1. (10 pts) Read today's lecture notes. Honestly declare how you read the notes.
   1. (10 pts) I read the notes carefully. I have a good understanding of the topics therein.
   2. (10 pts) I read the notes carefully, but I don't really understand the following points well:

   3. (0 pts) I didn't read the notes carefully.
2. [10pts] Assume the following declarations 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. [80 pts] Download hw.cpp.

   The program is supposed to work as follows: It reads a data file containing offerred course sections like sections.txt. Then, it allows the user to search for sections based on a course name, or a section number. On the right is a sample run (with user input in red). Your task: Read the starter code hw.cpp carefully and understand what each function does or should do. (You may want to refer to the course notes on pass-by-address and sorting-and-search). Add code in hw.cpp so that the program works correctly. Don't touch the main function given in the starter code.

   ~/$ ./hw Filename: sections.txt > course EE301 EE301 1111 M1,TR12 EE301 2222 M2,WF12 EE301 5555 M5,TR56 > section 4040 SC112 4040 M4,WF4,T56 > course EE327 EE327 3333 MWF3,R34 > section 3333 EE327 3333 MWF3,R34 > quit
