linux simple multi-threaded application

1. Environment Configuration

When include the header file #include, compile under linux multithreading, always will be reported this wrong

：对‘pthread_create’未定义的引用

You can use the link to the relevant library in the CMakeLists.txt

find_package(Threads REQUIRED)
if(THREADS_HAVE_PTHREAD_ARG)
  set_property(TARGET my_app PROPERTY COMPILE_OPTIONS "-pthread")
  set_property(TARGET my_app PROPERTY INTERFACE_COMPILE_OPTIONS "-pthread")
endif()
if(CMAKE_THREAD_LIBS_INIT)
  target_link_libraries(my_app "${CMAKE_THREAD_LIBS_INIT}")
endif()

line 34 of the program there's a small mistake, should be "= = "to" = "

if ((val = testMultithreadWallet()) != 5000)

The results of running this program are as follows inside and found the results for each run are different, with the title Lord said phenomenon consistent, but do not know why, my results are out of the 4000 yuan

Error at count = 945 Money in Wallet = 4000
Error at count = 961 Money in Wallet = 4000

mMoney the last paragraph of the first 10 lines of code inside of this money should be changed to
article content brief introduction

//第一种修复竞争方法
  std::mutex mutex;
  {
  	mutex.lock();
  	fun();
  	mutex.unlock();
  }
  //第二种修复方法
  {
  	std::lock_guard<std::mutex> lockGuard(mutex)
  	fun();
  }

The second way a little better than the first, because not only can run at the end of the braces is automatically unlocked, unlocking can occur when abnormal internal braces, here's a way better elsewhere learned from std :: unique_lock, but still did not understand, here today to see the
