See the bottom for how to submit your work.

Due: Before 0800 on next class day

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. [20pts] Assume the declarations and function definitions below. Fill in the table.
   Note: "error" is a possiblity!
   Note: each question is independent, i.e. no side effects of one expression should be taken to carry over to the next.

   string* S = new string[2]; S[0] = "happy"; S[1] = "sad"; string foo() { return "good"; } char bar(string str) { int i = str.length()-1; return str[i]; } bool iscap(char c) { return (c >= 'A' && c <= 'Z'); }

   expression type (or error!) value (or error!) S N/A S[1] S[1][2] - 'a' + 'A' foo() + 2.5 S[0][0] = S[1][0] bar(foo()) foo()[3] bar(S[0][0]) iscap(S[0]) iscap(S[0][0])

3. [60 pts] Write a program in a file named hw.cpp that reads in information about a series of flights and prints out information about the reverse journey.

   After specifying how many legs are in the trip, the user will type in pairs of airports like ABC->XYZ. Each airport will always be specified by a 3-letter code, separated with ->.

   After reading in information on each leg of the journey, your program should print out the reverse journey in one line with -> between the airport names.

   Example runs:

   ~/$ ./hw How many legs? 3 BWI->JFK JFK->BUF BUF->YYZ Reverse trip: YYZ->BUF->JFK->BWI	~/$ ./hw How many legs? 1 DCA->DFW Reverse trip: DFW->DCA
   ~/$ ./hw How many legs? 4 LHR->ORD ORD->OGG OGG->NRT NRT->BNE Reverse trip: BNE->NRT->OGG->ORD->LHR

4. [10 pts] Carefully read the project 2 description and requirements. Honestly declare how you read the project.
   1. (10 pts) I read the project carefully. I have a good understanding of the topics therein.
   2. (10 pts) I read the project carefully, but I don't really understand the following points well:

   3. (0 pts) I didn't read the project carefully.
5. Project 2 is now starting. Please write by hand the honor pledge below and then sign your name. Turn this in with your homework, on a separate sheet of paper:
   The Military Service I am a part of is bound by honor and integrity. I will not compromise our values by giving or receiving unauthorized help on project 2.
