I want to implement hash map, So I want to write a class which will accept object of any class and based on the object size it will return the result.

example:

class A
{
public:
int a;
};

class B
{
char b;
};

my hash map class
??

  • I want a member function which can accept any objects from different class as an argument. – Tuhin Panda Jan 14 '18 at 09:08

    Your design is based on the false premise that a hash function should only take an object's size into account and not its value. – Christian Hackl Jan 14 '18 at 11:48
