W800/W801 SDK C++編譯Demo

1.把main.c後綴名改為main.cpp

    printf("\n user task \n");

    Line line;
    // 設置長度
    line.setLength(6.0); 
    printf("Length of line : %lf\n", line.getLength());

#if DEMO_CONSOLE
    CreateDemoTask();
#endif
//用戶自己的task
}

#ifdef __cplusplus
}

2.LINKFLAGS加-lsupc++(不然包含析構函數會報錯)

3.Demo效果
