18 Coverage Collection During Simulation

The coordinates for the origin of the moving test rectangle are represented by persistent

data x1 and y1, which are both initialized to -1. For the first sample, x1 and y1 both

increase to 0. From then on, the progression of rectangle arguments during simulation is

as shown in the following graphic.

The fixed rectangle is shown in bold with a lower-left origin of (2,4) and a width and

height of 2. At time t = 0, the first test rectangle has an origin of (0,0) and a width

and height of 2. For each succeeding sample, the origin of the test rectangle increments

by (1,1). The rectangles at sample times t = 2, 3, and 4 intersect with the test
