A pointer pointing to a memory location that has been deleted (or freed) is called a dangling pointer. Such a situation can lead to unexpected behavior in the program and also serve as a source of bugs in C programs. o explore pointers in depth and understand how they work with data structures, theC Programming Course Online with Data Structurespro...
Void pointeris a specific pointer type – void * – a pointer that points to some data location in storage, which doesn’t have any specific type. Void refers to the type. Basically, the type of data that it points to can be any. Any pointer type is convertible to a void pointer hence it can point to any value.
NULL Pointeris a pointer that is pointing to nothing(i.e. not pointing to any valid object or memory location). In case, if we don’t have an address to be assigned to a pointer, then we can simply use NULL. NULL is used to represent that there is no valid memory address.
A pointer that has not been initialized to anything (not even NULL) is known as a wild pointer. The pointer may be initialized to a non-NULL garbage value that may not be a valid address.
Jun 4, 2024 · Why is it important to handle Dangling Pointers? Handling dangling pointers is important for maintaining the integrity and stability of a program. If a program attempts to access or modify the memory through a dangling pointer, it can lead to unpredictable behaviour, including crashes and data corruption as shown by the above examples.

Pointers in C are variables that store memory addresses.
A dangling pointer in C indicates a pointer pointing to some deleted/freed location from the program's memory. Here the program’s memory refers to the memory that is presently not in the use of the program. When it comes to dynamic memory allocation, we use calloc (), malloc () functions to allocate a memory block.
