The difference between NULL and nullptr in c++

NULL is 0 in C++. This is because the void* type in C++ is not allowed to be implicitly converted to other types. So before, 0 was used to represent a null pointer in C++, but in the case of overloaded shaping, the above will appear. The problem. Therefore, C++11 has added nullptr, which can guarantee that it represents a null pointer in any case without the above situation. Therefore, it is recommended to use nullptr instead of NULL in the future, and NULL be used as 0.
