n-line code comments no fewer than every 5 lines of code which describe your algorithmic steps. Syntax transcriptions of the code are not considered in-line code comments!

INSTRUCTIONS TO CANDIDATES
ANSWER ALL QUESTIONS

Need both assignments done and plz follow the instructions given in the programming document. If anyhting is needed plz let me know. The other two files with Proj are for Project 2.

 

Your project deliverables are to be posted to CUNY Blackboard using the Project 1 link.

1) Only one source code file as follows with filename as in the example where you will put

your own first initial and lastname and your

 own section number. I show the example for my own name with an example section 23:

JSvadlenka_prj1_sect23_src.c (or .cpp)

 a) At top of the file: your name in comments, for example: // First_Name Last_Name

 b) Next, the gcc or g++ code compilation and linkage command, for example: // gcc

JSvadlenka_prj1_sect23_src.c -o JSvadlenka_prj1_sect23_src.exe

 

 c) In-line code comments no fewer than every 5 lines of code which describe your algorithmic

steps. Syntax transcriptions of the code are

 not considered in-line code comments! (For example, I do not want to see the comment for

i++ which says "Increment i.")

2) An MS Word or PDF document with a write-up of your software design and an explanation of

the issues encountered and resolved. (1 page)

 Filename should be according to this example of my own name:

JSvadlenka_prj1_sect23_wrt.doc (or pdf)

Project Description

-------------------

In your first project you will create a program that, when executed, has both a parent

process and a child process. You use the fork()

system call to create a child process.

As in the cpfile.c program, your program takes two command line arguments for a source text

file name and a target filename

with the same semantics (source file exists in the same directory as the executable and the

target file does not already exist

in this same directory).

The parent process will read the source file contents in 128-character chunks (as in

cpfile.c) and write it to a pipe (instead of an output file).

The child process will read the contents of the pipe in 128-character chunks and write the

contents to both the target file and to the display screen in

128-character chunks. Obviously, the last chunk may be less than 128 characters based on the

size of the source file.

1) Your program accepts two command line arguments which are the name of the input file to be

read and the output file to be created.

2) Your program will make use of the POSIX system I/O calls discussed in lectures.

3) You are NOT permitted to use any C++ nor C standard I/O library functions nor cin nor

cout. Furthermore, you cannot use

 any C++ nor C standard library functions for string operations.

4) The parent and child processes may each use their own character buffer array of size 128.

5) I will test your code with source text files having 1 or more lines of text and each line

may have more than 128 characters.

6) This project essentially utilizes the code of cpfile.c for file copying and the code of

Fig 3.2.2 for pipes in the textbook.
