Traversing an array by different methods.

#include<iostream>
#include<string>
using namespace std;
int main()
{
 int arr[5] = { 2,3,4,5,9 };
 int *p;
 p = arr;
 cout << "Traversing array through the pointer index: " << endl;
 for (int i = 0; i < 5; ++i) {
  cout << *(p + i) << " , ";
 }
 cout << endl << "Traversing Through the pointer : " << endl;
 for (int i = 0; i < 5; ++i) {
  cout << *p << " , ";
  p++;
 }
 cout << endl << "Traversing array using array as pointer : " << endl;
 for (int i = 0; i < 5; ++i) {
  cout << *(arr + i) << " , ";
 }

 cout << endl;
 system("pause");
 return 0;
