shift array left c++ code example

Example 1: c++ shift array to the right

// Shift array elements to right
	const int SIZE = 9;
	int arr[SIZE]={1,2,3,4,5,6,7,8,9};

	int last = arr[SIZE - 1];		
	for (int i = SIZE - 1; i > 0; i--)	
		arr[i] = arr[i - 1];		
	
	arr[0] = last;

Example 2: 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;
