是否仍将C代码视为C ++? [英] Is C code still considered C++?

问题描述

对此答案的评论让我想知道.我一直认为C是C ++的适当子集，也就是说，任何有效的C代码都是有效的C ++代码扩展.我说错了吗?是否可以编写无效的C ++代码的有效C程序?

The comment to this answer got me wondering. I've always thought that C was a proper subset of C++, that is, any valid C code is valid C++ code by extension. Am I wrong about that? Is it possible to write a valid C program that is not valid C++ code?

这确实类似于这个问题.

推荐答案

通常，是的，C代码被视为C ++代码.

In general, yes C code is considered C++ code.

但是从严格意义上讲，C不是合适的子集.有几个例外.

But C is not a proper subset in a strict sense. There are a couple of exceptions.

以下是C中一些有效的内容，而这些在C ++中是无效的:

Here are some valid things in C that are not valid in C++:

int *new;//<-- new is not a keyword in C
char *p = malloc(1024); //void * to char* without cast 

也有更多示例，但是您明白了.

There are more examples too, but you get the idea.

我以前在类似的问题此处.
