Hi,

I’ve another query related to member function and member data variables.
Consider below example

Class Hype{
private:
int data;
public:
int get(){return data;}
void set(int d){data=d;}
};
int main()
{
Hype h1,h2,h3;
int a,b,c;
h1.set(10);
h2.set(20);
h3.set(30);
a= h1.get();
b= h2.get();
c= h3.get();
return 1;
}
w.r.t. above example I wanted to ask a weird question.
we are calling functions of class with objects of the class.
But how would the function know where actually the h1.data, h2,data or h3.data is stored in memory?
because internally we are operating upon data-member of that specific object which will have different memory locations for each of them?
So when we call h1.set(10) or h1.get() does the function gets any extra information about the objects location in memory? how?
Can someone pls answer this question?

Thanks
Himanshu
