There is another way to initialize it, which is used for arrays and structs, but in c++98, it can also be used for single-valued variables:int hamburgers={24};The case for using curly brace initializers for single-valued variables is not much, but

In C + +, the passing of member function pointers as arguments to other functions and normal function pointers is different, firstLet's review the method of passing normal function pointers://----------------------------------------------------------
