What is the meaning of “wild pointer” in C?

Question

Can anybody tell me, the meaning of wild pointer in C, how to obtain it and is this available in C++?

Answer 1

To get a wild (aka dangling) pointer you:

• Create an object
• Create a pointer to that object
• Delete the object
• Forget to set the pointer to null

The pointer is now classed as "wild" as it's pointing to an arbitrary piece of memory and using it in this state could cause problems with your program.
