    Ok, fine with me (although I don't understand the reason behind it); simply unroll the loop and use four if-statements like this:

    Java Code:
    if (array[0]) count++;
    if (array[1]) count++;
    if (array[2]) count++;
    if (array[3]) count++;
    ... and test the value of 'count' at the end; trying to combine the truth values in the array results in an if-statements with 16 clauses which I find even sillier than the solution above ;-)

    kind regards,

    Jos

    Since it is a course, there are probably a few restrictions on what they can and can't do. When I was stuck in a beginner Python course last year, I was allowed to do whatever I wanted on the assignments for the most part ('cause my teacher was nice), but if the assignment said "solve this using the methods used in class thus far," I wasn't able to use anything more advanced.

    Did your assignment allow you to use an int as counter?
