There are two ways to access it. 1) Friend functions can access the private data of the class. 2) Typecast the object address to a pointer and then access the individual variables through memory access. Below example explains this in detail. class Test { private: int a; char b; }; void somefunc () { Test obj; int *x; char *y; // x points to member variable 'a' after below call. x = (int *) &obj; // y points to member variable 'b' after below call. y = (char *)(x + 1); *x = 3; *y = '='; } This method is however not recommended. The ideal method is to use public member functions for all operations on class object. read less

Assessing the Private Member without Member Function or Friend Function is possible in C++. But it is little tricky. This is not known to many of the programmers. But such private member accessing needs some tweeks in the class.

In C++ there is a function called friend function, which allow us to access the private data of the class, A friend function of a class is defined outside that class' scope but it has the right to access all private and protected members of the class.

It is not possible to access private members of a class without its own member function. That is the main reason why it is set as private so that members of other class should not be able to directly access private member of the class.

Using friend function you can access the private data of a class through object. The other way is you can get the address of the object. From this address, you can traverse the variable based on the size and get the value of the variable. But this will void the OOPs concept. Example Class Student...

Private data can be accessed in only members functions. Even if you create a object you cannot access the private data.
