  • Answer: For c++ thread safe singleton class design for multi threaded environment, we need to synchronize the function that creates and returns singleton object. We will see the singleton class design without synchronization and with synchronization applying on function that create singleton object in C++
  • People use singleton everywhere. Read some threads recently from stackoverflow that singleton should be avoided in C++, but not clear why is that. Some might worry about memory leak with undeleted
  • The problem is unrelated to the concept of static member or singleton pattern. The problem is the problem of multithreading, the shared data, more exactly, access to the shared objects, and is solved via the mutual exclusion.
