yes, inline functions can be declared in the private section of class. But why would you want it? small functions should be made inline and function defined inside the class are implicitly inline. if you keep inline function private it is must to provide public method (interface) that internally calls inline function.
Consider this:
#include <iostream>
using namespace std;
class PrivateInlinefunction {
int s;
void display();
public:
PrivateInlinefunction()
{
s=9;
}
void demo()
{
display();
}
};
inline void PrivateInlinefunction::show()
{
cout<<s<<endl;
}
int main()
{
Test* t=new Test;
t->demo();
delete t;
t=0;
return 0;
}

Private inline functions are almost never required. But you can make them as private or protected.

suppose A is a base class and B is the derved class. Both have a method foo which is defined as a virtual method in the base class. You have a pointer of classs B and you typecast it to A. Now when you call pointer->foo, which method gets called? The next part of the question is, how does the compiler know which method to call?
