Can anyone do a quick pogram to show me how to handle those

Can anyone do a quick pogram to show me how to handle those 3 exceptions using exception handling in C++?

Task: The Assignment deals with exception handling in C++. Goal: Design and implement a program that reads data from a (product) file and displays content on the screen. The (product) file contains product information with the following attributes:

1) Product ID (database integer ID)

2) Product Name (Maximum 200 character string)

3) Product Price (decimal) 4)

Company Name (Maximum 200 character string)

The file is a tab-delimited and contains 10 rows of product information. The data may contain errors during the load so the program must do the following when loading the data file:

5) If the product ID is not an integer, an \"Illegal ID format\" exception occurs

6) If the product price is not a decimal, an \"Illegal price format\" exception occurs If the program encounters any of these or other exceptions, the following must occur:

7) The program reports the error to the user during the load

8) The program ignores the data record and continues with loading the rest of the file When all records are loaded, a report of the information loaded is presented:

9) Show the counts of records successfully and unsuccessfully loaded

#include <iostream>
#include <fstream>
#include <sstream>
using namespace std;

struct product

   int prodID;
   string prodname;
   float price;
   string companyName;
}*prod[10];

int main()
{
   ifstream infile(\"input_data.txt\");
   string line;
   int counter = 0;
   while(getline(infile, line))
   {
       istringstream iss(line);
       prod[counter] = new product;

       try {
       if(!(iss>>prod[counter]->prodID))
       {
           throw \"Illegal ID format\";
       }
       if(!(iss>>prod[counter]->prodname))

           {

           }
       counter++;
       }catch (const char* msg) {
       cerr << msg << endl;
       }

   }

for(int i=0; i<counter;i++)
{
   cout<<prod[i]->prodID<<\" \"<<prod[i]->prodname<<\" \"<<prod[i]->price<<\" \"<<prod[i]->companyName<<endl;
}
cout<<\"Number of records loaded: \"<<counter<<endl;
}
