c++ - stdio.h 在 C++ 中不是标准的？

Question

我知道大多数编译器都允许:

#include <stdio.h>

和

#include <cstdio>

但有人认为 <stdio.h>实际上不是 C++ 标准。这是真的吗？

Answer 1

stdio.h是标准的，但已弃用。永远喜欢 cstdio在 C++ 中。

[n3290: C.3.1/1]: For compatibility with the Standard C library, the C++ standard library provides the 18 C headers (D.5), but their use is deprecated in C++.

[n3290: D.5/3]: [ Example: The header <cstdlib> assuredly provides its declarations and definitions within the namespace std. It may also provide these names within the global namespace. The header <stdlib.h> assuredly provides the same declarations and definitions within the global namespace, much as in the C Standard. It may also provide these names within the namespace std. —end example ]
