[c-prog] try catch

[prakashshukla]

#include<iostream.h>
I am experimenting with the following program for error handling. I 
get an error on the word try as "unrecognized word". Pl help

#include<conio.h>
void test(int i)
{
try
{if(i!=0) throw i;
else throw "Zero";}
catch(int a)
{cout<<"Caught an int"<<a<<endl;}
catch(char *s)
{ cout<<"Caught a string"<<s<<endl;}
};
void main()
{
clrscr();
test(1);
test(23);
test(O);
getch();
}
