you seem to have a lot of undeclared identifiers.
could you post a complete code?

This needs fixing:
--------8<--------
{
     istream operator>>(istream &in, Inventory &item);
--------8<--------

You probably want:
--------8<--------
istream operator>>(istream &in, Inventory &item)
{
--------8<--------

You are missing operator<< too.

Hi redice

I have compiled your code and corrected several errors (marked with error here)

I have one error left which is almost at the end of the code

setPriceTo9s is undefined, I'm not sure what you meant.

Here's the corrected code..........

#include <iostream.h>
#include <conio.h>
   
class Inventory
{
    friend ostream& operator<<(ostream &out, const Inventory &itm);
    friend istream& operator>>(istream &in, Inventory &itm);

private:
    int stockNum;
    int quantity;
    double price;
};

ostream& operator<<(ostream &out, const Inventory &itm)
{
    out<<"Stock number "<<itm.stockNum <<"Quantity "<<itm.quantity<<"Price "<<itm.price;
    return(out);
}

istream& operator>>(istream &in, Inventory &itm)
{    
     
    cout<<"Enter Stock number:" << endl;  // Error here
    cin>>itm.stockNum;
    cout<<"Enter Quantity    :" << endl;  // Error here
    cin>>itm.quantity;
    cout<<"Enter Price       :" << endl;  // Error here
    cin>>itm.price;

    if(itm.stockNum < 0||itm.stockNum>999)
   
     throw("Stock Number out of range ");   // Error here

    if(itm.quantity < 0)
   
          throw(itm.quantity);
   
     if(itm.price > 100.00)
   
          throw(itm.price);
   
     return(in);
}

//--------------------------------------------------------------------
void main()
{
    const num=5;
    Inventory anItem[num];
    int x;
    for(x=0;x<num;++x);   // Error here
    {
    try
    {
         cin>>anItem[x];   // Error here
    }
    catch (const int quantity)
    {
    cout<<quantity<<" is a negative quantity-that's O.K."<<endl;  // Error here
    }
    catch (const char *msg)
    {
    cout<<msg<<endl;
    cout<<"Please re-enter"<<endl;
    --x;
    }
    catch (const double pr)
    {
    cout<<"The price "<<pr<< "is too high"<<endl;
    anItem[x].setPriceTo9s();                // Error still here: Dont know what setPriceTo9s is
    cout<<"Price summary "<<endl;
    getch();
}

Hope it helps
