Assignment 2:                    Quiz Night  Game Engine

The game engine loads questions and their answers from a file and asks the questions to the user who needs to provide the answer. The game can provide clues to the user, with the amount of information provided depending on the level of difficulty.

Details

1.         The questions and answers are in a file. The file is provided as a command line argument to the application.

2.         In the question and answer file each line has a question and its answer. The answers are always one word.

3.         The question always ends in ‘?’ then there is a space and following that the answer. For example:

What is the capital of France? Paris

4.         The application takes a second command line argument, a number <10 that represents the difficulty level.

    The program should:

·           at the start

-          load the questions and answers from the file

-          print out the number of questions in the quiz

·           start asking questions

-     for each question, display a clue (if available, see below); the user has one attempt only, and the program is case insensitive (accepts both lower and upper case answers)

-     after each question display the number of questions asked and the number of correctly answered

   questions so far. Example:   

      Score: 5/7

·           at the end store the results in a file quiz_history.txt by appending to the file one line containing:

-          name of the quiz file

-          number of questions answered correctly

-          total number of questions

-          difficulty level
