After graduating five years has been a muddle, with Juleta a year, the eldest brother brought me too much wisdom on the knowledge on the help, the boss Northern people character good cool, responsive. At the beginning of the course is to find a job, in the video of the eldest brother also told some of his life experience, slowly found that the work is not the end, how to cultivate and find their own interests through continuous learning, enrich themse

Const qualifier1. Use const to give literal constants a name (identifier), which is called an identifier constant, because the declaration and usage of an identifier constant is much like a variable, so it is also called a constant variable2. General form of definition:(1) const data type constant name = constant value;(2) Data type const constant name = constant value;3. For example: const float pi=3.14159f;4. Precautions:(1) Constant variables must be initialized at the time of definition;(2)
"fake"? As mentioned earlier, the "/dev/random", CryptGenRandom () generation is slow and consumes more performance. In cases where the unpredictability of random numbers is low, the pseudo-random number algorithm can be used, because the performance is relatively high. True random number generators are used when the unpredictability of random numbers is high, and the hardware devices of true random number generators need to consider the cost problem, while "/dev/random" and CryptGenRandom () h
BOOL TypeC + + new type, representing logical true and false1. The logical type is also called the Boolean type, its value is true (logical true) and False (logical false), the number of bytes stored in the different compilation system may differ, VC + + 1 bytes.2. Declaration method: Boolresult;result=true;3. Can be used as integers (true is generally 1,false to 0)4. When converting other types of values to Boolean values, non-0 values are converted to true, and 0 values are converted to falsec
I always believe that for a beginner, the technical trend in the IT field cannot catch up with and cannot catch up with it. I often see my DDMM throwing away textbooks and selling expensive big numbers such as C # and VB. Net, which makes me very sad. However, I think it is funny to have a lot of discussions about the usage of pointers in C.

Haha, it's good. Everything exce
not be different in each execution. So how can we use software to generate seemingly uncertain random numbers?
There are many algorithms used to generate random numbers. The simplest and most commonly used method is the linear same-remainder method: the number of n + 1 = (number of n * 29 + 37) % 1000, here, % is the "evaluate the remainder" operator. Many people like me have a headache when they see formulas. I will explain it in code. MyRand is a c

code may also lock the object. This can result in a deadlock, where two or more threads wait to release the same object. For the same reason, locking public data types (compared to objects) can also cause problems. and lock (this) is only valid for the current object, if the synchronization effect is not achieved between multiple objects. Lock (typeof (Class)) is too wide to be the same as a locked string.SummarizeThe introduction of lock is here, there are a few points to note1. Lock is an obj
