我必须free()const char *吗? [英] do I have to free() a const char * ?

问题描述

我只是想知道我是否必须对const char *指针或字符串(idk是哪个)调用free().我之所以奇怪，是因为*，这似乎意味着它是一个指针.这是我的方法:

Hi, I''m just wondering if I have to call free() on a const char * pointer or string (idk which one it is). The reason why I''m wondering this is because of the *, which would seem to imply that it''s a pointer. This is how I do it:

const char * filenames[2] = {"file1.png", "file2.png"};

推荐答案

不，在这种情况下不可以，因为没有使用malloc和friends动态分配内存:)

释放它将是一个错误...

No, not in this case as the memory was not dynamically allocated using malloc and friends :)

Freeing it would be an error ...

否new —否delete.以同样的方式，没有malloc(或calloc或realloc)—没有free.这样简单吗?

PS :再次感谢CPallini

No new — no delete. In the same way, no malloc (or calloc or realloc) — no free. Isn''t that simple?
