Overriding class methods

[Vasileios Zografos]

Hi, I am trying to override a class method from a child class like the
following:


class ParentClass
{
public:
ParentClass();
virtual ~ParentClass();
virtual double someMethod (int)=0;
}


ParentClass::Pa rentClass()
{
someMethod(1);
}

class childClass::pub lic ParentClass
{
public:
childClass(): ParentClass(){; }
double someMethod(int) ;
}

double childClass::som eMethod(int num)
{
//do something meaningfull here
return 0;
}


int main()
{
childClass cld();
return 0;
}


now, this program will crash because someMethod is called from the
ParentClass constructor.

If someMethod is called outside, e.g.

ParentClass::Pa rentClass()
{

}

and

int main()
{
childClass cld();
cld.someMethod( );
return 0;
}

it will work fine.
However, I want to be able to call the overriden method someMethod()
from the constructor. Is there a way around this problem?

Thank you
Vasileios
