Delete NULL but no compile error
c++, null
Solution
The C++ language guarantees that delete p will do nothing if p is equal to NULL.

Problem
I'm confused why the following C++ code can compile. Why does a call to delete the method of 0 not produce any error?! ``` int *arr = NULL; // or if I use 0, it's the same thing delete arr; ``` I did try to run it, and it did not give me any error at all...
