#include <iostream>
#include <string>
using namespace std;using namespace std;
class foo
{
int value;
public:
int showRecord(void);
foo(int x) :value(x){}
};
int foo::showRecord(void){ cout << value; return value; }
int main()
{
int(foo::*pt[1])(void) = {& foo::showRecord }; //array with pointers to member functions
foo *da = new foo(15);
(da->*pt[0])(); //same as da->showRecord
delete da;
cin.ignore();
return 0;
}

}
