When writing C++ code is there any difference between:
#include <cstdlib>
and
#include <stdlib.h>
other than the former being mostly contained within the std:: namespace?
Is there any reason other than coding standards and style to use one over the other?

The first one is a C++ header and the second is a C header. Since the first uses a namespace, that would seem to be preferable. Show activity on this post. No, other than the namespace situation, they're essentially identical.
The C++ Standard Library header file (cstdlib in C++) is the header for one of the most widely used libraries by programmers of the language. This header defines a collection of functions and macros to facilitate efficient, high-performing, standardized C++ code across teams and platforms.
One easy way to differentiate these two header files is that “<stdio. h>” contains declaration of printf() and scanf() while “<stdlib. h>” contains declaration of malloc() and free(). In that sense, the main difference in these two header files can considered that, while “<stdio.
But yes, you should not count on this and always include cstdlib if you want to use rand . And in C++ code don't use rand , there are better ways to generate random numbers.
