See the bottom for how to submit your work.

Due: Before 0800 on next class day

  1. (10 pts) Read lecture notes from today. 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] Below is a program that should work as follows: Fill out the blanks below so the program works as expected. 
    
#include <iostream>
#include <fstream>
using namespace std;

int main()
{
  ifstream f1("in.txt");
  
  ____________________________;                // fill here 

  char c;
  int x, y;
  while( f1 >> c >> x >> c >> y >> c )         // fill here
  { 
    if( (x != 2) ________________ )            // fill here

      _____________________________________;   // fill here
    else

      _____________________________________;   // fill here
  }

  return 0;
}
    		   in.txt: 
     (1,2) (2,3) (2,1) (1,3) (10,1) (2,3)
    out.txt: 
     (1,2) (0,0) (2,1) (1,3) (10,1) (0,0)
  3. [70 pts] Write a program hw.cpp that prints rectangles (in text) on the screen. The outline of the rectangles should be in * characters and the inside should be empty (i.e., filled with spaces).

    Your rectangle will have a certain height and width, as well as an offset which is a number of spaces to the left of the left side of your rectangle.

    Here are some examples of how your program should work: 

    ~$ ./hw
Enter height (greater than 2): 5
Enter width  (greater than 2): 8
Enter offset: 3
   ********
   *      *
   *      *
   *      *
   ********
~$ ./hw
Enter height (greater than 2): 3
Enter width  (greater than 2): 10
Enter offset: 7
       **********
       *        *
       **********

    In writing your program, use the idea of stepwise refinement that we talked about in class. You may assume that the height and width will always be at least 2.
