Namespaces are commonly structured as hierarchies to allow reuse of names in different contexts.As an analogy, consider a system ofnaming of peoplewhere each person has a given name, as well as a family name shared with their relatives.If the first names of family members are unique only with...

some best practices for handling errors in your code include checking return values from functions carefully, using descriptive variable names so it's clear what each piece of data represents, logging all relevant information about an error (including stack traces if possible), and testing thoroughly...
述代码中的线程类 std::thread 是标准库自带的线程类,在C++11中开始提供。 用这个类创建的线程对象的时候,必须提供一个函数(或者仿函数functor)作为线程执行体。所以,一个线程其实就是一个独立执行的函数。独立于main线程。 thread1对象在构造的时候,接受一个普通的C函数作为执行体。
