C++细节学习之const对象只能调用const函数

class Oneclass{
public:
void ctfunc() const{}
void uctfunc() {}
}

int onefunc(const Oneclass obj,const Oneclass *pointer,const Oneclass &reference){
obj.uctfunc();        //ok
pointer->uctfunc();   //ok
reference.ctfunc();   //ok

obj.ctfunc();         //error
pointer->ctfunc();    //error
reference.ctfunc();   //error
return 0;
}
