不过你是初学吗，初学马上学这个好像有点早，不过也没事。原理就类似于其他dos命令一样，后面可以直接接参数，不用scanf的。
还有，更改目录用cd命令
可以通过对mian()函数传递参数来解决原型查MSDN
main( int argc, char *argv[ ], char *envp[ ] )
{
program-statements
}
argc
An integer specifying how many arguments are passed to the program from the command line. Because the program name is considered an argument, argc is at least 1.
argv
An array of null-terminated strings. It can be declared as an array of pointers to char (char *argv[ ] or wchar_t *argv[ ] for wmain) or as a pointer to pointers to char (char **argv or wchar_t **argv for wmain). The first string (argv[0]) is the program name, and each following string is an argument passed to the program from the command line. The last pointer (argv[argc]) is NULL.
