How do you make quiz master in c plus plus programm?

Answer 1

Assuming the quiz is a simple question/answer style quiz, use a map to associate question strings with answer strings. In order to prevent people from simply examining the program resources to get the answers, you should also consider encrypting the map.

For multiple choice quizzes, use a structure containing the question string, a vector of strings for the possible answers and an unsigned integer to identify the correct answer (as an index into the vector).

struct multi_choice

{

std::string question;

std::vector< std::string> choices;

unsigned answer;

multi_choice (

std::string q,

std::string c1,

std::string c2,

std::string c3,

std::string c4,

unsigned a);

const std::string& get_answer () const { return choices[answer-1]; }

};

// default constructor

multi_choice::multi_choice (

std::string q,

std::string c1,

std::string c2,

std::string c3,

std::string c4,

unsigned a)

: question (q), choices(), answer (a)

{

choices.push_back (c1);

choices.push_back (c2);

choices.push_back (c3);

choices.push_back (c4);

}

std::ostream& operator<< (std::ostream& os, const multi_choice& q)

{

os << q.question << '\n' << std::endl;

for (unsigned c=0; c<4; ++c)

os << c+1 << ") " << q.choices[c] << std::endl;

return os;

}

unsigned input_answer ()

{

unsigned num = 0;

while (1)

{

std::cout << "Your answer: ";

std::string input = "";

std::getline (std::cin, input);

std::stringstream ss (input);

if (ss >> num && num >= 1 && num <= 4)

break;

std::cout << "Invalid input.\n";

}

return (num);

}

int main()

{

std::vector questions;

questions.push_back ( multi_choice (

"In which direction does the sun rise in the morning?",

"East", "West", "North", "South", 1));

questions.push_back ( multi_choice (

"How long does a fortnight last?",

"A day", "A week", "Two weeks", "A month", 3));

// add other questions here....

unsigned points = 0;

for (unsigned q=0; q

{

std::cout << "Question " << q+1 << '\n' << std::endl;

std::cout << questions[q] << std::endl;

if (input_answer() == questions[q].answer)

std::cout << "Correct!" << std::endl;

++points;

}

else

std::cout << "Wrong!\nThe correct answer is ";

std::cout << questions[q].answer << ", ";

std::cout << questions[q].get_answer();

std::cout << std::endl;

}

std::cout << std::endl;

}

std::cout << "Quiz completed!\n" << std::endl;

std::cout << "You scored " << points;
