call constructor from base class

[mwebel]

Hi ikind of remember this being easy but cant find it on google:
i have a base class and a derived class.
The base class has two constructors normal and int overloaded one.
thing is i want the derived class to call the constructors for the base
class using also the same kind of overloading. like this:

class BASE{
public:
BASE();
BASE(int x);
}

class DERIVED : BASE{
//normal constructor
DERIVED(){
//init BASE with normal constructor
};
//overloaded constructor
DERIVED(int){
//init BASE with overloaded constructor
};
}

int main(){

//this should call the overloaded constructor of BASE!!!
DERIVED dummy(3);
return 1;
}

it would be my death if the wrong base constructor would be called or
even called twice...
thanks for any help!

Just put the proper base constructor call in your derived class'
initialization list. See below.

class BASE{
Don't use all caps for your names. Reserve that for macros only (and
use those only sparingly!).
public:
BASE();
BASE(int x);
}

class DERIVED : BASE{
//normal constructor
DERIVED() : BASE() // Would be called by default anyway {
//init BASE with normal constructor
};
//overloaded constructor
DERIVED(int i) : BASE( i ) {
//init BASE with overloaded constructor
};
}

int main(){

//this should call the overloaded constructor of BASE!!!
DERIVED dummy(3);
It will!!!
return 1;
}
