Threads have 5 states: new State , ready state , running state , blocking state , dead state . The thread pool also has 5 states; However, threads are different from threads, and the 5 states of the line pool are:RUNNING, SHUTDOWN, STOP, tidying,
Problem: All gray codes that produce n bits.
Gray code is a collection of numbers, each of which is represented by a binary, assuming that an n-bit is used to represent each number, and that there is only one bit difference between any two numbers.

Before studying the wait and WAITPID functions, I was puzzled by the use of macro wifexited to check the resulting process termination state: Typically we exit by calling the exit or _exit function in the program. So the terminating state of the
Golden Divide number 0.61803 ... is an irrational number, this constant is very important and will arise in many engineering problems. Sometimes it takes a lot of precision to figure this out.For some precision engineering, the precision of a
Recently, I have been working on Communication Protocol definition and need to use parity bit. I have studied parity and found that there is very little information about C #. I wrote one based on the principle and I will share it with you.

Background:
In programming, many windows or C ++ memory functions do not know the difference, let alone effective use. The root cause is that they do not have a clear understanding of the memory management mechanism of the operating system, this
