(In this paper, two types of threads are set up, one is producer and the other is consumer; the data structure of buffer is established; the producer or consumer is started randomly by using the menu; the buffer is displayed on the window; the window display is updated with each operation of the buffer by the thread; the data structure of the buffer is established; Operating system: windows10 development language: C language development tool: dev C++)
