今天就差不多完成了ai编码c语言程序的过程

不断改进的提示语：

write a program in c and compile by gcc, create a system tray icon, when the icon is right clicked, pop up an exit menu to exit the program, listen in backgroup, when key combination Ctrl+Left Arrow is pressed, get current active window in windows, then set the window size to half the screen resolution and locate to left half screen, when Ctrl+Right Arrow is pressed, get the current active window in windows and fix into the right half of the screen, when ctrl+up arrow is pressed, fix the current active window to upper half of the screen, when ctrl+down arrow is pressed, fix the current active window into the bottom half of the screen, when ctrl+alt+enter is pressed, if the current active window is in max size, restore its size and location to normal, or else, set it to max size if its size and location is normal

结果：

程序已经可以正常运行，

注意， 编译的时候要加上-mwindows这个选项，不然会多出来一个黑空控制台窗口： gcc window_resizer.c -o window_resizer -mwindows，

然后 直接执行程序就可以看到托盘图标可以退出，正常使用了， 太开心了。
