1. Waiting for thread to finishWithout waiting for the thread to complete, we need to make sure that the data that the thread accesses is valid until the thread finishes. For example, the thread function holds a pointer or reference to a local

Here is a demonstration of the application of several common operatorsThe difference between the pre-and post-increment operators (note that this is a frequent examination):# include int main (void) {int I, j, K, m;i = j = 3;k = ++i;//After

1. Lvalue ReferenceAn lvalue reference can only bind an lvalue and cannot bind an rvalue.As follows:int x = 1;int &y = x; Bind lvalue, correct int &z = 2; Bind right value 2, compile errorHowever, you can addThe right

There are two ways to terminate a thread in Linux, one is to return from a thread function by calling return, and the second is to call a function#includeVoidpthread_exit (void *retavl);Note: First, if the main thread is returned from the main

Virtual is a very important keyword in the C + + oo mechanism. As long as anyone who has studied C + + knows that a function that adds the virtual keyword to the class base is a dummy function (such as a function print), it is possible to override
