What is dangling pointer in C?

by
  • If a pointer is pointing any memory location, but meanwhile another pointer deletes the memory occupied by the first pointer while the first pointer still points to that memory location, the first pointer will be known as a dangling pointer. This problem is known as a dangling pointer problem.
  • Dangling pointer arises when an object is deleted without modifying the value of the pointer. The pointer points to the deallocated memory.
