Write Java a program that will record the purchases made at a store. For each purchase, read from the keyboard an item's name, unit price, and the quantity. Compute the cost of the purchase (unit price times quantity). Write all these data to a text file. Name the file any name you like (Suggestion: purchase.txt) Display the current total cost on the screen. After all items have been entered, write the total cost to the screen. Since we want to remember all purchases made, you should append new data to the end of the file.

Write a program, and store it in a file called Travel Expenses.xlsm, that does the following: (a) It asks for a person’s first name and stores it in firstName; (b) it asks for a person’s last name and stores it in lastName; (c) it asks for the number of miles the person traveled on a recent trip and stores it in nMiles; (d) it asks for the average miles per gallon the person got on the trip and stores it in milesPer- Gallon; (e) it asks for the average price per gallon paid for gas on the trip and stores it in avgPrice; (f) it calculates the cost of the trip and stores it in tripCost; and (g) it displays a message such as "Bob Jones traveled 800 miles, got 31.3 miles per gallon on average, paid 3ドル.49 per gallon on average, and paid a total of 89ドル.20 for gas." Make sure there is an Option Explicit line at the top of the module and that you declare all of your variables appropriately.

create a Python program that: Opens a file and reads the contents of the following file trips.txtDownload trips.txt The file contains several lines of data, with each data item separated by commas. The data is: A trip date The amount of fuel used on the trip The number of miles traveled on the trip For each of the lines of data in the file, separate the data items and put them in appropriate variables The file contents are in the form of strings, so you must convert the numbers in the data into the proper type Create a function that calculates the fuel mileage achieved on each trip Pass the appropriate data to this function Place this function in a separate module Call the function as needed and have the function return the calculated fuel mileage Create a function that displays the following items on a single line, and place the function in the same module as the previous function. Pass the appropriate data to this function Trip data Amount of fuel used Numbers of...

Python programming language Write a program that asks the user for a number. Write the number to a file called total.txt. Then ask the user for a second number. Write the new number on line 2 with the total for both numbers next to it separated by a comma. Then ask the user for a third number and do the same. Keep asking for numbers until the person puts in a zero to terminate the program. Close the file. Be sure to use at least 2 functions [main() and total_numbers(number, total)]. Put all inputs and outputs into the main function, with all calculations into the total_numbers function. Give me a number: 13 Give me another number: 14 14 + 13 = 27 Give me another number: 3 3 + 27 = 30 Give me another number: 4 4 + 30 = 34 Give me another number (0 for quit): 0 Your total is 34. Write a program that displays the lines from the total.txt file in the following output. Use a try catch phrase to check for errors. Use only one function for this portion [main()]. 13 14, 27 3,...

Write a program to draw a quiz score histogram. Your program shouldread data from a file. Each line of the file contains a number in the range0-10. Your program must count the number of occurrences of each scoreand then draw a vertical bar chart with a bar for each possible score (0-10) with a height corresponding to the count of that score. For example,if 15 students got an 8, then the height of the bar for 8 should be 15.Hint: Use a list that stores the count for each possible score. An examplehistogram is shown below: o o D D0 1 2 3 4 5 6 7 8 9 10

JAVA PROGRAM Chapter 4. Homework Assignment (read instructions carefully) Write a program that asks the user for the name of a file.

Python Create a program that reads the file (create a paragraph in a file). It should analyze each character of the file. For output, it should produce a well-formatted table indicating: The total number of printable characters The total number of capital letters The total number of lowercase letters The total number of numbers The total number of sentences (which end in a period) The total number of paragraphs (which end in a newline) Since the lab is an exercise in strings, you must use at least TWO different string methods to required information. And each stastic will need its own function.

Need help writing this java code, it has three objectives: to process strings to compare, search, sort, and verify location of specific pattern to output result via interface Description Write a Java program to read a text file (command line input for file name), process the text file and perform the following. Print the total number of words in the file. (When using java_test.txt, I calculate the number of words, including number, as 254.) Print the total number of different words (case sensitive, meaning "We" and "we" are two different words) in the file. (When using java_test.txt, I calculate the number of different words, including number, as 168.) Print all words in ascending order (based on the ASCII code) without duplication. Write a pattern match method to find the location(s) of a specific word. This method should return all line number(s) and location(s) of the word(s) found in the file. Print all line(s) with line number(s) where the word is found by invoking the method...

just do the first step. and the program should be in python and includ as many different functions as possible .
