推荐答案

在分配的内存之外访问内容是未定义的行为.什么都可能发生.我听说鼻恶魔是有可能的.

Accessing stuff outside of the allocated memory is undefined behavior. Anything can happen. I hear nasal demons are a possibility.

如果您真的很幸运，可能会遇到访问冲突/段错误.如果您不走运，则程序中的其他变量可能会被覆盖，或者看不到任何可观察的事物，月亮可能变成7UP徽标，或者可能是您的右鼻孔挤出了一些讨厌的东西.

If you are really lucky, you might get an access violation/segfault. If you aren't lucky, then some other variable in the program may be overwritten, or nothing observable may happen, The moon may turn into the 7UP logo, or maybe something nasty squeezes out of your right nostril.
