Write a program that reads a file and find out the total uppercase, lowercase, whitespaces and digits occurred in the file.
1. Write a program that opens an output file with the filename my_name.txt, writes your name to the file, then closes the file.
2. Write a program that opens the my_name.txt file that was created by the program in problem 1, reads your name from the file, displays the name on the screen, then closes the file. Write code that does the following: opens an output file with the filename number_list.
please use c#
Be sure to thoroughly document your coding, explaining what you did and why you did it. Comments should explain what your code does (each line or each block of lines...etc.)

- 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.

If they are not, the script should output "No", followed by the first lines of each file that differ from each other. The input loop should read and compare lines from each file, including whitespace and punctuation. The loop should break as soon as a pair of different lines is found.

Here is a typical coding pattern for processing each line of a file in turn: Open the file for reading. Use a for loop to iterate over the lines of text, executing a block of one or more statements to process each line. Close the file. Finish processing (print, return, etc.) if needed NOTE: You will need to use this pattern, or some variation of it, to solve the remaining coding problems in this assignment. As the following for loop iterates through each line of the file, the loop variable (`line`) represents the current line of the file as a string of characters. myFile = open("someTextFile.txt", "r") for line in myFile: do something on each iteration do a second thing on each iteration etc... myFile.close() PROBLEM: Read a string from standard input using python.

- Task: Loading data from files This exercise will require you to load some information from files and use it in your program. scene.txt contains a description of a series of shapes and colours to draw. You need to write code to read in the file data and draw the requested shapes in the correct colour. Each line in scene.txt will contain one of the following starting keywords followed by some data: COLOUR followed by 3 values: R, G, B CIRCLE followed by 3 values: X, Y, RADIUS RECT Followed by 4 values: X, Y, W, H LINE Followed by 4 values: X1, Y1, X2, Y2 CIRCLES are defined from the center. RECT's are defined from the top left. All values are space separated, and you can assume all input is correct (no errors). Please solve this program to draw the scene. I can't upload the file scene.txt, so I decide to screenshot a file for you. Subject: Java Programmingarrow_forward1) Write a Java program to read a CSV (Comma separated values) text file. The text file will contain comma separated values in each line. There will be multiple lines with each line containing the same number of values. Ask the user to enter the path for the CSV file for reading the file. After reading the data from the file output the data to the console (one line at a time) with the data in each line in properly aligned columns. Then write the data to a serialized file called "credit.ser" to the local project folder . 2) In the second program, read the serialized file and output the data in columns to the console (one line at a time) with the data in each line in properly aligned columns.arrow_forwardProgram 5: Word Frequencies (Concordance) Use a text editor to create a text file (ex: myPaper.txt) It should contain at least 2 paragraphs with around 200 or more words. Write a Python program (HW19.py) that asks the user to provide the name of the text file. Be SURE to check that it exists!Do NOT hard-code the name of the file! Use the entry provided by the user! read from the text file NOTE: (write your program so that it ONLY works if it reads from the file specified by the user). Your program will produce a dictionary of words with the number of times each occurs. It maps a word to the number of times the word occurs Key: a word Value: the number of times the word occurs in the text. The report should be an ALPHABETIZED output table, listing the word and the number of occurrences.

- <<Write in Java>> - Challenge 7 File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. - Challenge 8 Write a program that decrypts the file produced by the program in Programming Challenge 7. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another filearrow_forwardInput. test.txt 3 1 0 Output File "example.txt", line 2 (name=input("Enter the input file name:") ^ SyntaxError: invalid syntax .test.txt 3 1 0arrow_forward(True/False): A file’s directory entry contains the file’s starting sector number.arrow_forward
