c++ 11 shift right vector code example

Example: shift array elements to left c++

int temp=arr[0];
	/********************************	Method 1
	for (int i = 0; i < SIZE - 1; i++)		
	{
		arr[i] = arr[i + 1];
	}
	arr[SIZE-1]=temp;
	*/
	//									Method 2
	for (int i = 1; i < SIZE - 1; i++)
	{
		arr[i - 1] = arr[i];
	}
	arr[SIZE - 1] = temp;
	for (int i = 0; i < SIZE; i++)
		cout << arr[i] << "\t";
	cout << endl;
