What is a dangling pointer in embedded C?
A dangling pointer is a pointer that points to a memory location that has been already free-ed by the application and is no longer in use. Sometimes, the programmers fail to initialize the pointer with a valid address; these types of initialized pointers are known as dangling pointers. Dangling pointers occur at the time of the object's destruction when the object is deleted or de-allocated from memory without modifying the pointer's value. If you try to dereference a dangling pointer, it will potentially lead to a runtime error.
