Why does string not work?

[youknowme]

// Attempt to declare a string object
#include <iostream>
#include <string>
#include <vector>

int main()
{

std::string const end_input('END');
std::vector<std::string> words;
std::string aword;


}

You used single quotes for a string, change that to double quotes:
std::string const end_input("END");
