    }
    else{
    	cout<<"Product of "<<a<<" and  "<<b<<" is: "<<a*b<<endl;
    }
}
 
int main()
{
    try
    {
    	try
            {			
        	    func(5,-1);
	    }
	   catch(int b)
            {
		if(b==0)
			throw "value of b is zero\n";
		else
			throw "value of b is less than zero\n";
	}
    }
