Exercise #2 Frequency Analysis: One of the oldest approaches to breaking a code is to perform a frequency count of letters. Write a C++ program to perform a frequency count by reading the text from a file (code.txt). Your program should output how many A's are there in the text, how many B's are there, and so on. Note that the program will not make any distinction between uppercase and lowercase letters. It will output the results to the screen and in a text file (count.txt) Sample output (for code.txt): A: 3 B: 3 C: 23 D: 13 E: 41 F: 4 G: 9 H: 15 1:44 J: 1 K: 0 L: 7 M: 9 N: 33 0:16

Good day/evening , C++ help needed. I am reading in two integers from a file. For example my input.txt file has the integers : “4–5” I am able to open the file and store the first value (4) into variable n but I can't store the second integer value (5) into variable m, I think the computer reads the dash as the next integer instead of the actual integer which is 5, how can I create a code that ignores the dash when searching for the integer in the input.txt? Thank you
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…
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

Write a C++ program using loops for a number guessing game. The program generates and stores a random number and prompts a user to guess the number. If user guess is less than the number, display “Sorry, guess is too low”, if user guess is greater than the number, display “Sorry, guess is too high”. If user guesses the right number, display “Congratulations, you have guessed the number”, and number of users tries to guess a number. The program should keep on taking a user input, until user guesses the number. Sample Output 1 (Number 50): Enter a number to guess: 50 “Congratulations, you have guessed the number” in first try. Sample Output 2 (Number 50): Enter a number to guess: 25 “Sorry, guess is too low” Enter a number to guess: 60 “Sorry, guess is too high” Enter a number to guess: 50 “Congratulations, you have guessed the number in 3 tries”, 2.12.0.0
