A self-replication program

/*************************************** ****************************
*
* This program is a self-replication program. It will copy many programs with different names using its own template,
* This replication program also has the ability to replicate itself like a virus, but it is not a virus, because
* No Destructive code exists in the program.
*
* The program is compiled and approved in turboc2.0
*
* Programming: Zheng Shaohui 2004.3.1
