PostPosted: Fri Feb 06, 2004 7:39 pm   Post subject: correction plz

i was wonderin if anyone could help in by correcting my code.... i am doin a program with will print out the following diamond pattern

y*****
*******
y*****
yy***
yyy* (the y is a space)

the thing is the middlw line the bolded line ... .. if the user inputs the size 5 (it should lok like the pic) themiddle line is always +2 ... mine gives an extra so it gives like 8 stars .... and i am able to remove sumof the lines above ....

import java.awt.*;
import hsa.Console;
public class Star
{
static Console c;
public static void main (String [] args)
{
int n = 0;
int size = 0;
int space = 0, star = 1;
Console c = new Console ();

c.println ("Please enter an odd number from the range of
1-25");
n = c.readInt ();
space = n / 2;
star = n / 2;
while (space != 0)
{
for (int i = 0 ; i < space ; i++)
c.print (" ");
for (int i = 0 ; i < star ; i++)
c.print ("*");
for (int i = 0 ; i < space ; i++)
c.print (" ");
space--;
star = star +2;
c.print ("\n");
}

for (int i = 0 ; i < star ; i++);
c.print ("*"); //middle
line
for (int i = 0 ; i < star ; i++)
c.print ("*");
c.print ("\n");

while (star > 1)
{
space++;
star = star - 2;
for (int i = 0 ; i < space ; i++)
c.print (" ");
for (int i = 0 ; i < star ; i++)
c.print ("*");
for (int i = 0 ; i < space ; i++)
c.print (" ");
c.print ("\n");
}
}

I tried to help, but I couldn't run the program, cause
code:

import hsa.Console;

I can't seem to import this, is this a standard thing that comes with JDK?
Im a noob, and I run java out of MS Dos prompt so...
I probably could help you a bit if I could run it and see what its like.

            space--;
            star = star + 2;
            c.print ("\n");
        }

        for (int i = 1 ; i < star ; i++);
        c.print ("*");
        for (int i = 1 ; i < star ; i++) //midle line
            c.print ("*");
        c.print ("\n");
        while (star > 1)
        {
            space++;
            star = star - 2;
            for (int i = 0 ; i < space ; i++)
                c.print (" ");
            for (int i = 0 ; i < star ; i++)
                c.print ("*");
            for (int i = 0 ; i < space ; i++)
                c.print (" ");
            c.print ("\n");
        }

    }
}


Mod edit: use the [ code ] tags, makes it easier to read

Help you with what and why did you post here in this thread?

well.. i've posted this before in some other thread.. but anyways..:

the for-loop draws out the lower part of the diamond. if u reverse the algorithm (which i haven't done) u can possibly create the upper part similarly

code:

int w = 9;     // width of diamond

print    repeat " "  by  w - ((w - 2) mod w);  // might have to replace these
print    repeat "*"  by  (w - 2) * 2;          // three lines with better code
println;                                       //

for (int i = w - 1; i >= 0; i--) {
    print    repeat  " "  by   w - (i mod w);
    print    repeat  "*"  by   i * 2;
    println;
}


PS: note this is not valid java code.. just pseudocode. but you should be able to make sense of it
