More verbose but goes down the path of object orientation...
#include <iostream>
#include <vector>
#include <utility>
using namespace std;
class QuestionAnswer
{
public:
QuestionAnswer(const string & question,
const string & answer)
: _question(question)
, _answer(answer)
{
}
const string & GetQuestion() const
{
return _question;
}
const string & GetAnswer() const
{
return _answer;
}
bool IsAnswerCorrect(const string & candidate) const
{
return !_answer.compare(candidate);
}
private:
string _question;
string _answer;
};
int main()
{
//would rather have something more fitting like a vector of pairs
vector<QuestionAnswer> questions
{
QuestionAnswer("What is your name?", "thaostra"),
QuestionAnswer("What is your quest?", "make this program better"),
QuestionAnswer("What is your favourite color?", "black"),
};
string input;
auto incorrect(0);
for(auto x : questions)
{
cout << x.GetQuestion();
getline(cin, input);
if(x.IsAnswerCorrect(input))
{
incorrect++;
cout << "Correct answer is: " << x.GetAnswer() << endl;

return 0;

These code refactorings have been very helpful, especially since they helped show the correct syntax for the vector of pairs. Thank you very much!

OOPS! Accidentally created a double post.
This is a working game, but I am not satisfied with it as you can tell from the comments. Also, I'm not sure how to have this be able to correctly read questions and answers from a configuration file.
