What kind of error occurs if I tried to compile and run the following code (with line numbering):

L1 int * a_ids = new int[4]; // should be same as malloc making 4 numbers

L2 delete a_ids; // should be same as free(a_ids)

L3 a_ids = NULL;

Question 3 options:

	Syntax error (line L2): delete a_ids should be delete[] a_ids on line L2.
	Memory access violation (line L3): Can't set the array after deleted
	NULL pointer exception (line L3)
	Syntax error (line L1): "int* a_ids" should be "int a_ids" since it is an array.
