EECS 213
Homework H1: Numbers

This is an individual assignment. No partners. Submit your answers by email. Any clarifications and revisions to the assignment will be posted on the course help system.

Note: pages and exercise numbers below are for the 2nd edition of the text.

Create three files:

• the homework header file, hw1.h -- use this file as is. Do not make any changes to this file without contacting me first.
• your homework solution file with the name hw1.c
• a separate test file, e.g., test_hw1.c, that includes a main() function that does whatever testing you think you need to do.

The file hw1.c should contain only the code neeede to implemet the functions in hw1.h. All testing and printing code should be in test_hw1.c

In hw1.c and test_hw1.c, be sure to #include "hw1.h". Never include hw1.c. Include's are only for header files.

Obey the rules on page 120. A lot is forbidden.

• Ex. 2.60: replace_byte() -- an implicit cast is OK here because this mixes an int with unsigned parameters.
• Ex. 2.65: odd_ones()
• Ex. 2.83: float_le()
• Ex. 2.87: see table format below

For Ex. 2.87, put your table entries in hw1.c in a comment like this:

// Ex. 2.87
//
// 1 01111 001  -9/8 1 01111 0010 -9/8
// 0 10110 011  ...    ...        ...
// 1 00111 010  ...    ...        ...
// 0 00000 111  ...    ...        ...
// 1 11100 000  ...    ...        ...
// 0 10111 100  ...    ...        ...

You can do your code development using any IDE you choose, but the compiler underneath should be gcc, since that's how it will be tested. If it doesn't compile, I can't grade it.

Hand In Instructions

• Put comments identifying yourself at the start of hw1.c.
• Remove any extraneous code.
• Email hw1.c to c-riesbeck in the grand domain of northwestern.edu. Put EECS 213 Homework H1 in the Subject line.
