这是一个非常简单的问题，但是我真的不知道答案.例如:C ++上的某些程序正在运行，我对其进行了修改和编译.程序是否需要重新启动?

附注:Ubuntu 12.04 LTS

This is a very simple question, but I don''t know the answer,really. For example:some program on C++ is running, and I modified and compiled it. Program needs to be restarted or not?

推荐答案

是的，是的，当您启动程序时，指令会复制到内存中，更改原始文件不会对其进行更新.另外，它在运行时将如何切换?仅仅因为它在原始代码中的第n条指令上并不意味着跳转到新代码中的该指令对程序是有效状态.

Yes, when you launch a program the instructions are copied into memory, changing the original file won''t update it. Plus, how would it switch while it was running? Just because it''s on the nth instruction in the original code doesn''t mean jumping to that instruction in the new code is a valid state for the program.
