While loop that displays no negative numbers

[Savage]

We can you use do-while also...
Can you show me that way also???

Offcourse,it would be like:

int n;

do{
       //cin number


}while(n<0);//No need for those if-else statments at all

whenever i try to use your code i get a runtime error saying that n has not been defined

And how did u exactly implemented my code?

PS:Post just do-while loop or while which u have used.

well when i put the while in it say i, n have not been defined
but with the dowhile it just says n have not been defined

[nirJianWu]

int i = 0;

cout<< "Please enter a number" << endl;
cin >> i;

while(i == 0)
{
if(i>0)
esle
}

ur, it will print nothing...

in your code, the code inside while loop will be executed only when i ==0 .

A while loop that doesn't display negative numbers:

for(;;) cout << 42;

But in my code n is defined:

int n;

Post that part here.

Yes offcourse.

He,he.

Good one Jos ;-)

How about this:

forever(;;) cout <<42;

for(;;) cout << 42;

Strictly speaking that is a for loop not a while loop, when I saw this post I had

while(1)
    ;

in mind. The point these posts Greatness is that your original question (specification) is so loose (poorly specified) that many many constructs will fit what you have said although most of them are unlikely to do anything close to what you want.

When you post your next question please try to be a little more precise.
