C ++ class Example

C ++ class Example
Private means that private members can only be called internally, and Private Members cannot be used outside the class.
Write a simple
Class
{
Public: // you can use public functions to access private members.
Demo () // Private Members can be used here
{M_buff = 0 ;}
Private: // private member
Int m_buff;


}
Void main ()
{
A a; // instantiate an object
A. m_buff = 0; // this operation is not allowed for Private Members due to external access.
A. Demo (); // write the operation on this private member to the inside of the class.
}
