c\c++: <strings.h> <string.h> <string> <cstring> recap

 

<string.h> v.s. <string>

string.h contains old functions like strcpy, strlen,

string primiraly contains std::string class.

It should also be noted that using string.h is deprecated within C++. If you need the functionality contained within, you should use the header cstring. This more or less completely bypasses the issue of "What's the difference between these two" because it's very obvious that one is from the C library. – Mike Bantegui

<cstring> v.s. <string>

http://www.cplusplus.com/forum/general/38801/

“<cstring> is basically a header containing a set of functions for dealing with C-style strings (char*). <string>, on the other hand, is header that allows you to use C++-style strings (std::string), which can do a lot of if not all of the functions provided in <cstring> on their own. - Albatross“

Use string. cstring is so 1970's. string is a modern way to represent strings in c++. you'll need to learn cstring because you will run into code that uses it. but cstring is responsible for lots of unsafe code.  - PanGalactic“

<strings.h> v.s <string.h>

Typically <strings.h> just adds some useful but non-standard additional string functions to the standard header <string.h>. For maximum portability you should only use <string.h> but if you need the functions in <strings.h> more than you need portability then you can use <strings.h> instead of <string.h>.
