[C/C++] Thread 與 Class 的使用方式

C++11新增支持Thread標準物件（std::thread，#include<thread>），使用方式分成：

• A function pointer
  void cbThread(int params)
  {
      std::cout << "HelloWorld" << std::endl;
  }
  std::thread threadObj(cbThread, 5);


• A function1 object 
  class MyThread {
  public:
      void run(int params) {
           std::cout << "HelloWorld" << std::endl;
      }
  }:
  
  std::thread threadObj(&MyThread::run, MyThread());


• A function2 object 
  class MyThread {
  public:
      void operator()(int params) {
           std::cout << "HelloWorld" << std::endl;
      }
  }:
  
  std::thread threadObj(MyThread(), 5);


• A lambda expression
  std::thread threadObj([](int params){
      std::cout << "HelloWorld" << std::endl;
  });
