Therefore if we want a parent thread to be detached from the child, then we can use this detach function. In C++, once the thread is detached or uses the detach() function, then we cannot stop such threads, and
you can organize tasks in a hierarchy. For example, a parent task can create new children tasks. This can create a dependency, so that canceling a parent task also cancels its child tasks.

问题原因其实很简单,就是没有对这个数组进行初始化操作,即当前只存在数组的声明,系统只为二维数组对象的引用变量分配了空间,并没有创建相应的数组对象 。那么在相关的方法中,自然无法对这个看似存在但实际却找不到影儿的数组进行操作,所以就会报错了。 解决办法 在类中再添加一个成员方法init(),给这个对象数组进行内...

We take a thread as the behavior of a sequential deterministic program under execution and multi-threading as the form of concurrency provided by contemporary programming languages such as Java and C#. We outline an algebraic theory about threads and multi-threading. In the case of multi-threading...
several tools and frameworks facilitate tlp management, offering features to simplify thread creation and synchronization. popular languages like java and c++ provide built-in libraries such as java's java.util.concurrent package and c++'s standard library threads. additionally, parallel programming ...
