  • Due before class on Monday, April 10
  • This homework contains code to be submitted electronically. Put your code in a folder called hw30 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: Sections 5 (Sorting structs) and 6 (composition of structs) from the Unit 8 notes.
  2. First download the partially-complete program bdays.c from this link. This is a program to read in people's names and birthdays and then print them out in order from youngest to oldest. Most of the program has been written for you, including two struct definitions, two useful functions, and the main function. All you should change is to fill in the definitions of functions before and write_person.

    Example runs:
