std shift elements in array 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;
