The C + + Standard Template Library provides an auxiliary function-std::thread::hardware_concurrency (), through which we can get the number of threads that the application can actually execute concurrently. In this example, a concurrent version of

In everyday applications, we often use structs or classes to store a piece of information, which is convenient, but not conducive to the transmission of data. For example, in network programming, we need to convert the data in the structure into a
