I need help passing conditional values to a base constructor.

Hi everyone,

Can someone tell me how can I pass conditional values to a base constructor?

let say I have

Code:

---

class Base{

Base(int a, int b, int c){
}

};

class Derived :public Base{
Derived(int x, int y, int z){
}

}

I want if x=0;
Derived(x,y,z) :Base(x,y,z){
}
if x>0
Derived(x,y,z) :Base(x+2,y+2,z+2){
}

You can easily create a private member function (although, to be sure, you could make it static since the object hasn't been constructed yet).
Pass along whatever parameters you need in your decisions to it, then have it return an appropriate value and initialize with it.
Eg:

Code:

---

Derived(int x, int y, int z): Base(myfunc(x), myfunc2(x), myfunc3(x)) {}
static int Derived::myfunc(int x) { /* Do something */ }
//...

---

thank you!
