是（字符）数组的内存走出去的范围中解放出来？ [英] Is the memory of a (character) array freed by going out of scope?

问题描述

有很大关系<一个href=\"http://stackoverflow.com/questions/1322884/c-does-going-out-of-scope-like-this-free-the-associated-memory\">my previous问题，但我发现这是一个单独的问题，我无法找到一个坚实的答案。

Very much related to my previous question, but I found this to be a separate issue and am unable to find a solid answer to this.

是由一个（角色）所使用的存储阵列通过走出去的范围中解脱出来？

Is the memory used by a (character) array freed by going out of scope?

一个例子：

void method1()
{
  char str[10];
  // manipulate str
}

所以方法1调用后，被释放由乙方（10字节）使用的内存，或者我需要显式调用免费这个呢？

So after the method1 call, is the memory used by str (10 bytes) freed, or do I need to explicitly call free on this as well?

我的直觉告诉我，这是原始类型的只是一个简单的数组，所以它的自动释放。我很怀疑因为在C你不能假设任何事情被自动释放。

My intuition tells me this is just a simple array of primitive types, so it's automatically freed. I'm in doubt because in C you can't assume anything to be automatically freed.

推荐答案

在此情况下，没有你不需要打电话免费。值海峡，是一个基于堆栈的值，当特定的方法/范围退出将被清理。

In this case no you do not need to call free. The value "str" is a stack based value which will be cleaned up when that particular method / scope is exited.

您只需要拨打免费的，它们通过明确的malloc创造的价值。

You only need to call free on values which are explicitly created via malloc.
