Since the inner loop declares $i again, it should mask the outer loop's $i as per other languages. Besides being useful, it makes more sense.

No, that's not true. You don't redeclare ANYTHING here... you're just using the same variable $i, just like you would do in C.

//In the following example, the inner loop 'i' masks the outer loop 'i': int array[] = {1, 2, 3, 4, 5}; for (int i = 0; i < 5; i++) {

        int num = array[i];
        printf("%d", num);
        for (int i = 0; i < 5; i++)
                printf("%d", i * num);

}

Otherwise, the declaratory statement in the second loop is completely meaningless.

You don't declare anything... Derick -- "Interpreting what the GPL actually means is a job best left to those
