What does the following code segment do to the array a[], given that the
current_size variable holds the number of valid elements currently in the array?
for (int i pos + 1; i < current size; i++)
{
}
a[i 1] a[i];
current_size--;
It shifts all the array elements one position to the left (lower index).
It shifts all the array elements one position to the right (higher index).
It removes the element at index pos, while preserving the ordering of all other
elements.
It inserts an element at index pos, while preserving the ordering of all other
elements.
