1. Done in c++, Read an unsorted keywords file once to determine how many words are in the file.
2. Allocate memory dynamically to store the unsorted keywords in an array of strings or an array of c-strings. (Hint: be sure to clear your input file stream before re-reading the file)
3. Reread the keywords file a second time and store the words in the dynamically allocated array of strings or c-strings
4. Sort the array of key words. (Hint: be sure to check your sorted array of key words - there should be 84)
5. no victor use if possible.
6. Search a C++ program input file for occurrences of the keywords:
   • Read one line at a time from the C++ program file into a cstring. (Hint: use the istream::getline function - see example below)
   • Parse each line into separate words. Ignore any words that are inside a C++-style comment. (Hint: use strtok)
   • Search the keyword array to determine if each word is a keyword (Hint: use a binary search or a sequential search)
   • For keywords, print the line number, the keyword, and the position of the keyword in the line. (Hint: use the difference of two pointers)
   • Keep a count of the number of keywords found

Program Requirements

• This zipped file(http://voyager.deanza.edu/~bentley/cis22b/ass4files.zip) contains the keywords file and the C++ program file for searching.
• Use a char array to hold each line from the C++ program file. “Parse” each line into individual words for searching. Note, you may not use the stringstream classes for this assignment.
• Make sure you check the input file for successful opens.
• Your output should match the format show below with the correct line number and position of each word in the line. The line character positions start at zero. Note, there are more than 50 lines of output.

Program Output

Your output should look like this:

Program Hints

• Follow the program steps. Write only one part of the program at a time. Test each part before you proceed to the next step. Do not continue if one part has a problem. Ask for help with a step, if you can't get it to work. Remember to allow plenty of time for this assignment.
• Use a small keyword file and a small test C++ program file initially as you are developing your code.
• Use strstr() to find the // of a C++-style comment.
• Use strtok() for the parsing of each line. You should "parse out" much of the program "punctuation".
• You might want to make a copy of each line (maybe as a string) to determine the position of the keyword in the line. This is because strtok() destroys the original line.
• Xcode users: There is a \r at the end of each line in the test file. You can suppress it by adding "\r" as a delimiter for strtok().
• Your program should produce more than 50 lines of output and you should find more than 70 keywords (many are repeats).

The keyword file looks like this:

The C++ program file looks like this:

istream::getline example

Step 1: Your program will now take its input from this file instead of from the user. Here's what you want to do:

1. Remove the call to getUserInput(). You can also remove its definition and prototype if you like.
2. For reasons that will become clear later, don't close the file until just before the return statement at the end of main.

Run your code to make sure that the file is opened and read correctly. Hint: you may test the correctness of code by printing the contents of this file, one string at a time.

//Code to be adjusted

#include<iostream>

#include<string>

using namespace std;

//prompts user for input and returns a string containing userinput

string getUserInput(){

string input;

getline(cin,input);

return input;

}

//returns true if given character is vowel else false

bool isVowel(char c){

if(c=='a'||c=='e'||c=='i'||c=='o'||c=='u'||c=='A'||c=='E'||c=='I'||c=='O'||c=='U')

return true;

return false;

}

//returns true if given character is an alphabet else false

bool isAlphabet(char c){

if((c >= 'a' && c<='z') || (c >= 'A' && c<='Z'))

return true;

return false;

}

//returns true if given character is digit else false

bool isNumber(char c){

if(c >= '0' && c <= '9')

return true;

return false;

}

//Prints the report

void printReport(int vowels, int cons, int digit, int special){

cout<<"Vowels: "<<vowels<<endl;

cout<<"Consonants: "<<cons<<endl;

cout<<"Digits: "<<digit<<endl;

cout<<"Special characters: "<<special<<endl;

}

//driver function

int main(){

//to store user string

string input;

//counters for number of vowels, consonants, digits and special characters respectively

int vowel = 0;

int consonant = 0;

int digit = 0;

int specialChar = 0;

//gets user input

input = getUserInput();

//iterating over input and counting the number of vowels, consonants, digits and special characters

for (int i=0;i<input.length();i++){

if(isVowel(input[i])){

vowel++;

}

else if (isAlphabet(input[i])){

consonant++;

}

else if(isNumber(input[i])){

digit++;

}

else{

specialChar++;

}

}

//Displaying the report

printReport(vowel,consonant,digit,specialChar);

return 0;

}

Ex: If the input file is:

Input

words.txt

Your output (end the following message with a newline)

Could not open file words.txt 

Step 2:

• Process each line in the file to get and print if a variable name is valid or not. For this purpose, you will need to modify printReport function (both definition and prototype) to print whether a given variable name is valid or not.

void printReport(string userText, int vowelCount, int consoCount, int digitCount, int specialCount)
{
    //implement the three rules of checking if the input word is a valid C++ variable or not    

   //you may copy the code below in your printReport() function
    if (isValid) {
        cout << "The variable name - " << userText <<  " - is valid." << endl;
    }
    else {
        cout << "The variable name - " << userText << " - is invalid." << endl;
    }

}

You must print the message in printReport() for each word in the input file (words.txt).

