I found something weird.


Why nothing output ? I think it should display "index=1".

Any help ?

Thanks.

In the for loop, the boolean condition evaluates to false on the first try (when i is zero) because dddd does not contain "0". Therefore, the loop body never executes, and i is never incremented to 1.
