What is the dangling pointer? Explain with a proper example.

Solution

A dangling pointer is a pointer which nce pointed to some data, but because of memory deallocation, points to an invalid or null data.

Example:

Suppose we declare and allocate some memory to a pointer:

char *temp = malloc(some_size);

Then we de-allocate the memory allocated to the pointer temp by,
free (temp);

After execution of the above statement, temp becomes a dangling pointer.
