Good work, Rakesh Ranjan. I like your code. As for zhshqzyc's code, while I do dislike the techniques being used, I don't find the code to as alien as everyone is indicating. I see two items that violate Ansi C: the // style one line comments and the use of "const int max =20;" instead of "#define max 20". Both of these are legal in C++. But also there is a new C standard out called C99. I don't have access to a C99 compiler, but I strongly suspect that the code is legal C99. And for the record, gcc accepts the code as well. When I run the code, it more or less works for me. I also dislike the output format and will never regard output a 2 dimensional array as a column "correct". The coding techniques being used invite the programmer to confuse rows and columns and that is what happened here. I used square matrices to avoid any problems.

Compiling the code on a compiler that does not understand the one line comment style results in a lot of errors. This is because a comment like:
//******
has the beginning of a old c style comment starting with the second character. The compiler has a very hard time recovering from that error. If your C compilers are freaking out, I think that is the principal reason. Even gcc with an -ansi switch gave up, no -pedantic switch needed.

       or margins (in the CSS sense, one being inside the bounding box, the other being outside)

SYNOPSIS

	 use Graphics::Primitive::Insets;

	 my $insets = Graphics::Primitive::Insets->new({
	   top	   => 5,
	   bottom  => 5,
	   left    => 5,
	   right   => 5
	 });

METHODS

   Constructor
       new Creates a new Graphics::Primitive::Insets.

   Instance Methods
       as_array
	   Return these insets as an array in the form of top, right, bottom and left.

       bottom
	   Set/Get the inset from the bottom.

       equal_to
	   Determine if these Insets are equal to another.

       left
	   Set/Get the inset from the left.

       right
	   Set/Get the inset from the right.
