Does anyone know what header file is missing? - c++

Question

This code works on Code Blocks but not on Visual Studio:
// A simple program that prints string test1:
#include <iostream>
#include <vector>
using namespace std;
int main()
{
vector<string> test1 = { "pooping","reading" };
for (vector<string>::iterator iter = test1.begin(); iter != test1.end(); iter++)
{
cout << *iter << endl;
}
system("pause");
}
The error that Visual Studio Outputs:
Error C2679 binary '<<': no operator found which takes a right-hand operand of type 'std::_Vector_iterator<std::_Vector_val<std::_Simple_types<std::basic_string<char,std::char_traits<char>,std::allocator<char>>>>>' (or there is no acceptable conversion)

Answer 1

std::basic_string is officially defined in the <string> header. See cppreference.

Answer 2

#include<string>
The class template basic_string stores and manipulates sequences of char-like objects. The class is dependent neither on the character type nor on the nature of operations on that type. The definitions of the operations are supplied via the Traits template parameter - a specialization of std::char_traits or a compatible traits class. For more details please see
std::basic_string

Answer 3

after adding header , program won't compile and it will throw error
"error: in C++98 'test1' must be initialized by constructor, not by '{...}'"
check the below program followed another method to initialize vector.
As suggested by other you need to add
#include<string>
// A simple program that prints string test1:
#include <iostream>
#include <vector>
#include<string>
using namespace std;
int main()
{
static const string arr[] = {"pooping","reading"};
vector<string> test1 (arr, arr + sizeof(arr) / sizeof(arr[0]) );
for (vector<string>::iterator iter = test1.begin(); iter != test1.end(); iter++)
{
cout << *iter << endl;
}
system("pause");
}
