How do I specify the constructor definition of the inherited class?

I have a base class (header):

class BaseClass
{
    public:
        BaseClass(int); // note no default constructor.
}

and a class that derives it:

class DerivedClass : public BaseClass
{
    public:
        DerivedClass(void);
}

DerivedClass::DerivedClass (void) // note SPECIFICALLY no parameters.
{
    super (10); // equivalent of what I am trying to do in Java (I think)
}

How do I call the constructor of the inherited class in my derived class?

class BaseClass 
{ 
    public: 
        BaseClass(int) {};
} ;
class DerivedClass : public BaseClass 
{ 
    public: 
        DerivedClass(void); 
}; 

DerivedClass::DerivedClass (void)
:BaseClass(10)
{ 

}

This is what you want:

DerivedClass(void):BaseClass(10) {
    //blah blah blah
}

like this:

DerivedClass::DerivedClass (void) : BaseClass(10) 
{ }

NOTE: if you are unfamiliar with the syntax, look out for member initialization list.
