okay all I'm a little rusty on class inheritence here so if you could all refresh my memory please I have the following classes here

the constructor recieves two values an integer and a double so if that is the case how do you build the constructor for the derived class.

here is main

Code:

#include<iostream>
#include <iostream>
#include "Score.h"
void main()
{
numbers p(1, 0);
p.createlist();
cout<<"TRY THIS ON";
}

here is the header

Code:

#ifndef Score
#define Score
#include <fstream>
using namespace std;
// Number *num = new Number(5.3);
class numbers
{
public:
fstream f;
struct node
{
double value;
int type;
node *next;
node *back;
};
numbers(int category, double value )
{ int m=category; //this is your category;
double n=value;//this is your value;
}
void createlist()
{
node* list=NULL;
node *p, *r, *q;
int m;
double n;
f.open("f.txt", ios::in);
while(!f.eof())
{
if(list==NULL)
{
f.seekp(0, ios::beg);
f>>m;
f.seekp(1, ios::cur);
f>>n;
p=new(node);
p->type=m;
p->value=n;
list=p;
p->next=NULL;
p->back=list;
}
else if(list==p)
{
f.seekp(1, ios::cur);
f>>m;
f.seekp(1, ios::cur);
r=new(node);
f>>n;
p->next=r;
r->type=m;
r->value=n;
r->back=p;
r->next=NULL;
p=p->next;
}
else
{
f.seekp(1, ios::cur);
f>>m;
f.seekp(1, ios::cur);
f>>n;
r=new(node);
r->back=p;
r->next=NULL;
p->next=r;
r->value=n;
r->type=m;
p=p->next;
}
}
}
};
class Score : public numbers
{
public:
Score(int a, double b):numbers(int category, double value)
{ int a=category;
double val=value;
}
};
#endif

now I'm a bit rusty so I kind of forgot the correct syntax for linking the constructor for the derived class to the Base class

any advice is welcome here
