Question 3: Write a program that reads a file of text and displays the number of words in that file. The filename is entered by the user. A Word is defined to be any number of consecutive letters (a...z, A...Z) only. Words are separated from each other by spaces (* ') and/or commas (',') and/or semicolon (*; and/or full stop (:'). Your program should write the words in the file "output.txt" along with the total word count. As shown below. file.txt Abcdef, ;; gfdyire hsdhfkdsf, , ;; , dkjfkjdljkfldj. .. mnbsdT .. ;; nbmxhs , a djks. output.txt Abcdef gfdyire hsdhfkdsf dkjfkjdljkfldj mnbsdT nbmxhs a djks Total count of words are = 8

Specifically if a is an integer is countTotalDigits (a):// Returns total digits in integer // Function to count & print even digitS countEvens (a) ; countodds (a) ; // Function to count & print odd digits countDigits (a) ; // Function to count & print digits with stars
Can you help me write a C++ Program that does the following: Create a program that reads a file containing a list of songs andprints the songs to the screen one at a time. After each song is printed,except for the last song, the program asks the user to press enter for more.After the last song, the program should say that this was the last song andquit. If there were no songs in the file to begin with, the program shouldsay that there are no songs to show and quit.The program should begin by asking the user for the name of the input file.Each song consists of a title, artist and year.In the file, each song is given on three consecutive lines.Create this program using the latest version of the class Song you created. The latest version of the class song I created is below: #include <iostream>#include <string>using namespace std;class Song {private: string Title; string Artist; int Year;public: Song() : Title("invalid"), Artist("invalid"), Year(-1) {} Song(const string…
The objective of this problem is to show that you can write a program that reads a text file and uses string methods to manipulate the text. File cart.txt contains shopping cart type data from golfsmith.com representing the gifts you have purchased for your dad for this past Fathers Day. Good for you. You have been very generous! The first item in each row of the file is the part number, the second the quantity, the third the price and the fourth the description. Your program will read the file line by line and compute the total cost of all of the items in the list. You will then display a message that looks like this, assuming the cost of each item adds up to 168.42: Here's what your output should look like: The total price for the awesome Fathers Day gifts you bought is $168.42. The shopping cart can be found here: cart.txt. Right click on the link and save the file to the folder where you have your Python files.
PYTHON: I need to get the avg statement out of the loop so that the output prints correctly. Any suggestions. Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam…
Computer Science C++ Create a text file "input.txt" with a certain amount of integers (you decide how many). Write a program that reads these numbers from the file, adds them, and when you have reached the end of the file, calculates the average of these numbers. Print a message and the average to the console. Code this program twice, demonstrating the two methods to detect the end of the file, part A: reading a value from Instream and storing it (boolean expression) in the while loop part B: using the eof() member function
C++ . Write a program that finds the number of times a specific word appears in a text file. The program should accept the following inputs from the user: The word that you are looking for. The word length should be 3 or more otherwise the program should print Too short. The word should not have a space character. The name of the file that contains the text The type of the search 0 for case senstive search 1 for case insensitive search For any other input the program should output Invalid Note that the word should be preceded and succeeded by spaces.
