get it going? any takers?

Either you insert the numbers in the array in reverse order and print the array normally

 for (n=i-1; n!=-1; n--)
    {
      cout << "Enter number: ";
      cin >> p[n];
    }

or normally insert items in the array, and print them in reverse order

for (n=i-1; n!=-1; n--)
      cout << p[n] << ", ";

did that second method there and its working si far except for one instance, when i do 1,2,3 it comes up 0,3,2,1?

[Lucaci Andrew]

Yeah, well initially was

 for (n=i; n!=-1; n--)

but I edited in

 for (n=i-1; n!=-1; n--)

Was a little bit quick on typewriting, forgot that -1 near the i. Try it now, it will definately work.
