Avoiding dangling pointer errors We can avoid the dangling pointer errors by initialize pointer toNULL, after de-allocating memory, so that pointer will be no longer dangling. AssigningNULLvalue means pointer is not pointing to any memory location. char**strPtr;char*str ="Hello!"; strPtr = &...
to a null pointer. Instead, the pointer inaccurately refers to the memory location of the deallocated memory. The pointer is considered "dangling" since it points to memory that might no longer hold a valid object

In other words: When an object is deleted, pointers to that object do not "magically" become NULL pointers. Instead, the object, that the pointer is pointing to, simply no longer exists. We call this a "dangling" pointer. Printing a "dangling" pointer is perfectly safe. After all, its...
For example, a developer might forget to free up memory after the program no longer needs it, leading to a memory leak that quickly consumes all the availableRAM. Or the developer might free up an object's memory space without modifying a corresponding pointer, resulting in adangling pointerth...
