如何使这段代码在c ++中运行就像在Batch中一样。由于某种原因，它不会使用％ipcode％。所以我无法输入ip'以查看是否有在线。

这里的问题是对system（）的两次调用都设置了一个独立的cmd.exe独立运行。因此，第二个电话不能看到您在第一次调用时提示并设置的％ipcode％变量的值。


我建议使用C代码提示输入ipcode，然后将答案格式化为第二个命令所以只调用一次system（）。

The trouble here is that the two calls to system() each set up a separate, independent run of cmd.exe. So, the second call cannot "see" the value of the %ipcode% variable you prompted for and set during the first call.

I would suggest using C code to prompt for the ipcode, then format the answer into the second command and so call system() just once.

这里的麻烦是两次调用system（）各自设置一个单独的，独立运行cmd.exe。因此，第二个电话不能看到您在第一次调用时提示并设置的％ipcode％变量的值。

哦，好的电话。我完全错过了第一次通话中发生的事情...


很好的抓住，ravenspoint。

Ooooh, good call. I totally missed what was going on in the first call...

Nice catch, ravenspoint.
