while (curr_data[1] != (unsigned int)NULL &&
    ((curr_ptr = (void*)curr_data[1]) || 1))

Two part question.

What will (curr_ptr = (void*)curr_data[1]) evaluate to, logically. TRUE?

Also, I know its rather hack-ish, but is the while statement legal C? I would have to go through great contortions to put the assignment elsewhere in the code, so I'd be really nice if I could leave it there, but if it's so egregious that it makes everyone's eyeballs burst into flames, I'll change it.

Is there a better way to write the following conditional in javascript? if ( value == 1 || value == 16 || value =-500 || value = 42.42 || value == 'something' ) { // blah blah blah } I hate having all of those logical ORs strung together. I'm wondering if there is some kind of shorthand. Thanks… >>> More

I know in C like languages logical operators are evaluated one at a time so: false && really_expensive_function() is doesn't result in the function being called (I can't remember the CS name for this). Does the same happen in PL/SQL or do I need to break the IF parts out to separate blocks? >>> More
