Three engineers: electrical,chemical,software…
they are traveling in a car,when suddenly,the vehicle stops running…
The 3 engineers look at each other,wondering what could be wrong…
The electrical engineer suggest stripping down the electronics of the car,and trying to trace where the fault might have occured..
The chemical engineer suggests that perhaps the fuel has broken down and caused the problem.
The software engineer then offers his suggestion:“Why dont we close all the windows,get out,get back in,and open the windows again???Maybe it will work!”
