public: 
	int f(int a){return x*a;} 
protected: 
	int getX(){return x;} 
private:  
	int x;

are u calling it in main or in the implementation file

anonymous · Answer

Int getX needs to be public. not protected.

nethwa · Answer

The protected-flag only allows the Object itself and its following generations (classes, which extend this class, inheritance) to access the method. I'm not familiar with C (i guess its C) but for me it looks like thats your problem.
Change it to public and it maybe it'll work.

if any data member or  member function is declared  protected they will be accessible  only in the class itself and the inherited  class .Further  accessibility will  depend on the type of inheritance i.e public ,private etc..
To sort this out just  make int getX() function  public .
I suppose that the function cout<<objC.getX();  is written in the main() or in a member function after creating  objC .

the value of getx is protected  in this program there is  parameters x is used to pass the value of x but the value of x is private so main cannot execute it he  should change it public
