1, traffic light management system principle and analysisFirst understand how it works, because just learn the car, probably understand how traffic lights operate, generally speaking the right turn is the default do not see the lights, you can directly turn right,But sometimes it's different when the traffic has arrows, so we don't think about that. Then the default right turn light is always green. Accordi
implement the system logic. You can use the LOG method to display the program running results. Multiple vehicles will appear on each route. New vehicles should be randomly added on the route, and a car should be reduced every second during the light-green period. Design a road class to represent a route. Each road object represents a route. There are 12 routes in total, that is, a total of 12 road instance objects will be generated in the system. A new vehicle is randomly added to each route an

When you suddenly not on the net, what will you do, you may check whether the router is normal, enter the router access address such as 192.168.1.1, you can log on to the success of the router can confirm that there is no problem. And when you find that the icon in the lower right corner of the desktop turns gray, the X-state, you need to check the interface is good. When checking the cat interface, you need to pay attention to a place that is the cat's indicator light! You may find that the ori

The conditional variable mechanism is not safe for asynchronous signals, that is, calling pthread_cond_signal () or Pthread_cond_broadcast () in a signal processing function is likely to cause a deadlock.

Finally someone put forward the plan, he is so calculate:
1. Suppose 1-1+1-1+...=s
2, then 1-s=1-(1-1+1-1+ ...) ) =1-1+1-1+1...=s
3, so, 1-s=s, apparently, s=0.5
The man was very clever, he knew he could not solve the problem, left the problem to the problem itself, using the contradiction to offset the results. Unfortunately, he finally raised a stupid question, he asked: if the 1 as a t

Today, let's talk about the traffic light system:
First, design a Road class to represent the route. Each Road object represents a route with a total of 12 routes. Therefore, you have to generate 12 Road instance objects.
Then a new vehicle is randomly added to each route and must be added to a collection for storage.
Every second, each route checks whether the lights
