Friend class - private member variable

[hairobinson]

How do we access the private member variable outside the class with out using friend ?

How do we access the private member variable outside the class with out using friend ?

via get() and set() methods?

via get() and set() methods?

Or just by definig any function in the class, so it will have access to the private member:

class exple{
int i;
public:
(...)
int fct(int x){x=i;cout<<x;}
};
 

Or something like that

You can try something like this,

class X
{
    int i;
 
public:
    X():i(10){};
 
    int* fn()
    {
        return &i;
    }
};
 
void main()
{
    X x;
    int* pI = x.fn();
    cout << *pI;
 
 
}

Thanks guys for the response

Of course, providing access to the private member breaks encapsulation. That means you can no longer rely on the member functions to protect the values in the data member. So, if the value get screwed up your list of suspects exopands from just the member functions to all the function in program that can touch that data member directly or indirectly.
