What Ooble is saying with loop from i = 12 to 1 means, loop starts at 1, goes until it equals 12, and increments by 1 each time. If you know even a sliver of C, translating that should be no problem.

well here's my code i dnt know what to do nxt, any suggestions thnx in advanvce...

#include <stdio.h>

main()
{

int b;
printf("Enter a value:");
scanf("%d",&b);

for (b=b; b>=1; b--)

{
printf("%d ", b);

}

getch();
clrscr();
}

What you've got to do is stop asking useless questions and actually look at a reference on C.
We're here to help your understanding, but not to do your homework for you. Ooble gave you a perfect description of the algorithm to use. Any inability to complete the assignment at this point is just a lack of effort.

Play around with the code below. I haven't tested or compiled, but just trying to give you an idea of what a nested loop would look like. Also, note that reusing the save variable 'b' that's supposed to be your loop limit as a loop iterator is a bad idea.

(Toggle Plain Text)

#include <stdio.h>

main()
{
int b, i, j;
printf("Enter a value:");
scanf("%d",&b);

for (i=b; i>=1; i--)
{
  for (j = i; j >=1; j--)
  {
    printf("%d ", j);
  }
}

getch();
clrscr();
}

thank you very much for the big help OpenLoop jst added a "printf("\n");" to get the exact output... i++ for you...

here's the code... u've made

#include <stdio.h>
main()
{
int b, i, j;
printf("Enter a value:");
scanf("\n%d",&b);
for (i=b; i>=1; i--)
{

printf("\n"); <------------------------------JST ADDED THIS TO GET THE CORRECT OUTPUT...

for (j = i; j >=1; j--)
{
printf("%d ",j);
}
}
getch();
clrscr();
}

Oh goody. He can Ctrl+V. Any bets on what his first test's mark will be?

Oh joy. Next time, I don't think I'll be helping quite so much.
