Thread: how to handle exceptions

hi...i m learning the concepts of exception handling and trying to run my first program using try- catch block.
the problem is the compiler is not able to identify try and catch keywords.
is there a problem in the compiler or do i have to include any special header file for it.??
plz guide me...the code is as follows:

Code:

#include<iostream.h>
#include<conio.h>
void  main()
{ 
  int a,b;
  cin>>a>>b; 
  int x=a-b;
  try
     {  
       if(x!=0) cout<<“Result (a/x)”<<a/x<<“\n”;
       else throw(x); 
     } 
  catch (int i) 
    {
        cout<< “Exception caught”<<i<<“\n”;
    }
   cout<<“End”;
   getch();
}
