A header file contains a class template, and in that class there is a C++ string object.
Group of answer choices(Pick one)
1)There should be a #include for the string library AND a using namespace std; in the header file.
2)There should be a #include for the string library.
3)There should be a #include for the string library AND a using namespace std; in the main program's CPP file, written before the H file's include.

Correct Answer:-
1
(There should be a #include for the string library AND a using namespace std; in the header file)
Explanation:-
We can also include iostream library instead of string library but we must need to use using namespace std; because string is a part of std. If we dont want to use it - We can use an alternate by only including string library using #include and declaring string like below:
std::string
You can see below that program is only running when we include string library as well as a using namespace std; in header file!

Objective
You are given a partial implementation of one header
file, GildedRose.h. Item is a class that holds the information for
each item for the inn. GildedRose is a class that holds an internal
listing of many Item objects. This inventory should hold at least
10 items. For this you can use arrays, the std::array class, or
even the vector class.
Complete the implementation of these classes, adding
public/private member variables and functions as needed. You should
choose an appropriate...
