Declaring String variable in C++

Question

I use Dev-C++ which has GCC 4.9.2 C++ compiler. I am confused on where and where not to use the following for declaring a string variable:

because everything compiles and run in devc++, I am unable to understand the concept behind all these

`std::string`: _"Defined in header "_ see: http://en.cppreference.com/w/cpp/string/basic_string Also headers: http://en.cppreference.com/w/cpp/header — Richard Critten, Jun 11 '17 at 11:00

To use std::string always use #include <string>.

The other header files you mentioned have nothing to do with std::string.

The std namespace scope can be omitted if you have an appropriate using statement like

using std::string;

or

using namespace std;
