说明： 这是一个简单的编辑器雏形，这里用到了屏幕开发库 curses 和键盘函数 keypad，程序可移动光标,输入,删除,增加代码就可成为功能强大的编辑器了，
编译程序:gcc -I/usr/include/ncurses edit.c -o edit -lncurses (This is a simple editor prototype, here the screen used for the development of curses and keyboard function keypad, procedures movable cursor input, deleted and code can be as powerful editor, compiler :-I/usr/include/ncurses edit.c gcc-o edit-ln curses)
