Use it in C ++ # Private Members of the define struct class

We know that private members of a class cannot be accessed outside the class.
For example, the following simple class is available:

Class clxecs
{
PRIVATE:
Int iprivate;
};

The following function cannot be compiled:

Void ecs_test ()
{
Clxecs lx;
Lx. iprivate = 13;

Cout <lx. iprivate <Endl;
}

However, there is no way to access the Private Members of the category.
In fact, the method is very simple. Just add the following line of code before the class declaration:

# Define private public

Similarly, this method applies to protecting members:

# Define protected public

However, this is an informal means that will destroy all encapsulation of the class. In C ++, # define also exists to be compatible with C. Therefore, this informal method is used only in special circumstances to protect the private or members of the category.
