Answer: Printing of documents was initially accomplished using IBM Selectric typewriters modified for ASCII-character input. These were later replaced by application-specific daisy wheel printers, first developed by Diablo, which became a Xerox company, and later by Qume.

Implement the above in c++, you will write a test program named create_and_test_hash.cc . Your programs should run from the terminal like so:
./create_and_test_hash should be "quadratic" for quadratic probing, "linear" for linear probing, and "double" for double hashing. For example, you can write on the terminal:
./create_and_test_hash words.txt query_words.txt quadratic You can use the provided makefile in order to compile and test your code. Resources have been posted on how to use makefiles. For double hashing, the format will be slightly different, namely as follows:
./create_and_test_hash words.txt query_words.txt double The R value should be used in your implementation of the double hashing technique discussed in class and described in the textbook: hash2 (x) = R – (x mod R). Q1. Part 1 (15 points) Modify the code provided, for quadratic and linear probing and test create_and_test_hash. Do NOT write any functionality inside the main() function within create_and_test_hash.cc. Write all functionality inside the testWrapperFunction() within that file. We will be using our own main, directly calling testWrapperFunction().This wrapper function is passed all the command line arguments as you would normally have in a main. You will print the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 2 (20 points) Write code to implement double_hashing.h, and test using create_and_test_hash. This will be a variation on quadratic probing. The difference will lie in the function FindPos(), that has to now provide probes using a different strategy. As the second hash function, use the one discussed in class and found in the textbook hash2 (x) = R – (x mod R). We will test your code with our own R values. Further, please specify which R values you used for testing your program inside your README. Remember to NOT have any functionality inside the main() of create_and_test_hash.cc
You will print the current R value, the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 3 (35 points) Now you are ready to implement a spell checker by using a linear or quadratic or double hashing algorithm. Given a document, your program should output all of the correctly spelled words, labeled as such, and all of the misspelled words. For each misspelled word you should provide a list of candidate corrections from the dictionary, that can be formed by applying one of the following rules to the misspelled word: a) Adding one character in any possible position b) Removing one character from the word c) Swapping adjacent characters in the word Your program should run as follows: ./spell_check
You will be provided with a small document named document1_short.txt, document_1.txt, and a dictionary file with approximately 100k words named wordsEN.txt. As an example, your spell checker should correct the following mistakes. comlete -> complete (case a) deciasion -> decision (case b) lwa -> law (case c)
Correct any word that does not exist in the dictionary file provided, (even if it is correct in the English language). Some hints: 1. Note that the dictionary we provide is a subset of the actual English dictionary, as long as your spell check is logical you will get the grade. For instance, the letter "i" is not in the dictionary and the correction could be "in", "if" or even "hi". This is an acceptable output. 2. Also, if "Editor’s" is corrected to "editors" that is ok. (case B, remove character) 3. We suggest all punctuation at the beginning and end be removed and for all words convert the letters to lower case (for e.g. Hello! is replaced with hello, before the spell checking itself).
Do NOT write any functionality inside the main() function within spell_check.cc. Write all functionality inside the testSpellingWrapper() within that file. We will be using our own main, directly calling testSpellingWrapper(). This wrapper function is passed all the command line arguments as you would normally have in a main

This question is way to long I don’t even understand what your asking

You are on a team of developers writing a new teacher tool. The students names are stored in a 2D array called “seatingChart”. As part of the tool, a teacher can enter a list of names and the tool well return the number of students in the class found with names that matching provided list. For this problem you will be completing the ClassRoom class in the problem below. Your job is to complete the numberOfStudents found method. This method accepts an array of Strings that contain names and returns the quantity of students with those names. For example:
Assume that a ClassRoom object named “computerScience” has been constructed and the seating chart contains the following names:


“Clarence”, “Florence”, “Ora”


“Bessie”, “Mabel”, “Milton”


“Ora”, “Cornelius”, “Adam”


When the following code executes:


String[] names = {"Clarence", "Ora", "Mr. Underwood"};

int namesFound = computerScience.numberOfStudents(names);

The contents of namesFound is 3 because Clarence is found once, Ora is found twice, and Mr. Underwood is not found at all. The total found would be 3.


Complete the numberOfStudents method

public class ClassRoom

{


private String[][] seatingChart;


//initializes the ClassRoom field seatingChart

public ClassRoom(String[][] s){

seatingChart = s;

}



//Precondition: the array of names will contain at least 1 name that may or may not be in the list

// the seating chart will be populated

//Postcondition: the method returns the number of names found in the seating chart



//TODO: Write the numberOfStudents method


public int numberOfStudents(String[] names){





}


public static void main(String[] args)

{

//DO NOT ENTER CODE HERE

//CHECK THE ACTUAL COLUMN FOR YOUR OUTPUT

System.out.println("Look in the Actual Column to see your results");

}

}
