Answer 1

string.h is a C header not a C++ header, period!

Answer 2

<string.h> is a C standard library header while <string> is a cpp in fact all the c standard header files have .h extension an non of cpp have .h.

Answer 3

string.h is for c compatible c++ string class string is for pure c++ string class

Answer 4

As stated, string.h and cstring are C headers (while cstring is basically a C++ wrapper for string.h), containing functions for C strings, which are char[] terminated by '\0'. You want to use the c++ class string, which header is <string>.

Answer 5

string.h is C's header file while string is C++'s header file.

Answer 6

They are entirely different headers.

<string> is C++ string class

<string.h> or <cstring> defines functions to manipulate C strings and arrays
