If is not hard, but be careful of the boundary condition. 
But I got stuck at how to determin the size of array? If using the pointer (*p )which pointing the head of the array as the input, how do we compute the size of the array?

Hussein · Answer

To find the size of an array without passing it.. you can do it using templates in C++.

template 
void p(int (&arr)[N]) {
	cout << N << endl;
}

int main() {
	int arr[10];	
	p(arr);
}
