What kind of strings? If they're std::string objects then they're not pointers and cannot be compared to nullptr.

I need to limit user to input empty string or null. How can I do that in C++?
example string A="abcd"
string B= null
Is there any way how to write this?

There is no way to set a string NULL because it is not a pointer. You can use the clear member function maybe?