At this moment, your main() is going to have code that opens and reads contents of a file, does counting (vowels, consonants, digits, and special characters) and calls printReport(). Go ahead and run it to make sure that your code gives the correct output for a test string.

Step 3: Build a function called getCount() that takes a string parameter (for the inputText that is being analyzed) and four additional parameters corresponding to the count of each kind of character. These would be passed by reference and their value will be set by this function.

Prototype: void getCount(string userText, int& vowelCount, int& consoCount, int& digitCount, int& specialCount);.

Refactor your main() so that it only calls getCount and printReport by passing it appropriate arguments. At this stage, your main() should have code that opens and reads from a file and calls getCount() and printReport() for each word read from the input file. Run your code to make sure it works and gives the correct output for a test string.

getCount() function that does all the counting so as to reduce the code inside main() even further!

Homework # 3: Note: Please circle your answers when appropriate! 1) You have a sample of 11 flowers from pea plants. (a) Suppose 7 of them are white, and 4 of them are purple. If you line them up in a row, how many different arrangements can you get? Note: WWWWWWWPPPP is one arrangement, WPWPWPWPWWW is another arrangement, and so on. You do NOT want to actually list all possible arrangements - instead, use what you learned in class to calculate this. (b) Now suppose 4 of them are white and 7 of them are purple. How many different arrangements can you get? (c) How many arrangements do you have for 1 white and 10 purple? (d) How many arrangements do you have for 0 white and 11 purple? 2) In the U.S., about 8.5% of people are B+ for blood type. You take a sample of size 9. You're interested in people who are B+. Figure out the following probabilities: a) Pr{Y = 3} b) Pr{Y = 1} c) Pr{Y < 1} d) Pr{Y > 0} (hint - use (c) to answer this and make sure you know why this works) 3) Mendelian genetics predict that in Labrador retrievers (a type of dog), 75% should have black coat color if both parents are heterozygous (the rest are brown). You mate two parents and get a litter of 6 puppies. Calculate the following: a) The probability of 4 black puppies. b) The probability of 4 brown puppies. c) The probability that 50% of the puppies will be brown. (Comment: You do not need to know anything about genetics to solve this problem. If you're trying to do things like use punnet squares, you're doing things wrong) 4) Refer to problem 3. Calculate the probability of every possible outcome (hint: you need to make seven calculations (you already made three of them in problem 3)). 5) Let's do some R.... Suppose you have the following situation: You have a large jar of beans, 29% black, 71% white. You take a sample of 11 beans. a) Use R to figure out the probability for every single possible outcome. In other words, you need to calculate: Pr{0 black beans in 11 trials} Pr{1 black bean in 11 trials} . . etc. . Pr{11 black beans in 11 trials} b) Once you have this information, you need to plot a barplot that shows you what this distribution looks like. As you might guess, you'll need to use the binomial (in R - see below) to solve this problem. Make sure you present all your results (you should have a list of probabilities and the barplot). _________________________________________________________________________________________ Some R instructions to help you are on the next page. Instructions for copying graphs in/from R are also included at the end. For R problems: be prepared to sketch or list your results. You may be asked to show graphs to the class using the document camera at the front of the room (your recitation instructor will set this up for you). Note the following: NEVER, NEVER, hand in just an R printout: Clean it up and clearly label your answers. Make it obvious where everything is and what/where your conclusions/answers are. You will not do well if all you do is hand in a printout. Due in recitation the week of February 17th . R commands: Caution: Be careful copying and pasting commands into R. Some characters may not copy correctly and give you error messages. This is particularly true for quotes. R does not recognize quotes that look like “, only quotes that are straight like this: " . I tried to fix this below, but can’t guarantee I caught everything. Bean problem: Here's an example using a sample of 8 beans from a jar with 32% black beans. You should be able to modify the following as needed to answer question 6: For probabilities: You want probabilities for 0 through 8 beans. First we need to create y with 8 numbers: y <- c(0:8) This command says to give “y” the numbers 0 - 8 in sequence; technically “0:8” tells R it's a sequence of numbers, and the “c” out front means to combine all the numbers. The “c” isn't really needed (try it!) this time, but it is required in many similar situations so it's a good habit to get into to. Now we just “feed” our y into the binomial function to get our answers: p <- dbinom( y, size = 8, prob = .32) This should give you “p” with all the binomial probabilities (they'll be in order from 0 to 8; type “p” to get/see the probabilities) If you want to make it look nice, you can do: pr <- data.frame(y,p) pr to make it look even better, follow this with: print(pr,row.names = FALSE) The data.frame command combines the variables you list (in this case, y and p) into a single data set. Unfortunately if you then type “pr” R will insist on printing row names as well. If you want to get rid of the row names (they’re not needed), you need to use the print statement as given above. To get a barplot: To get a barplot, you simply do (see also the homework instructions from last week): barplot(p) This won't look very nice, so you should try to improve it: barplot(p,names.arg = y) Here “names.arg” is the variable that holds the labels you want to put on the x axis (remember we put the numbers 0 - 8 into y). Just try it - you'll see how it works. If you want to improve your graph even more, you can do (review the caution statement above if you have trouble copying and pasting this): barplot(p,names.arg = y, ylab = "frequency", xlab = "number of dark beans") Or even fancier: barplot(p,names.arg = y, ylab = "frequency", xlab = "number of dark beans", col = "blue") To copy/save graphs generated in R or RStudio: You're going to want to save your graphs or copy them into a word processor so that you can hand them in or refer to them during presentations. If you are using RStudio: (If you're given a choice of format to use as you follow these instructions (usually under Windows), choose “metafile”) Make sure the graph you want is visible in the graphics window. Click on “export” near the top of the plot window. Select “Copy Plot to Clipboard” The click on “Copy Plot” Open your favorite word processor and paste the graph into your document. Comment: copying graphs this way doesn't always give you the best looking graphs (particularly if you're using Linux). Saving the plot as a high resolution image and then inserting this into your document often gives better results. The details on how to do this are provided below - the following instructions work both with and without Rstudio. If for some strange reason you're not using RStudio or you want to do this just from the command line: Windows: In R, right click the graph, select “copy as metafile” (don't use bitmap), then open your favorite word processor and paste the graph. Mac OS: You should be able to copy the graph (make sure the graph window is active) from the menu, and then simply paste the graph into Word (or whatever word processor you use). If this doesn't work for some reason, the Linux instructions will work (they'll work with Windows as well). Linux: This is a bit complicated. A simple way to do it is to use the print screen key, but it'll look horrible. Here’s one example of getting good looking graphs: 1) generate the graph on-screen (just as usual) to make sure it looks right. 2) type “jpeg()” in the command line. There are actually several formats you can pick but jpeg is probably the easiest. 3) generate the graph again (make the graph again). You'll notice that nothing seems to happen. That's okay. It's writing the graph to a jpeg file. 4) now type “dev.off()” on the command line. 5) the graphics file should now be in your home directory. It'll have a name like “Rplotxxx.jpeg”, where xxx is some number. You can always sort by modification date in your file browser to find it quickly. 6) You should now be able to insert or copy the file into your text document (e.g. Word, LibreOffice, or whatever you're using). 7) The jpeg may not look terrific (it'll look a lot better than “print-screen”. You can increase the resolution by doing (in step 2 above)): jpeg(width = 1000,height = 1000) The jpeg command defaults 480 x 480, which isn't that great. You can also use the jpeg command to give it a filename that makes sense, if you want: jpeg(filename = "your-file-name",width = xxx, height = xxx)

