T Minus loops

[CRooky]

(while)

T minus 10 and counting
T minus 9 and counting
T minus 8 and counting
T minus 7 and counting
T minus 6 and counting
T minus 5 and counting
T minus 4 and counting
T minus 3 and counting
T minus 2 and counting
T minus 1 and counting

Declare the following index before the while loop:

int index = 10;

Correctly code a while statement below using the variable index as defined above, to produce the output shown above.


So this is what my code looks like...can anyone give me a hint about what I'm missing..?? I also have to convert this same loop into a do while and for loop. So if I can get this one right I think the others should come relatively easy.
Thanks Everyone...! (:

while (int index >= 10)
      {
         cout << "T minus " << index;
         index--;
      }

pay attention to the emphasized words.

it should also be while it is greater than 0. Otherwise it will only do 10 and 9.

I would just use a for loop though.

for(int i = 10; i > 0; --i)
{
    std::cout << "T minus " << i << " and counting" << std::endl;
}

thanks giblit but can I use this same format in a while loop...?? or how do they differ really...? Cuz my professor wants me to write both versions of it..

You can do what you just had, though slightly different (as @ne555 suggested):

int index = 10;
while (index) { // same thing
    std::cout << "T minus " << index-- << " and counting\n";
}

Though, really should be using index > 0, but just showing that this does work.
