What should we assign to a C++ pointer: A Null or 0?
In C++, Null is defined as 0. Null or 0 is an integer.
In case of a pointer, we can assign a pointer p as −
Float* p = NULL; Float* p = 0; Float* p = nullptr;
3 of them will produce the same result. null ptr is a keyword introduced in C++11 as a replacement to NULL.
