再大的困难也难不

#include <windows.h>
#include <stdio.h>static int number=20;DWORD WINAPI ThreadOne(LPVOID lpParameter)
{while(1){if(number>0){printf("窗体1售出第%d张票...\n",number);Sleep(1000);number--;}}return 0;
}
DWORD WINAPI ThreadTwo(LPVOID lpParameter)
{while(1){if(number>0){printf("窗体2售出第%d张票...\n",number);Sleep(1000);number--;}}return 0;
}int main()
{HANDLE HOne,HTwo;printf("***********************vpoet******************\n");HOne=CreateThread(NULL,0,ThreadOne,NULL,0,NULL);printf("窗体1售票開始:\n");HTwo=CreateThread(NULL,0,ThreadTwo,NULL,0,NULL);printf("窗体2售票開始:\n");CloseHandle(HOne);CloseHandle(HTwo);while(TRUE){if(number==0){printf("MainThread Over!\n");return 0;}else{continue;} }return 0;
}

执行结果:

#include <windows.h>
#include <stdio.h>static int number=10;
CRITICAL_SECTION Section;DWORD WINAPI ThreadOne(LPVOID lpParameter)
{while(1){EnterCriticalSection(&Section);if(number>0){printf("窗体1售出第%d张票...\n",number);number--;Sleep(1000);       }LeaveCriticalSection(&Section);}return 0;
}
DWORD WINAPI ThreadTwo(LPVOID lpParameter)
{while(1){EnterCriticalSection(&Section);if(number>0){printf("窗体2售出第%d张票...\n",number);Sleep(1000);number--;}LeaveCriticalSection(&Section);}return 0;
}int main()
{HANDLE HOne,HTwo;InitializeCriticalSection(&Section);printf("***********************vpoet******************\n");HOne=CreateThread(NULL,0,ThreadOne,NULL,0,NULL);printf("窗体1售票開始:\n");HTwo=CreateThread(NULL,0,ThreadTwo,NULL,0,NULL);printf("窗体2售票開始:\n");CloseHandle(HOne);CloseHandle(HTwo);while(TRUE){if(number==0){printf("不好意思,票卖完了!\n");DeleteCriticalSection(&Section);return 0;}else{continue;}   }return 0;
}

执行结果例如以下:
