actually you should use IF/ELSE, because now the code after the break is what people call "unreachable code".
http://en.wikipedia.org/wiki/Unreachable_code
It's not the true definition but you get the point :P

For small script like your this solution works, but for bigger programs this may cause really really bad headaches when debugging. And I know the feel :D

EDIT: xor is right, your requirements are not very clear.

It's not unreachable code you numpty. That's the worst definition ever.

This is unreachable code.

Code: [Select]

function doSomething( int x )
{
    if (x == 1)
        return 1;
    else
        return 0;

    return 0; // << unreachable, never ever in a million years will this get executed.
}


His print statement gets executed, which means it's not unreachable code.


This is more like what he should be doing:


Code: [Select]
for (int i=0; i < numberArray.length; i++) // Loop through all of the array elements
{
    if ( (numberArray[i] % 2) == 0) // if the current element is divisible by two and has no remainder (an even number)
    {
        if (numberArray[i] < 412) // if the number is less than 412
        {
            print numberArray[i]; // print it out
        }
    }
}


This can also be optimized further by performing the modulo check at the same time as the number size by using an AND operator


Code: [Select]

for (int i=0; i < numberArray.length; i++) // Loop through all of the array elements
{
    if ( ((numberArray[i] % 2) == 0) && numberArray[i] < 412 ) // if the current element is divisible by two and has no remainder
    {                                                          // (an even number)  AND (&&) is less than 412
        print numberArray[i]; // print it out
    }
}

I don't see any ambiguity in the task.

Quote
as soon as your program hits 412 it will stop

That is exactly what it shall do. It says:

Quote
but only up to the number "412" (not including it) Stop there and ignore all numbers past 412 in the sequence

I'm basing it on the assumption that his native language isn't English and the fact that he also said:  (Note there will be numbers over 412.)
