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?

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.
