Q7. What is mean by Dangling pointer
Ans. 
A dangling pointer is a pointer that points to a memory location that has been deallocated, leading to undefined behavior.
• Dangling pointers can occur when memory is freed but the pointer is not set to NULL.

• Accessing a dangling pointer can result in crashes or unexpected behavior.

• Example: int *ptr = new int; delete ptr; // ptr is now a dangling pointer
