Q1. What is dangling pointer?
Ans. 
A dangling pointer is a pointer that points to a memory location that has been deallocated or freed.
• Dangling pointers can cause crashes or unpredictable behavior.

• They occur when a pointer is not set to NULL after the memory it points to is freed.

• They can also occur when a pointer is used after the memory it points to has been freed.

• Dangling pointers can be avoided by setting pointers to NULL after freeing memory.
