Describe help received: ________________________________________________________

  • Due before class on Monday, April 3
  • This homework contains code to be submitted electronically. Put your code in a folder called hw29 and submit using the 204sub command.
  • This is an electronic homework and you do not need to print out anything to turn in during class.

Assignment

  1. Required reading: Section 4 (Structs with pointers and arrays)) from the Unit 8 notes.
  2. Write a program called raffle.c that simulates a raffle lottery. Your program will first read in a series of names and exactly 4 raffle ticket numbers for each name, and then "draw" the winning number (by reading again), and finally print out the name(s) of all winners who have that winning number.

    Of course, you should create a struct for each person that contains their name as well as an array of their ticket numbers.

    Example runs:

    roche@ubuntu$ ./raffle

    Person 3 name: Jim
    Person 3 tickets: 442 230 296 230
    Winning ticket: 592
    Dave won!
