For loops help

Dear everyone,

Can someone please help me on my HW. I'm trying to write a program
that will display the following:

*
***
*****
*******
*********
*********
*******
*****
***
*

I'm having a hard time writing a code for this one. I tried several
times, but I can't get it to work properly. I live in Japan and I take
an online C++ course. The instructor lives in the US so whenever I am
awake, he's asleep. Therefore, I cannot contact him directly when I
need help. I have to get this program up and running ASAP. I tried
searching everywhere for help, but there's none except for this group.
My textbook isn't much of a help either. I WILL GREATLY APPRECIATE THE
HELP I WILL GET!

Post some of the attempts you have made. Nobody will just give you the
solution. Also, read the link below, especially where it talks about
(or links to) how a homework question should be asked:

http://www.clc-wiki.net/wiki/Introduction_to_comp.lang.c

I can offer one solution, though I doubt that's what you're looking
for:

#include <stdio.h>

int main(void)
{
int i;

for (i=0; i<1; i++)
{
printf(" *\n");
printf(" ***\n");
printf(" *****\n");
printf(" *******\n");
printf("*********\n");
printf("*********\n");
printf(" *******\n");
printf(" *****\n");
printf(" ***\n");
printf(" *\n");
}

return 0;
}

Then a. you want to replace <stdio.h> with something like <cstdio.h++>;
b. you want something like stdout << instead of puts(; and c. you need
to ask in comp.lang.c++, not comp.lang.c.

They don't have e-mail in the US? Gosh. I knew that country was a bit
primitive in some aspects, but that's truly backwards.
I have to get this program up and running ASAP.

I really, really doubt that.

FWIW: DYODH. HTH; HAND.

Post your best attempt. We'll fix your code, but we won't write it

Resolve to do it in two parts, the asterisks are growing or the asterisks
are shrinking.

For the growing asterisks:
Write two functions, one to print n spaces and another to print n asterisks.
Call these functions with the appropriate parameters, and have the main loop
provide the end of line. That is, one iteration of the for loop prints one
*line*.

Make a table like this:

line nbr nbr asterisks
1 1
2 3
3 5
4 6

Note the sequence and provide appropriate code in the for loop to provide
the appropriate value to the asterisk printing function.

Note well how the liberal use of functions empties the mind of extraneous
non-interesting (at the moment) things.

Now do the shrinking asterisks bit.

Done.

OK, let's un-obfuscate this a little bit:

------
int putchar(int);

int main(void)
{
int z;

for (z =
002354l / 000644l / 000132l / 000322l / 000374l; z < 000132l;
putchar(z % 011 + z / 011 > 002354l / 000644l
&& z % 011 + z / 011 < 002354l / 000132l
&& z / 011 < z % 011 + 002354l / 000322l
&& z / 011 > z % 011 - 002354l / 000374l ? '*' : ' '),
z % 011 - 011 + 1 || putchar('\n'), z++);
putchar('\n');
return 002354l / 000644l / 000132l / 000322l / 000374l;
}
------

Ho do you come up with stuff like this? I don't get it. My mind doesn't
work that way.

Puzzled,

Well, I see no point using two loops when one will do, that's all.

I also don't think a program is sufficiently obfuscated if its workings are
immediately clear to the reader after running the source through cpp and
indent!

It normally shows, and is in the usenet article. The only place it
should be suppressed is in a reply to my article. If your reader
doesn't show it on a normal read, something is wrong with your

Looked quite alright for me, strangely enough (KNode on SUSE). Usenet

True, but the interesting thing is that it /does/ show in every single
post you make, with the exception of the one that I replied to.
Perhaps my ISP's news server flaked out or something.

That is odd. The sig definitely showed up when I read the article.
