Hi,
I am learning C++ and already have a good experience in C. We have
some of the application in C which we want to move it to C++. Will
there be any issue in using a C library function in C++.

Appendix C.2 of the C++ standard discusses this issue in details. C++
provides a backward compatibility with most of the C headers, and
states that their usage is are deprecated. There are few changes
introduced - eg. Declarations of certain functions like strchr and
strstr have been changed, behavior of atexit(), exit(), abort(),
longjmp() is changed, etc.

The use of the headers is deprecated. So you should use <cstdio>
instead of <stdio.hbut the functions themselves are not deprecated
so you can use strlen if you want, albeit that it is now in namespace
std and you should call std::strlen
I believe though that in <ctypeyou should use ::toupper
and ::tolower because std defines different versions of these in
<locale(not just overloads) so the original functions are not in
namespace std. Not sure what exactly is the issue, as I've never used
locale and it never really does what I would like it to do. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Imagine a cross platform library. A particular object wraps up
operating system specific functionality and presents it in a uniform
manner.
Generally, people use ifdefs to change the functionality of a
particular piece of code to match that of the native operating system
(#ifdef _WINDOWS, etc)
I'm wondering if it is possible to use templates to accomplish this
same functionality.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
