在linux环境下编写一个控制台应用程序，程序中有一个共享的整型变量shared_var，初始值为0；创建一个线程并使其立即与主线程并发执行。新创建的线程与主线程均不断地循环，并输出shared_var 的值。主线程在循环中不断地对shared_var 进行加1操作，即每次循环shared_var 被加1；而新创建的线程则不断地对shared_var 进行减1 操作，即每次循环shared_var 被减1。观察程序运行的结果，并对你看到的现象进行解释。(Written in the linux environment a console application, the program has a shared integer variable shared_var, the initial value of 0 create A thread and make it run concurrently with the main thread immediately. The newly created thread and main thread are constantly circulating, and the output shared_var Value. The main thread in a loop constantly on shared_var are incremented, that is plus 1 for each cycle shared_var and the new line created Process is constantly on the shared_var decremented, that is, each cycle shared_var is decreased by 1. Observe the results of running the program, and you To explain the phenomenon seen.)

说明：  本系统是一套机载数据采集模块和远程终端。数据采集模块可以独立采集对象（小型飞机或航模）的姿态、高度等参数，并通过无线方式发送到远程终端；远程终端具有数据的实时显示、报警功能，并可记录数据完成回放。 在本设计方案中，使用MPU6050模块测量小型飞机的姿态角、航向角，使用气压测量模块与超声波测量模块来确定飞机的高度，使用WIFI模块进行数据传输，使用北斗卫星定位模块进行小型飞机的位置确定，在远程终端PC机上对数据进行解算，并采用MATLAB GUI对采集到的数据进行图形化的显示。(This system is a set of airborne data acquisition module and remote terminal. The data acquisition module can independently collect the attitude and altitude parameters of the object (small aircraft or model) and send them to the remote terminal by wireless mode. The remote terminal has the functions of real-time data display and alarm, and can record and play back the data. In this design, MPU6050 module is used to measure the attitude angle and heading angle of small aircraft, air pressure measurement module and ultrasonic measurement module are used to determine the height of the aircraft, WIFI module is used to transmit data, Beidou satellite positioning module is used to determine the position of small aircraft, and data is obtained on remote terminal PC. The calculation is carried out, and the collected data is displayed graphically by using MATLAB GUI.)
