c_cpp：编译脚本regcc：编译当前目录的单文件源程序
一、说明
1、单文件的源程序：源程序是一个独立完整的文件。
2、regcc功能：
2.1、显示所有文件：在当前目录，显示所有文件；
2.2、显示可执行文件：在当前目录，显示所有可执行文件；
2.3、编译C源文件：在当前目录，编译所有的C源文件并且生成可执行文件；
2.4、删除可执行文件：在当前目录，删除与“C源文件”同名的可执行文件；
2.5、所有：显示所有可执行文件；删除C源程序编译后的可执行文件；显示所有文件；编译所有C源程序文件并且生成可执行文件。
3、regcc 脚本格式：
3.1、regcc 脚本格式： ./regcc <options>
3.2、regcc 选项说明：
选项 功能
a 在当前目录，显示所有的文件。
l 在当前目录 ，显示所有的可以执行文件。
d 在当前目录 ，删除所有与“c源文件”同名的可执行文件。
c 在当前目录，编译所有的C源程序文件并且生成可执行文件。
x （x=all, all=aldc）在当前目录并且存在文件 “ *.c ” ，删除所有与“c源文件”同名的可执行文件；编译所有文件“ *.c”生成“可执行文件”； 显示所有文件。
3.3、regcc 脚本使用示例：
3.3.1、./regcc a // 显示当前目录的所有文件；
3.3.2、./regcc l // 显示当前目录所有可执行文件；
3.3.3、./regcc d // 删除当前目录与C源程序同名的所有可执行的文件；
