I always find myself asking at the end of the month, “Where did all that money go?" I'm sure this isn't a problem I alone face. For this challenge, you'll write a program that creates a bar chart for easy comparison of weekly expenditures. The program should first ask for the number of categories for the expenditures and the weekly total expen- diture in each category, and then it should create the bar chart showing these expenditures.

use visual basic Depreciation to a Salvage Value of 0 . For tax purposes an item may be depreciated over a period of several years, n . With the straight-line method of depreciation , each year the item dpreciates by 1/nth of it original value. with the double-declining-balance method of depreciation, each year the item depreciate by 2/nths of its value at the beginning of that year.(In the final year it is depreciated by its value at the beginning of the year. ) Write a program that performs the following tasks:(a) Request a description of the item, the year of purchase, the cost of the item, the number of years to be depreciated (estimated life), and the method of depreciation. The method of depreciation should be chosen by clicking on one of two buttons.(b) Display a year- by-year description of the depreciation. See Fig. 6.15 .
IN C PROGRAMMING LANGUAGE A resistor is a circuit device designed to have a specific resistance value between its ends. Resistance values are expressed in ohms (Ω) or kilo-ohms (kΩ). Resistors are frequently marked with colored bands that encode their resistance values, as shown in the Figure. The first two bands are digits, and the third is a power-of-ten multiplier. The Table below shows the meanings of each band color. For example, if the first band is green, the second is black, and the third is orange, the resistor has a value of 50 × 103 Ω or 50 k Ω. The information in the Table can be stored in a C program as an array of strings. char COLOR_CODES[10][7] = {"black", "brown", "red", "orange", "yellow", "green", "blue", "violet", "gray", "white"}; Notice that “red” is COLOR_CODES[2] and has a digit value of 2 and a multiplier value of 102. In general, COLOR_CODES[n] has digit value n and multiplier value 10n. Write a program that prompts for the colors…

You want to create a program to enroll in classes. You've narrowed the class list down to just a few classes that computer science students might need. In your program, first the user will select a department and the program will tell them what classes are available from that department. Then the user picks a class, and the program will tell them what sections are available. After the user picks a section, the program will print a success message. The departments, classes and sections are as follows: Sample run: Select a department: (1)Computer Science (2)Math (3)Science 1 Select a class: (1)Starting Computing (2)Data Structures (3)Algorithms 3 Select a section: (1)Section 102 (2)Section 202 1 You've been enrolled in Section 102 of Algorithms! The user should input an integer in the range of the choices you give them. For example, a user cannot input 3 if you only present 2 choices.Ensure you are doing input validation. Your program should output Please enter a valid input. if the…
In the following procedure, the parameter age represents a person's age. The procedure is intended to return the name of the age group associated with age. People who are under 18 are considered minors, people who are 65 and older are considered senior citizens, and all other people are considered adults. The procedure does not work as intended.

In various applications, you are often asked to compute the mean and standard deviation of data. The mean is simply the average of the numbers. The standard deviation is a statistic that tells you how tightly all the various data are clustered around the mean in a set of data. For example, what is the average age of the students in a class? How close are the ages? If all the students are the same age, the deviation is 0. Write a program that prompts the user to enter any number of values into a double array, and then calculates and displays the mean and standard deviations of these numbers using the following formulas: (z - mean) z+z3+ *** +zn deviation = mean = n-1 Required Methods You must write your program so that the following methods are defined/implemented and used (called): • /* Compute the deviation of double values */ public static double deviation (double[] x) • /* Compute the mean of an array of double values */ public static double mean (double[] x) Sample Run (user input…

Please do this in Python Programming Scenario As you probably know, Sudoku is a number-placing puzzle played on a 9x9 board. The player has to fill the board in a very specific way: each row of the board must contain all digits from 0 to 9 (the order doesn't matter) each column of the board must contain all digits from 0 to 9 (again, the order doesn't matter) each of the nine 3x3 "tiles" (we will name them "sub-squares") of the table must contain all digits from 0 to 9. If you need more details, you can find them here. Your task is to write a program which: reads 9 rows of the Sudoku, each containing 9 digits (check carefully if the data entered are valid) outputs Yes if the Sudoku is valid, and No otherwise. Test your code using the data we've provided. Test data Sample input: 295743861 431865927 876192543 387459216 612387495 549216738 763524189 928671354 154938672 Sample output: Yes Sample input: 195743862 431865927 876192543 387459216 612387495 549216738 763524189 928671354…
A video player plays a game in which the character competes in a hurdle race. Hurdles are of varying heights, and the characters have a maximum height they can jump. There is a magic potion they can take that will increase their maximum jump height by unit for each dose. How many doses of the potion must the character take to be able to jump all of the hurdles. If the character can already clear all of the hurdles, return . Example The character can jump unit high initially and must take doses of potion to be able to jump all of the hurdles. Function Description Complete the hurdleRace function in the editor below. hurdleRace has the following parameter(s): int k: the height the character can jump naturally int height[n]: the heights of each hurdle Returns int: the minimum number of doses required, always or more Input Format The first line contains two space-separated integers and , the number of hurdles and the maximum height the character can jump naturally.The…
The Goal: Like the title suggests, this project involves writing a program that simulates rolling dice. When the program runs, it will randomly choose a number between 1 and 6. (Or whatever other integer you prefer — the number of sides on the die is up to you.) The program will print what that number is. It should then ask you if you’d like to roll again. For this project, you’ll need to set the min and max number that your dice can produce. For the average die, that means a minimum of 1 and a maximum of 6. You’ll also want a function that randomly grabs a number within that range and prints it. Concepts to keep in mind: Random, Integer, Print, While Loops
Grocery List. When shopping for groceries, it's helpful to know how much it's going to cost you in advance - this helps you avoid an embarrassing situation in the check-out line. For this assignment, you're going to write a simple program that asks you for the name, quantity, and price of two grocery store items. It will then generate a grocery list for you, complete with the total price. (Later in the semester, we'll learn how to make a program that can create much larger lists, but we'll start small here). Call the file Assignment1B (with a file extension of .cpp, .cs or .java) Sample Output: What're you buying? Ice Cream How many? 2 What do they cost? 2.25 What else're you buying? Celery How many? 5 What do they cost? 1.74 Your list: Ice Cream (2) $2.25 ($4.50 total) Celery (5) $1.74 ($8.7 total) Total Cost: $14.2 using Java programming
