Question

class base{}

class child : public base{

**dummyfunction();**

}

now I am calling a function in which I am passing a child class object.

**child ob;**

function(**ob**);//calling a function  

//function body

function(**base *object**)
{

**//here I want to access the function of child class. How can I do it???**

 **for example dummyfunction()**

}

Answer 1

What you required is downcasting.

you can acheive by making the dummyFunction as virtual in base class and then overriding this function in child class this solution would not require downcasting

otherwise you can use the method described in the below post but this is not safe to downcast
