Thread: [Help]Correct or Wrong?Loops

I have asked to write a program using for loops to create a hollow box but my code is

Code:

Is this acceptable? I left a few days before I have to pass up my assignment. Anyone please help?

To use for loops to do this, you need two of them:

Code:

#include <stdio.h>
#include <stdlib.h>

/* function main begins program execution */
int main ()

{
  int height; /* initialize height */
  int width;  /* define width */
  int high;   /* define high */
  int wide;   /* define wide */
  int n;        /* define n */

  printf("\n\n Enter the height and width [3-40]: "); /* prints "Enter the height and width:" */
  scanf("%d", &n); /* scans the height and width of the box */

  height = width = n;
  printf("\n\n");

  if ((width < 3) || (width > 40)) 
  { 
	printf("An error has occur.\n"); /* prints "An error has occur." */
	exit (1); /* exit program if has error */
  }


  for(high = 0; high < height; high++)  {
    printf("\n");
    for(wide = 0; wide < width; wide++) { 
      if(high == 0 || high == height-1)
        printf("*");   
      else { 
        if(wide == 0 || wide == width - 1)
          printf("*");
        else
          printf(" ");
      }
    }
  }


   return 0; /* indicate program ended successfully */
} /* end function main */

That might help.

Help me, it says my error has illegal use of else without matching if, I am newbie to for statement, anyone help me plz? I am desperate :|

your still missing the main point..here check the scanf statement and printfstatement

Code:

	printf("Enter the height and the width\n");
	scanf("%d", &n);

	height = n;
	width = n;

chk der...for example if you type..." 30 21" ..look the scanf statement will read only 30

and will put height and width as 30...
in order to correct it... try

Code:

int x;
	printf("Enter the height and the width\n");
	scanf("%d %d", &x,&n);

	height = n;
	width = x;

@ Adak THX(edited)

Means that I have to enter 1 time which is the value of n to determine both of its height and width. Eg, I enter 5, it prints both 5 height and width. But what Adak wrote, I have to enter 2 different numbers to get different height and width. Eg, I enter 5 6, it prints 5 height and 6 width. Unless I misinterpret the question wrongly. Else if Adak mind to change the code abit so that when I enter 1 value it equals to both height and width?
