volatile keywordVolatile is the simplest method of synchronization, and of course, it's a price to pay. It can only be synchronized at the variable level, the meaning of volatile is to tell the processor, do not put me into the working memory,

1. What is a data structureIn general, when using a computer to solve a specific problem, there are a few steps to follow:① abstract A proper mathematical model from the specific problem;② design an algorithm for solving the mathematical model;③

has always been a simple time_t t,time (&t), CTime (&t) to represent time, and later to take time as the name of the log file, it is a little forced. Learn a bit.TM structure: struct tm{int tm_sec; /* seconds – The value interval is [0,59] */ int

There is no systematic study of C + +, so the use of the work is particularly awkward, nor will not, nor do not understand, but read the code and write code always a little rusty feeling. So the supplement is still to fill up, now think about the

ASSERT preprocessing macrosAssert is a preprocessing macro, so-called preprocessing is actually a preprocessing variable that behaves like an inline function, and an Assert macro uses an expression as its condition:ASSERT (expr)The first is to

Introduction to Generics:C#2.0 the introduction of generic mechanism, it realizes the parameterization of the type and method, that is, the type becomes the logical reuse of the parameters, and a large number of type security checks are transferred
