为什么没有显示字符数据的地址?
class Address { int i ; char b; string c; public: void showMap ( void ) ;};void Address :: showMap ( void ) { cout << "address of int :" << &i << endl ; cout << "address of char :" << &b << endl ; cout << "address of string :" << &c << endl ;}
address of int : something address of char : // nothing, blank area, that is nothing displayed address of string : something
为什么?
... int : something ... char : ... string : something_2
something_2 - something
