命令解释器的实现,将输入文件“batch”中所列的程序启动运行,读懂实例代码sm1.cpp并且修改为目标代码,将sm1.cpp中的参数由待启动程序改为待读文件,并且通过文件操作获取待启动进程。-Command interpreter implementation, the input file " batch"　procedures set forth in start running, read and modify the sample code sm1.cpp target code, sm1.cpp parameters to be changed by the program to be started reading documents, file operations through the process of acquisition to be started.
