Thread: Need study help : /

thnx man, i am really going to enjoy the system dependant answer, seriously i cant wait till she marks it wrong.

>>Explain the empty for loop

The counter is declared and initialized outside of the loop condition but referenced in conditional statements within the loop.

Wrong!!
"Empty" refers to the loop body. It just means that all the "action" is inside the parentheses. An example is:

Code:

for( d=2; d < n && n / d != 0; d++ ) ;  // exits loop when d is a divisor of n (or d==n)

Some people prefer this style:

Code:

for( d=2; d < n && n / d != 0; d++ )
     ;

or this:

Code:

for( d=2; d < n && n / d != 0; d++ )
     {};

to make it clear that it's not just a mistake.

Another name for this is a Null Statement.

well i asked bout it today and i posted what she said she wanted.

Code:

int i = 0;

for (; i < 5; i++)
{
cout << "Runs 5 times!" << endl;
}

ya i only listed the ones she actually went over, cs2 sux for us

Well, I don't see how she can call that an empty anything. It's not empty. I see examples like the one I posted and examples like the one golfinguy posted both being called empty loops. They both make sense. I don't see any that look like your teacher's.

But she's marking the test. Too bad. Maybe you can ask her again, & show her our examples, before the test.

Good luck.

Yeah, my empty loop was wrong. I misread what he wanted.

well the test is in a few hours, and thnx to you guys im sure i'll pass it, thank ya.

110 question study guide, TWO questions on the actual test. god i really hate that $$$$$
