After graduating from college, Melissa Malone landed a position with Orchard Creek, one of the finest children’s boutiques in the Boston area. Three years ago, Melissa was promoted to Assistant Buyer. Among her other responsibilities, Melissa is now the sole buyer for the Children’s Accessories Department.

Orchard Creek has successfully been selling children’s clothing over 25years. Its merchandising assortment includes classic children’s clothing, fashionable accessories, and unique gift items for infants, toddlers, boys, and girls.  Employee takes great pride in this store. The boutique, well known for its merchandise quality and exceptional customer service, has received many awards, including the “Readers’ Choice Award” and “Top Pick” for Best Children’s Clothing from local newspapers as well as regional magazine.

This fall, however, the Children’s Accessory Department is failing short of meeting its sales goal. During an October meeting with the department sales manager, the merchandise manager, and the advertising manager, Melissa was directed to examine her department’s performance. Within two days, Melissa must analyze the performance of the Children’s Accessories Department, compare it with the department’s six moth plan, calculate the department’s open-to-buy for the remainder of October, and identify feasible options for getting the department back on track.

Melissa reviewed her six-month plan for Orchard Creek’s Children’s Accessory Department, including the actual performance for August and September. She also observed the department’s current performance from October 1 through October 15. In her midmonth analysis, Melissa observed the following:

• Planned sales for October were $7,891
• Actual sales from October 1 through October 15 were $3,529
• The value merchandise on-order scheduled to arrive before the end of October is $2,749
• Planned markdown for October was 1,560
• Actual markdown taken from October 1 through October 15 was $715
• Stock on hand as of October 15 is valued at $22,160
• Planed EOM for October were $18,272
• Markup % is 61.5 %

When Melissa checked the department Six Month Plan, planned purchase in October was 10,439 at retail and $4, 019 at cost. However, as of October 15, the OTB in her department is very low. What immediate steps should Melissa take to improve her open-to-buy? May have to find OTB at Retail and OTB at Cost.

Parse the dirent struct to see if an entry is a directory or a file. If it is a directory, prepend "./" to the filename before printing it out. Include a main that does this below.

Please do the above code using C language.

To implement a recursive algorithm to calculates the total directory size (in bytes) of the portion of the file system rooted at the given path.

Program will rely on the following methods of the class:

• new File(pathString) or new File(parentFile,childString)
• file.length() returns the immediate disk usage(measured in bytes)
• file.isDirectory() Returns true if the File instance represents a directory; false otherwise
• file.list() Return an array of strings designating the names of all entries within the given directory

Listen to Copland's Appalachian Spring.  In one paragraph or more, discuss at least three elements that you hear in the piece that reflect the character of America (think melodies, rhythms, etc). As well as answering these questions in your discussion. Do you feel like he captures the American spirit in this piece? How do you think he does it, considering the fact that he does not use lyrics to express these images? Please give some specific examples (using minute and seconds) when referring to specific passages in the piece.

Write a bash script file that tests each file entry in the current directory. It should determine if it is a file or directory. If it is a file, it will determine if it is readable or not. If it is readable, it will display only the first 4 lines to the terminal in sorted order (just sort the first 4 lines).
If it is a directory, it should display the contents of that directory (the files and subdirectories).
NOTE: Please don’t use the read command or arguments with your script. Note that you don’t need to use either one of these methods to get a list of files in the current directory.

For the second phase of your final project, you will provide the functionality to your command interpreter. In this phase, you will add the functionality for command recognition and implement the HELP, QUIT, COPY, LIST, CD, SHOW and RUN functions.

Recall that some commands have no arguments, some have one and some have two and so your interface must handle a variable number of parameters.

Your command interpreter should do the following.

Display a prompt for the user.

• Read the user's input.
• Determine if the entered command is valid
• If it is valid, execute it and then re-display the prompt.
• If the command is not valid, display a specific, appropriate error message and re-display the prompt.  Be sure that your command interpreter differentiates between different errors that render a command invalid.
• Continue until the user enters the command “QUIT”.

If the entered command is invalid or if the number of parameters to that command is incorrect your program will print the error message and then redisplay the prompt.

If the command is valid, your program will carry out the command.

Here are specifics for each of the commands.

HELP

List the valid commands and their proper syntax.  E.g.

You rang? > HELP

The valid commands are:

RUN executable-file

LIST

LIST directory

COPY old-filename new-filename

HELP

QUIT

SHOW file

            Simply prints the given file to standard output.

QUIT

Terminates the session.  E.g.

You rang? > QUIT

Goodbye.

COPY old-filename new-filename

Creates a copy of the source file.

When you implement the COPY command, you should verify that the source file exists and is readable.  If the destination file exists you should ask the user if they wish to overwrite it before opening it to write.  Once both files have been successfully opened simple read the characters on at a time from the source file and write them to the destination file.

CD directory

         Changes the working directory to the argument if it is a valid directory name.

Your shell should display a message indicating the new directory upon successful execution o the command.  You will need to use the chdir and getcwd commands as illustrated in the sample program chDir.cpp

LIST

Displays the files in a directory

Your LIST command takes either no arguments or one argument.  The contents of the directory specified by the argument should be listed or in the case of no argument, the contents of the current directory should be listed.  The syntax is:

            LIST

or

LIST directory

The algorithm for LIST is reasonable simple.

