In C++ PLEASE  Use the text file from Chapter 12, forChap12.txt. SEE BELOW  Write a program that opens a specified text file then displays a list of all the unique words found in the file.  Addition to the text book specifications,  print the total of unique words in the file. Text File = forChap12.txt No one is unaware of the name of that famous English shipowner, Cunard. In 1840 this shrewd industrialist founded a postal service between Liverpool and Halifax, featuring three wooden ships with 400-horsepower paddle wheels and a burden of 1,162 metric tons. Eight years later, the company's assets were increased by four 650-horsepower ships at 1,820 metric tons, and in two more years, by two other vessels of still greater power and tonnage. In 1853 the Cunard Co., whose mail-carrying charter had just been renewed, successively added to its assets the Arabia, the Persia, the China, the Scotia, the Java, and the Russia, all ships of top speed and, after the Great Eastern, the biggest ever…

Design a program that reads a file called sales.txt containing the following data: Jane, 215.5,445.5,910.0 John, 825.0,250.5,675.0 Bill,0.0,999.15 Each line has a employee's name and their weekly sales totals all separated by commas. Some employees have taken vacation some weeks so no numbers are captured for those weeks. Create a function that takes a list of floats and returns the average value for those numbers. After reading the information from the file, use a for loop to calculate the sales average using your new average function for each employee and display the following output to the screen. Jane, average sales: 523.67 John, average sales: 583.50 Bill, average sales: 499.56

PLEASE COMMENT CODE In a python program, create a new file and call it “ tracking”. Write to it four lines each contains information about an order like this: 1-00654-021 Dell charger Toronto-WEST 99-49-ZAD011-76540-022 ASUS battery Milton-EAST 34-56-CBH561-09239-026 HP HD Scarborough-NORTH 12-98-AZC451-12349-029 Mac FD North York-LAWRENCE 34-49-ZWL01Add the file two more lines:    1-34567-055 Lenovo SSD Milton-ON 34-09-MT04    1-90432-091 Lenovo battery Oakville-ON 78-KL98 Define a function that searches for a brand (e.g. Dell, ASUS, etc.). Test the function in your program.

C++ Code dynamicarray.h and dynamicarray.cpp

C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found.  Attached is the first lines of the .txt file

Instructions: You are strictly not allowed to use anything other than pointers and dynamic memory. One function should perform one functionality only.   Task 1 Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task. Row wise Sum Column wise Sum Diagonal wise Sum   Example   data.txt 4 5 1.6 10.2 33.7 99 20.5 3 44 50 96.1 2 8 9 4 74 50 99 19.1   Output: Sum row wise: 165, 191, 17, 242.1 Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5 Sum diagonal wise: Not Possible   Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.

C++ Code:  Write a program that finds word differences between two sentences. The input begins with an integer indicating the number of words in each sentence. The next input line is the first sentence and the following input line is the second sentence. Assume that the two sentences have the same number of words and no more than 20 words each. The program displays word pairs that differ between the two sentences. One pair is displayed per line. Ex: If the input is: 6 Smaller cars get better gas mileage Tiny cars get great fuel economy then the output is: Smaller Tiny better great gas fuel mileage economy Add a function named ReadSentences to read the input sentences into two string vectors. void ReadSentences(vector<string>& sentence1Words, vector<string>& sentence2Words, int wordCount) main() already contains code to read the word count and call ReadSentences(). Complete main() to display differing word pairs.
