how to access private data member of class in another class

Question

I

Answer 1

by friend

Answer 2

Simplest way is just add the get and set methods for that particular variable. something like this,

class test
{
private:
int nPrivate;
public:
int getValue ()
{ return nPrivate; }

void setValue (int nValue)
{ nPrivate = nValue; }
};

class tester
{
public:
void AccessPrivate ()
{
test obj;
obj.setValue (65);
cout<<obj.getValue();
}
};

If you want access private method then use "friend" method.

Answer 3

I'd you can, pls use Venkateshs solution. Using the "friend" keyword is less favorable as it gives you direct read *and* write access to all non-const members without a means of copying or preparing the data before it's read / written. Try to use as little access privilege to other classes as possible as the principle of "information hiding" still is *the* mechanism to modularize and decouple software parts.
