Exercise 8.8 using MIN and MAX Functions

[chrisherbert]

Remember, = is for assignment, == is the equality test operator.

Arggh. Not the first time I've been caught out by that! Thanks...

Yeah, mine was basically nested loops as well.  I do have a question, though.

Is there a way to repeat characters to create a string?

For example:

top = '-'*6;

You can't repeat characters in a string, but you can pad output with spaces.  This makes the draw logic a bit simpler:

-(void) draw
{
   int k;
   
   for (k = 0; k < width; k++) printf("_"); printf("\n");
   
   for (k = 0; k < height; k++) printf("|%*s\n",width-1,"|");   // '|' then '|' width-1 spaces away
   
   for (k = 0; k < width; k++) printf("_"); printf("\n");
}

Hi, this is my attempt on the exercise 7.

Code: (Objective-C)

-(void) draw
{
	NSLog (@"Width: %d , Height: %d", self.width, self.height);
	
	// top
	printf(" ");
	for (int i = 0;i < self.width; i++) {
		printf("_");
	}
	
	printf ("\n");
	
	//middle
	for (int i = 0; i < self.height; i++) {
		printf("|");
		
		for (int x = 2; x < self.width + 2; x++) {
			printf(" ");
		}
		
		printf("|\n");
	}
	
	// bottom
	printf(" ");	
	for (int i = 0;i < self.width; i++) {
		printf("-");
	}
	
}

This will draw 10 space block inside for the Rectangle, looks similar to this in xcode console.
