6.1.8.Use catch(...) as a default

#include <iostream>

using namespace std;



void f(int val)

{

  try{

    if(val==0) 

       throw val;

    if(val==1) 

       throw 'a';

    if(val==2) 

       throw 123.23;

  }

  catch(int i) {                      // catch an int exception

    cout << "Caught an integer\n";

  }

  catch(...) {                        // catch all other exceptions

    cout << "Caught One!\n";

  }

}



int main()

{

  f(0);

  f(1);

  f(2);



  return 0;

}

Caught an integer
Caught One!
Caught One!
