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:

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
