Arrays question

[Jose94ji]

This is what I have so far but I was suppose to use a dynamic array not a normal one. How would I go about changing this to a dynamic array?

 #include <iostream>

using namespace std;
int main()
{
 const int arraySize = 25;
 const int patternSize = 10;

 int arr1[arraySize] = {0,1,2,3,4,5,6,7,8,9};
 for(int i=0; i<arraySize; i++)
 {	 
	 cout << arr1[i%patternSize] << " ";

 }
	

	system("PAUSE");
	return 0;
}

Syntax for "dynamic array": <type> <identifier>=new <type>[array size]
