undefined symbol try

[sows]

#include<iostream.h>
#include<conio.h>
void test(int x)
{
   try
   {
              if(x>0)
                 throw x;
        else
                 throw 'x';
   }
 
   catch(int x)
   {
              cout<<"Catch a integer and that integer is:"<<x;
   }
 
   catch(char x)
   {
              cout<<"Catch a character and that character is:"<<x;
   }
}
 
void main()
{
   clrscr();
   cout<<"Testing multiple catches\n:";
   test(10);
   test(0);
   getch();
} 

I also tried by removing .h in header files but still it shows error message
undefined symbol try

What compiler are you using, does it support the C++ exception mechanism?

I ask because you are using the non-standard header iostream.h which has been depricated since 1998. Early non-standard compilers did not necessarily support the C++ exception mechanism (try / catch)

Also be sure that exception hsndling has been turned on in your compiler. Visual C++ requires a switch setting to activate the exception handling.
