c++多线程编程（二）

这是道面试题目：有三个线程分别打印A、B、C,请用多线程编程实现，在屏幕上循环打印10次ABCABC…

见代码：

 #include <iostream>
 #include <Windows.h>

 using namespace std;

 HANDLE hMutex;
 int counts = ;
 int flag = ;

 void t1();
 void t2();
 void t3();

 int main() {
     HANDLE hThread = CreateThread(NULL, , (LPTHREAD_START_ROUTINE)t1, NULL, , NULL);
     hThread = CreateThread(NULL, , (LPTHREAD_START_ROUTINE)t2, NULL, , NULL);
     hThread = CreateThread(NULL, , (LPTHREAD_START_ROUTINE)t3, NULL, , NULL);
     hMutex = CreateMutex(NULL, FALSE, L"lvhuan");
     CloseHandle(hThread);
     while(counts<){
         Sleep();
     }
     return ;
 }
 void t1() {
     while (counts < ) {
         WaitForSingleObject(hMutex, INFINITE);
         if (flag == ) {
             flag = ;
             cout << 'A' << endl;
             counts++;
         }
         ReleaseMutex(hMutex);
     }
 }
 void t2() {
     while (counts < ) {
         WaitForSingleObject(hMutex, INFINITE);
         if (flag == ) {
             flag = ;
             cout << 'B' << endl;
             counts++;
         }
         ReleaseMutex(hMutex);
     }
 }
 void t3() {
     while (counts < ) {
         WaitForSingleObject(hMutex, INFINITE);
         if (flag == ) {
             flag = ;
             cout << 'C' << endl;
             counts++;
         }
         ReleaseMutex(hMutex);
     }
 }
