The functions used in the source code are simple and easy to understand. They are described in the source code with comments.

The following library functions are used:

  1. <stdio.h> – for standard input output
  2. <conio.h> – for console input output
  3. <ctype.h> – for case sensitivity
  4. <time.h> – for generating a random number
  5. <windows.h> – for declaration of all the function especially <MMSystem.h>
  6. <MMSystem.h> – multimedia function for adding multimedia files.


The following user defined functions are used:

  1. void open_sector(char question[20], char answer[20]) : This is the most important function. It contains two other functions named as ‘void questions() and ‘void answer_match()’. It opens both the question and answer files in reading mode. After that it calls both the functions.



  1. void question(): First a random number is generated by using srand(time(0)), rand() and <time.h>. Then it prints a random question with options.



  1. void answer_match(): First an input is taken from the user then it matches with the correct answer. If it doesn’t match the answer then the game will take user to the main menu.



  1. void add_record(): After every game ends. The name of the player and the prize money is printed in a separated file.
