Chapter 17 Challenge 3 Page 1119 Write a program that creates a map of the U.S. states as keys, and their capitals as values.

The program should then randomly quiz the by displaying the name of a state and ask the user to enter the states capital. The program should keep a count of correct and incorrect responses.

Example:

// Capital Quiz

#include #include #include #include #include

// Function prototypes

void split(const string&, char, vector&); void getMappings(map &); void quiz(map, int);

int main() {

const int NUM_QUESTIONS = 5; map capitals;

// Build the map.

getMappings(capitals);

// Run the quiz.

quiz(capitals, NUM_QUESTIONS);

system("pause");

return 0; }

//************************************************************** // The split function splits s into tokens, using delim as the * // delimiter. The tokens are added to the tokens vector. * // (See Chapter 10 in your textbook for more information about * // this function.) * //************************************************************** void split(const string& s, char delim, vector& tokens) { }

//**************************************************************

// The getMappings function reads the states and capitals // from a file named StateCapitals.txt and stores them as // key-value pairs in the capitals parameter, that is passed // by reference. //************************************************************** void getMappings(map &capitals) }

void quiz(map capitals, int numQuestions){}

* * *
