Question:What is volatile in C ++ used? (Not reading) Original Discussion link:Http://community.csdn.net/expert/topicview1.asp? Id = 4340502 Forum:Newbie ParkAudit Team:C/C ++ Questioner:IwodgirlReleased:Goodluckyxl Thanks:Codearts,

This test is suitable for candidates of different levels. Most primary-level candidates have poor performance, and experienced programmers should have good performance. In order for you to determine the preference of some questions, no score is

Next: 108 odd tricks for Linux programming-7 (lock-free experiment) This section adds the test_and_set primitive and a complete implementation of the spinlock (refer to nginx spin lock). The main change is that the _ ASM _ ("pause") command is

A variable defined as volatile means that this variable may be unexpectedly changed, so that the compiler will not assume the value of this variable. Precisely, the optimizer must carefully re-read the value of this variable every time when using

The role of the volatile keyword volatile reminds the compiler that the variables defined after it may change at any time. Therefore, each time a compiled program needs to store or read this variable, data is read directly from the variable address.

Although this question is relatively simple, you can still find many problems after careful consideration. Preprocessor) 1. Use the preprocessing command # define to declare a constant to indicate the number of seconds in a year (ignore the leap
