May 14, 2024 · Dangling Pointer in programming refers to a pointer that doesn’t point to a valid memory location. This usually happens when an object is deleted or deallocated, without modifying the value of the pointer, so it still points to the memory location of the deallocated memory. Example: Dangling Pointer Example.

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.
Dangling Pointer. When a pointer is pointing at the memory address of a variable but after some time that variable is deleted from that memory location while the pointer is still pointing to it, then such a pointer is known as a dangling pointer and this problem is known as the dangling pointer problem. Initially. Later. Example
2 days ago · Types of Pointers in C . Pointers play a crucial role in C Programming by allowing direct memory access and manipulation to make coding even more efficient. Each pointer type has a specific function and use case that enhances the program's capability and flexibility. Here are the types of Pointers in C that you must know: 1) The Null Pointer