As the senior accountant at Technology on Demand (TOD), which manufactures mobile technology such as flip phones, smartphones, notebooks, and smartwatches, you are often asked to prepare various financial analysis necessary for decision making. Michelle Dodd, the controller, asked you to evaluate whether a piece of factory equipment should be replaced or kept.

The old piece of factory equipment was purchased four years ago for $875,000. Over the last four years, TOD has allocated depreciation based on the straight-line method. The expected salvage value is $25,000. The current book value of the factory equipment is $425,000. The operating expenses total approximately $45,000 a year. It is estimated that the residual value (market value) of the old machine is $350,000.

The controller is contemplating whether to replace the piece of factory equipment. The replacement factory equipment would consist of a purchase price of $500,000, a useful life of eight years, salvage value of 30,000, and annual operating costs of $35,000.

In consideration of the background, prepare a memo in a Word document to submit to the controller. Your first paragraph would be an introduction paragraph of what the memo is about. Next, you will want to consider the equipment replacement decision. To add clarity to your discussion, you are to insert a table comparing the old equipment to the new equipment. In evaluating the “relevant” costs, what does your analysis show? Do you recommend that the equipment be replaced or kept ongoing for the next eight years? Why or why not?

Write a C++ program to create a text file. Your file should contain the following text:

Batch files are text files created by programmer.

The file is written in notepad.

Creating a text file and writing to it by using fstream: to write to a file, you need to open thew file as write mode. To do so, include a header filr to your program. Create an object of type fsrteam. Open the file as write mode.

Reading from a text file using fstream object: Besides including the fsrteam header file to your program, there are three points to remember to read from a batch file. First, to make sure there exists a file. Second, make sure the existing file is not emty. Third, open the file as a read mode.

To append text to the existing file: open and existing file as append mode which will append new information at the end of the file if the file is not emty.

Binary files: binary files are readable only by the compiler. A user would not be able to read a binary file.

Your program should read the text file and create the following output:

1. Find the number of words in each line and display it.

2. Find the number of lines and display it.

3. Find the total number of words in the file and display it.

4. Find the number of words that start with capital letters on each line and display it.

5. Find how many time word "file/files" are represented and display it.
