I don't know what you want to do exactely, so I'll correct some things
in your code and write another one that works.

             ^^^^^^^^^^^^^^^^^^^^^
what you are doing here is this:
count will ALLWAYS be <= than 6 because you start at 6 and then
decrease. second, with cycle=6 you ASSIGN 6 to cycle evey loop. I don't
think this is what you want. try cycle <=6 or cycle!=6

you must give the variable to be printed here. something like
printf("The value of count is %d\n",count);
EVERYBODY: even though he doesn't put any variable in the code the
program still prints something that appears to be "cycle" (in the
beginning it's just 6, if you modify cycle=6 in the while it will print
something from 0 to 6.) WHY??

variable-- or variable++ increments it automatically.
you can say var++ or var=var+1, it's the same thing.
that code should be count-- or count=count-1, not count=count--;
the same goes for cycle.

a code that works is this:
#include <stdio.h>

int main()
{
int count;
    count = 6;
    while (count>=0)
    {
        printf("The value of count is %d\n",count);
        count--;
     }
     return 0;
}
