In QT Project project (I use Qt5.6), to use pointer pointers, I need to include header file # # <memory>, do not write wrong # # # <memory.h> This is two different files, If written in the latter case, a string in namespace Std does not name a type is present. In addition to C++11 support also depends on the compiler, if you can use the project nullptr, then the basic judgment of your compiler support C++11.
