ahh i can't figure out this loop

**blindleaf** · 03-18-2003

ok i have a loop that will make a diamond, i can't get the freaking dimensions right, i dontk now what to change, i've been fiddlin around with the variables but can't figure out what to change by how much, can anyone help? heres the code:

Code:

//top of diamond or pyramid
			for (row = 1; row <= height1 - (height1/2); row++)
			{
				for (space = height1; space >= row; space--)
					printf(" ");
				for (col = 1; col <= (row * 2 - 1); col++)
					printf("*");
				printf("\n");
			}
			//bottom of diamond
			for (row = 1; row <= height1 - 1; row++)
			{
				for (space = 1; space <= row + 1; space++)
					printf(" ");
				for (col = 1; col <= height1 * 2 - (row * 2 + 1); col++)
					printf("*");
				printf("\n");
               }

and that makes a diamond with height 5 that looks like:

Code:

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

but i need one with height 5 that looks like:

Code:

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

can anyone help? i know this may sound stupid but i've gone trhough and i just can't figure this out.

It appears as if you were trying to be too clever with your loops, try something like this:

Code:

#include <stdio.h>

int main ( void )
{
  int space;
  int height1 = 5;
  int row, col;

  //top of diamond or pyramid
  for (row = 1; row <= (height1/2 + 1); row++)
  {
    for (space = height1; space >= row; space--)
      printf(" ");
    for (col = 1; col <= (row * 2 - 1); col++)
      printf("*");
    printf("\n");
  }

  //bottom of diamond
  for (row = height1 / 2; row >= 1; row--)
  {
    for (space = height1; space >= row; space--)
      printf(" ");
    for (col = 1; col <= (row * 2 - 1); col++)
      printf("*");
    printf("\n");
  }
  
  return 0;
}
