Problem: Write a program that accept a character whether a capital or NOT and displays its corresponding number. Filename: character.java
In Python do the following: Writing to Files: write code to write to a file called ‘writefile.txt’To write in a file we first have to open the file. That is what the first line should do so that Pythoncreates a file object to represent the file, and give the object the name f (variable). We use this variableto refer to the file. To write to the file, use the print statement with the optional file argument thatspecifies the file to write to. When done writing, close the file to make sure all the changes are saved.Remember, if writefile.txt already exists, its contents will be overwritten.
Python please: Given a text file named RandomTextFile.txt that contains newline characters, write a program that removes all the newline characters from the file. Your program should use the filename as input, and the output file should use the same filename as the original. Use the attached file RandomTextFile.txt to help you write and test your program. It contains the following text: Python is an interpreted language and the python interpreter is a computer program that executes code written in the python programming language. The python interactive interpreter is useful for simple operations or programs consisting of only a few lines. For more lines, a programmer can write Python code in a file, and then provide that file to the interpreter. For normal development a programmer installs python as an application on a local computer. Macintosh and Linux operating systems usually include python, while Windows does not. Programmers can download the latest version of python for free from…
C#- Given a text file, refer to the example and write a program (console application) that counts the number of words that end with the letter "t" or "e" (not case sensitive). We’ll say that a "t" or "e" is at the end of a word if there is not an alphabetic letter immediately following it. The program should output the resulting count.
Character Analysis Create a source code text file and save it as named text.txt. Write a program that reads the file's contents and determines the following: - The number of uppercase letters in the file. - The number of lowercase letters in the file. - The number of digits in the file. - The number of whitespace characters in the file. * Note: Please be sure to use the Python program when creating the program. Thanks!

Question #3: Write a C program that reads integer numbers from a data file named numbers.txt, one-by-one. For each number, the program computes and displays the factorial using: a user-defined function named factorial that you should declare and define in the program a user-defined function named factorial_ recursion that you should declare and define in the program The program writes the number and its factorial to a data file Results.txt. Hint: Function factorial has one argument: n (int) and returns n!. It uses for structure to compute n! Function power_ recursion is a recursive function that has one argument: n (int) and returns n!. It computes n! recursively Below are examples of the input and output files 3 3! = 6 5! = 120 7 7! = 5040 10 10! = 3628800 numbers.txt Results.txt #include…
Python Problem Description: Kevin is a freelance video producer who makes TV commercials for local businesses. When he makes a commercial, he usually films several short videos. Later, he puts these short videos together to make the final commercial. He has asked you to write the following two programs. A program that allows him to enter the running time (in seconds) of each short video in a project. The running times are saved to a file. A successful test run for this program would be as shown below: A program that reads the contents of the file, displays the running times, and then displays the total running time of all the segments. A successful test run for this program would be as shown below:
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.
Q2: Write a complete C++ program that reads the contents of the text file "mydata.txt", word by word, and appends them to the end of text file "myoutput.txt" . The main function calculates and prints the number of characters read and copied between the files.
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 - Next Birthdate In this task, we will write a program that reads birthdate data from a given CSV file, and given the current date, determines which person's birthday will be celebrated next. Create a function with the following signature: nextBirthdate(filename, date) filename: parameter, which represents the CSV filename. date: parameter, which represents the current date. The function should open the CSV file, read the birthdate data, and determine which person's birthday will be celebrated next, given the current date. The name of the person should be returned. In other words, given a date, find the person whose birthday is next. Sample Run birthdates.csv Draven Brock, 01/21/1952 Easton Mclean, 09/02/1954 Destiny Pacheco, 10/10/1958 Ariella Wood, 12/20/1961 Keely Sanders, 08/03/1985 Bryan Sloan,04/06/1986 Shannon Brewer, 05/11/1986 Julianne Farrell,01/29/2000 Makhi Weeks, 03/20/2000 Lucian Fields, 08/02/2018 Function Call nextBirthdate("birthdates.csv", "01/01/2022") Output…
Using C++, create a program that reads integers from the file named "123456" and performs the following actions: Define a function named "calculateFileStats" that reads all the integers from the file and displays the following on the console: -The total sum of all numbers in the file -The minimum value of the numbers in the file -The maximum value of the numbers in the file -The average value with 2 decimal places. If the program fails to access the file, display an error message to the user and terminate the program. Close the file once you have finished reading it. Call the function "calculateFileStats" in main. Note: I did not forget to attach an input file. Use your own input code. I am interested in your code. sample run: Total: 30309 Minimum: 1 Maximum: 10 Average: 5.58
