Can we call private functions?

[Rehan FASTian]

What I think is that we will invoke a public function which will invoke a private function of class. Any other way?

Why to make private function?

[MiiNiPaa]

To call something which isn't meant to be called by user, but widely used by methods of class.
Example: reallocate() function in container classes.

[maeriden]

Friends of a class can access its private members.

[Rehan FASTian]

So there is no other way to utilize private function except through public function or friend function?

[MiiNiPaa]

Or other private function.

[Rehan FASTian]

How the other private function will be envoked?

[MiiNiPaa]

By public functions, protected functions, friend functions, friend classes...
I gave you an example of function ( reallocate() ) you shouldn't ever give users access to, but which can be called by many public function: for example: reserve(), push_back(), shrink_to_fit()...
