C++ coding question?

I want to divide a rectange with following definition: four numbers (left, bottom, right, top) so that a rectangle that has the bottom-left vertice of (0,0) and right-top of (4,4) would be defined by the numbers, (0 0 4 4). I need to divide it into four quadrants, but can't work out the code to do this...any suggestions? Or ask if you need clarification ........C++ coding question?
The vertices of the four rectangles can be defined as





(left,bottom),(left+(right-left)/2,bot鈥?br>

(right,top),(left+(right-left)/2,botto鈥?br>

(left,top),(left+(right-left)/2,bottom鈥?br>

(right,bottom),(left+(right-left)/2,bo鈥?br>




Hope this will suffice your need.C++ coding question?
Hope this is what you need.





rectangle has: bottom (b), left (l), right (r), top (t);


quadrant 1 (q1) has: bottom1 (b1), left1 (l1), right1 (r1), top1 (t1);


quadrant 2 (q2) has: bottom2 (b2), left2 (l2), right2 (r2), top2 (t2);


and so on.


We have four quadrants:


q3 q4


q1 q2


where:


b1 = b;


l1 = l;


r1 = (r-l)/2;


t1 = (t-b)/2;





b2 = b1;


l2 = r1;


r2 = r;


t2 = t1;





b3 = t1;


l3 = l1;


r3 = r1;


t3 = t;





b4 = t1;


l4 = r1;


r4 = r;


t4 = t;
