Can someone help me with this problem?
write a program that prints the following diamond shape. you may use output statements that print either a single asterisk ( * ) or a single blank. maximize your use of repetition (with nested FOR structures) and minimize the number of output statements...
Code:*
* * *
* * * * *
* * * * * * *
* * * * *
* * *
*
That's a triangle, not a diamond. You can pass on your homework assignment by answering just that.
sorry

there u go!!
Ah... teacher almost fooled ya. Didn't they?
The answer you can find here: http://cboard.cprogramming.com/annou...t.php?f=3&a=39
yeah my gf should read that...thanx man!!
I've never known a Triangle to have 4 sides, I am astounded by this new feat.Quote:

The original post was edited, bumfluff.

You missed the thread before a moderator added code tags to preserve formatting. This is how it was displayed originally:

So, where are the four sides? ;)
Bumfluff obviously sees geometry in more than three dimentions, allowing him to conclude that a triangle has four sides.
What does it mean? What tags? When moderators will add them?Quote:

psychopath - what a stupid thing to say!! He sees in 4-D! The triangle obviously evolved over time to become the great and powerful diamond we see today!
Ok, I'm going to copy the diamond and post it (the one from the first post):
*
* * *
* * * * *
* * * * * * *
* * * * *
* * *
*
Now I'm going to do the same, but wrap CODE tags around it:
Same again with Quote tags:Code:*
* * *
* * * * *
* * * * * * *
* * * * *
* * *
*
The code tags allows as many spaces as you desire, however, without them, the multiple spaces are deleted. Quote tags put the fancy grey background to it, but don't preserve the formatting as the code ones do.Quote:

I hope this is what you were looking for and helps. Let me know if you don't understand my comments. I am sure it isn't the most elegant and efficient, but I am pretty sure that it works. Has variables that easily allow you to control the height, width, and starting spot.
Code:#include <iostream>
using namespace std;
int main()
{
//rows for the height
//cols for the width
const int rows = 3;
const int cols = 20;
//the column you want to position the uppermost point on the screen
int startingSpot = 5;
//increment over every row
for(int i = 0; i < rows +1; i++)
{
//increment over every column of every row
for(int j = 0; j < cols; j++)
{
//if you are in the correct range
//notice that the number of asterisks on any line is a function
//of the line number you are on. Basically you print out an asterisk
//at the startingSpot of hte first line. Then the next line you print
//an asterisk out at the startingSpot and then an asterisk offset by
//1 in front of and behind. This is the i variable that tells you
//which row you are one
if(j > startingSpot - i and j < startingSpot +i)
cout<<"*";
else
cout<<" ";
cout<<" ";
}
//print out a blank line and start on the next row
cout<<endl;
}
//this does the same thing as the above code, but it prints the rows in reverse
for(int i = rows +1; i >0 ; i--)
{
for(int j = 0; j < cols; j++)
{
if(j > startingSpot - i and j < startingSpot +i)
cout<<"* ";
else
cout<<" ";
}
cout<<endl;
}
cin.ignore();
cin.get();
}
... and this is why they say the internet is a good learning medium and every kid should have a computer to help with school.
... and why my daughter still learns from text books
>I am sure it isn't the most elegant and efficient
At least it's decent code. Most people who try to give free lunches can't even get hello world right.
>but I am pretty sure that it works
I'm torn between telling you it's broken and telling you to verify that it works. A good programmer has no doubts because a good programmer tests her code thoroughly before releasing it. On the other hand, if I tell you it's broken, the OP may not try to steal your code for an easy good grade. That's why we don't give out homework answers.
What a sexist you are, assuming that a good programmer would be a "her" :)Quote:

The reason I said "but I am pretty sure that it works" is because I tested it with a few numbers and it gave me the correct results so I couldn't find anything wrong with it, but I didn't exhaustively check for errors. Such as what if they enter too few columns such that for the given number of rows it trims off part of the diamond? I suppose I could check for more errors, but it's really not that important to me for this little program.
>What a sexist you are, assuming that a good programmer would be a "her" :)
I'm not sexist. I'm egotistical. :)
Well, probably a little sexist too, now that I think about it. ;)
A good programmer is a master programmer. One filled with Tao. That lives within the Tao. He, is the Tao and the Tao is he.
... consequently, a good programmer is an it.
*bows*
>... consequently, a good programmer is an it.
A good programmer may be an it, but that sounds too much like objectifying programmers, which can only be bad. How about being a great programmer? A great programmer is nothing because nothing is everything and a great programmer knows everything, so by knowing everything a great programmer ends up being everything and to become everything you must be nothing. So to become a great programmer you need...um...you need to...uhhh...not be a programmer at all? Drat! Now I've gone and confused myself.
As you were.
Some are born great.
Some have greatness thrust upon them.
Some accidentally discover greatness, then run away from it.
One thing a programmer is not...a philosopher
or into them.Quote:

I can't decide if you said something profound or dirty. I've been around you guys too long it seems. ;)
Daoist theory attempts to explain greatness.
To be great is to go on;
to go on is to go far;
to go far is to return.
Therefore you can be great as long as you keep trying and succeed in doing that. I'm positive, when applied to programming, the last line has something to do with "going back to basics" in order to fully understand something more complex.
But this is of course my own boring interpretation. Thinking is hard!
>But this is of course my own boring interpretation.
That's the problem. It sounds good but nobody really knows what it means. I wonder how many philosophers were clinically insane. :p
I believe this fulfills all the requirements:
edit: oh, hello c++ board, thought I was on the c one.Code:#include <stdio.h>
int main(void)
{
int i, j;
char *diamond[8] = { " *\n",
" * * *\n",
" * * * * *\n",
"* * * * * * *\n",
" * * * * *\n",
" * * *\n",
" *\n", NULL };
for (i = 0; diamond[i] != NULL; i++) {
for (j = 0; diamond[i][j] != '\0'; j++) {
printf("%c", diamond[i][j]);
}
}
return 0;
}
All of them. Just like the mathematicians.Quote:

Well if mathmeticians are as insane as philosophers, then math is mostly truth but partly insane as it is the product of insane people. ...Math wasn't that bad until India invented algebra and made mathematics completely abstract. Making the real unreal is DEFINITELY crazy.
Since a diamond is a rhombus and a rhombus is a shape, and shapes are geometry which is also math, we can talk about insanity and technically be on topic.
:D That was awesome to type.
However this is the C++ forum, therefore objects and things that are object-oriented are good. :)Quote:

it's two triangles, just do the opposite for the top that you did for the bottom.
