When a pointer is not in use, it must be zeroed or nullified by assigning the NULL value, thus preventing indirect access to invalid memory.
What is double pointer in c plus plus?
A double pointer is a pointer which points to another pointer which points to an object.For example:Foobar** foobar = NULL;This means that somewhere in memory, the class foobar has been created. The variable 'foobar' now points to a pointer to that memory. However, in this example, the pointer is created as 0.
