1. [20pts] Read today's lecture notes carefully and write key points (with a few sentences) below.

   What confuses me:
   
   
   
   
   Key points:
   
   

2. [20pts] Assume the following delcarations and fill in the table with either the type of the given expression, or "error" if appropriate.
   

   
   struct Point {
     double x, y;
   };
   
   struct Trial {
     double stime, etime;
     Point *ways;
     int numways;
   };
   
   struct Subject {
     string name;
     int id;
     Trial pre, post;
   };
   
   Subject S;
   Subject* A;
   int i, j;
    

   expression	type
   S.id
   A[i]
   A.pre.ways[i][j]
   S.post = A[i].pre;
   A[i].post.ways
   S.pre.ways[i]
   A[i].id = S.ways[i].y
   A[i].pre.ways[j].x
   A[i].post.ways.x
   S.pre.numways++
3. [60pts] Write a program called raffle.cpp 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:

   ~/$ ./raffle
   How many people? 3
   Person 1 name: Dave
   Person 1 tickets: 650 205 592 377
   Person 2 name: Erin
   Person 2 tickets: 324 980 769 230
   Person 3 name: Jim
   Person 3 tickets: 442 230 296 230
   Winning ticket: 592
   Dave won!
   
   ~/$ ./raffle
   How many people? 2
   Person 1 name: Erin
   Person 1 tickets: 324 980 769 230
   Person 2 name: Jim
   Person 2 tickets: 442 230 296 230
   Winning ticket: 592
   
   ~/$ ./raffle
   How many people? 2
   Person 1 name: Erin
   Person 1 tickets: 324 980 769 230
   Person 2 name: Jim
   Person 2 tickets: 442 230 296 230
   Winning ticket: 230
   Erin won!
   Jim won!