Open the directory

Read the first entry in the directory

While not all of the directory has been displayed

            Display the entry just read

            Read the next entry

Close the directory

Working with directories is a relatively low-level operation.  To access the contents of a directory we need to use a collection of system calls declared in the <dirent.h> header file.

opendir( dname )     is passed a c-string dname and returns a pointer to the directory dname  (type DIR*) if it is found and NULL otherwise.

readdir( dPointer )  is passed a DIR* and returns a pointer to the next entry in the directory linked to dPointer or NULL if there are no more entries.

closedir( dPointer )  closes the link to the directory

The directory entries are of type dirent, a structure that contains the member d_name, which contains the name of the current entry.

Refer to chapter 17 of your UNIX text for more on programming with directories.

RUN executable-file

Executes the given program.

Your RUN command takes one argument.  The executable file specified by the argument should be run and when finished, the prompt displayed.  The syntax is:

RUN executable-file

The algorithm for RUN would be as follows.

Fork a child process.

Execute the program in the child process.

Have the parent wait until the child is finished before continuing.

This will require the following library functions

fork( )                               creates a child process and returns the PID of the child process to the parent. The child gets 0.

execl( list of cstrings )      executes a program in the current process — the first argument is the path to the executable file, the remaining arguments are the strings of the command line

wait( )                               causes the parent to block until the child finishes

Refer to chapter 18 of your UNIX text for more extensive discussion of these concepts.

As always, your program should:

• Contain carefully worded pre and post conditions for all functions.

Be readable with appropriate documentation and formatting

Tiffany City Lighting (TCL)

Located in Philadelphia, PA, Tiffany City Lighting (TCL), which designs, builds custom lamp shapes, and lamp globes, historically derived all of its sales from customers in the United States and Canada. Recently, an architectural firm that often contracted with TCL was commissioned to design several large public buildings in India. These buildings would require TCL to supply 8,100 identical lights, and the relevant terms of sale would include delivery to the Port of Mumbai where the architectural firm would take possession.

TCL designed a prototype cylindrical lampshade that measured 11 inches high and 11 inches in diameter and would be packed into cartons that measured 12 inches by 12 inches by 12 inches. (We refer to these shades as Style A.) The Style A lamp shades would cost $4 each to manufacture and weighed nine pounds each; each carton cost 60 cents and weighed one pound, meaning that each loaded Style A carton weighed 10 pounds.

In an effort to reduce packaging costs and also enhance the company’s commitment to environmental logistics, TCL also developed two prototype lamp shades (referred to as Style B and Style C) in the shape of a cone, rather than a cylinder. One advantage to conical shades is that they can be nested, that is, stacked inside each other, meaning that, unlike Style A, multiple lamp shades could be packed into a single carton. Moreover, the nested shades would also help protect each other, although a slight bit of padding would be needed between the nested shades. The production costs for the conical lampshades would be higher than those for the cylindrical shades.

TCL determined that each Style B lamp shade would cost $4.50 to manufacture and could be shipped nested, with six lamp shades per carton. The carton dimensions were 12 inches by 12 inches by 40 inches, and when holding six shades, a carton weighed 62 pounds. Each Style B carton cost $2.00, and this included padding between the shades. Each Style C lamp shade would cost $5 to make and could be shipped nested, with 10 lamp shades per carton. The carton dimensions were 12 inches by 12 inches by 48 inches, and when holding 10 shades, a carton weighed 101 pounds. Each carton cost $2.25, including padding between the individual shades.

The lamp shades would be loaded into intermodal containers and transported by rail to the Port of Baltimore. The transportation cost to Baltimore was $300 per 20-foot container, without regard to weight, although the total shipment weight could not exceed 40,000 pounds per container because of highway weight restrictions. The interior dimensions of the intermodal container were 8 feet wide by 8.5 feet high by 20 feet long. Insurance costs were 2 percent of the value of the shipment ready to be loaded aboard ship in Baltimore (i.e., all of the company’s costs up to this point). TCL learned that the transportation cost from the Port of Baltimore to the Port of Mumbai were $1000 for a 20-foot container.

Note: Please note that when cartons are loaded on to a container, they cannot exceed the container weight capacity. Please provide explanations clearly and carefully.

1. How many Style A shades can be loaded into a 20-foot container? What is effective space used per container if Style A shades are loaded? How many containers to do you need to satisfy the contract? If there are multiple ways to load the cartons into a container, you have to explore them, show the calculations, and pick the best.

2. How many Style B shades can be loaded into a 20-foot container? What is effective space used per container if Style B shades are loaded? How many containers to do you need to satisfy the contract? If there are multiple ways to load the cartons into a container, you have to explore them, show the calculations, and pick the best.

3. How many Style C shades can be loaded into a 20-foot container? What is effective space used per container if Style C shades are loaded? How many containers to do you need to satisfy the contract? If there are multiple ways to load the cartons into a container, you have to explore them, show the calculations, and pick the best.
