GetTickCount
The GetTickCount function retrieves the number of milliseconds that have elapsed since the system was started. It is limited to the resolution of the system timer. If you need a higher resolution timer, use amultimedia timer or a high-resolution timer.

srand
Sets a random starting point.

看到不懂的函数都不会查MSDN么？
以当前时间（微秒级）作为随机函数的起点（种子）。用来实现像随机的伪随机的。如果不知道什么叫伪随机，请度娘。
