Chapter One: Hello the concurrent world of C + +1. What is concurrencyThe simplest and most basic concurrency is the simultaneous movement of two or more independent activities of two or more.For a single processing unit or core, the machine can only perform one task at a time, not enough that it can switch tasks more than once per second. This is called task switching.2. The Concurrency pathway2.1 Multi-processIndependent processes can pass messages

In C ++, the left value (lvalue) is the amount of addresses that can be obtained. Because it often appears on the left of the value assignment statement, it is called the left value. For example, a variable with a name. For example: Int a = 10; // a is a left value. Traditional C ++ references are left-value references. For example, int ra = a; associates ra with. This is the left value reference. C ++ 11 introduces the concept of right value referen

ICMP protocolIP does not provide a reliable transport service, nor does it provide end-to-end or point-to-point acknowledgement, which is implemented in the IP module if an error can be seen through the ICMP report.
