CS 222:Computer Programming for Engineers

Homework # 4 Rubric

Most computers on the internet have a 32 bit Internet Protocol Version 4

(IPv4) address. As reading these addresses would be difficult using

binary or hexadecimal notation, IPv4 addresses are usually represented

in dotted decimal notation.

For purposes ofrepresentation,the 32 bits composing the address may

be divided intofour octets (bytes) written in decimalnumbers, each

rangingfrom 0 to 255, and concatenatedas a character string with a full

stop (ASCII 46)betweeneach number.

For example:

The first two components of theaddressindicate the computer’s locality

on the network.In theabove example, the locality is specified by the

numbers172 and16.

Anotherexample:

Locally, computers are often known by an alias (nickname) as

well. You will design and write a program to process a list of Internet

addresses from file “CS222_Inet.txt”. Your program should read a list of

up to 100 addresses andnicknames terminated bya sentinel address of

all zeros and the sentinel nickname, “NONE”.

SampleCS222_Inet.txt:

Your program will generate a report listing all computers fromthe same locality---that is, each computer with matchingvalues in the first two components of the address. In the list, the computers should be

identified by their alias. The report will be saved to file

“222_Locality_Report”.As with HW3, the report will contain the user’s

name and current date, along with the generated reportlisting.

For this assignment, you will

create your own test data files

using the sample format. Grading

will involve using different data

files with the same format.

Programstructure and design:

Create a structure typecalled:

struct address_t

with componentsfor thefour integers of an IPv4 address alongwith a

fifth componentin which to store an associatedalias of up to 10

characters.

You will then declare an array of 100 address_tstructures in which to

store the data read in from “CS222_Inet.txt”.For this exercise you may

have 2 global variablesonly:

struct address_t  addressArray[100];

FILE *outputReport

Includeat least the following UDFs (You may define your own prototypes):

a) readDataFile (Note: you may assume that the data file is syntacticallycorrect.)

b) generateLocalityRpt

c) getDateAndTime (sameas HW3)

Rubric 10 points:

• Is the source code well documented and formatted using clearly readable

indentation and white space (while viewed within vi)? 1 point

• Is struct address_t addressArray[100] properly implemented? 1 point

• Are the 3 UDFs properly implemented? 2 points

• Did you limityour program to2 (or fewer) global variables? 2points

• Is the sentinel input loop properly implemented? 2 points

• Is “222_Locality_Report” correct? 2 points

• Note:Your program must compile usinggcc in order toreceivecredit

Note: Other than prompting for the username, this project does not require an

interactive user interface.
