Chapter 2.1, Problem 12STQ
In the
that symbol = ‘7’;
System.out.printin((int) symbol);
Thus, (int) symbol does not produce the number corresponding to the digit in symbol. Can you write an expression that will work to produce the integer that intuitively corresponds to the digit in symbol, assuming that symbol contains one of the ten digits 0 through 9? (Hint: The digits do correspond to consecutive integers so if (int) ‘7’ is 55, then(int) ‘8’ is 56.)

So I am trying to find a code to let you enter an amount and it will output a coin amount with the least amount of numbers (ex. 220 coins =/= 220 pennies, instead 220 coins = 2 Dollars 2 Dimes) This is the code i have so far but it seems to not like my use of modula:
import math
change = int(input())dollars = change % 100quarters = math.remainder(dollars) % 25dimes = math.remainder(quarters) % 10nickels = math.remainder(dimes) % 5pennies = math.remainder(dimes) % 1dollars_modula = dollars // 1000
if dollars == 100: print('Dollar')
elif dollars == 200 or dollars == 300 or dollars == 400 or dollars == 500 or dollars == 600 or dollars == 700 or dollars == 800 or dollars == 900 or dollars == 1000: print('Dollar')
elif dollars <= dollars_modula: print('Dollars')
elif quarters == 25: print('Quarter') elif quarters == 25 or quarters == 50 or quarters == 75: print('Quarters')

Suppose you want to deposit a certain amount of money into a savings account, and thenleave it alone to draw interest for the next 10 years. At the end of 10 years, you would like tohave $10,000 in the account. How much do you need to deposit today to make that happen?You can use the following formula, which is known as the present value formula, to find out:The terms in the formula are as follows: [5 marks]• P is the present value, or the amount that you need to deposit today.• F is the future value that you want in the account. (In this case, F is $10,000.)• r is the annual interest rate.• n is the number of years that you plan to let the money sit in the account.Write a method named presentValue that performs this calculation. The method should accept the future value, annual interest rate, and number of years asarguments. It should return the present value, which is the amount that you need to deposit today.Demonstrate the method in a program that lets the user experiment with…

- Write a program named ConvertDate that converts a date entered by the user into another form. The user's input will have the form: month day, year The month will be one of the words January, February,... The letters in the month may be lowercase, uppercase, or any mixture of the two. The day is a one- or two-digit number. The year is any number of digits. There may be any number of spaces (1) before the month, (2) between the month and the day, (3) between the day and the year, and (4) after the year. You may assume that there is at least one space between the month and day and between the day and year. You may also assume that there is a comma after the day. The converted date must have the form day month year with one space between the day and month and between the month and year.

- You are given an integer variable dollarAmount that will have an integer value of ten or larger. It is a value that we want to display on a check. In order to write out the amount in words, the first step is to determine the digit from the ones position and from tens position. We are going to take those first steps! Declare an integer variable named ones and initialize it to the value in the ones position from dollarAmount. Declare an integer variable named tens and initialize it to the value in the tens position from dollarAmount. Declare an integer variable named hundreds and initialize it to the value in the hundreds position from dollarAmount. e.g. If dollarAmount = 1729,we would expect ones = 9, and tens = 2, and hundreds = 7. Sample input/output: Input Output 1729 Ones: 9 Tens: 2 Hundreds: 7 19452 Ones: 2 Tens: 5 Hundreds: 4 Output has been taken care of for you.arrow_forwardWrite a program that calculates the estimated hours and minutes for a trip given the number of miles traveled and the speed in miles per hour. Specifically, write a program that Welcomes the user to the Travel Time Calculator. Asks user for number of miles traveled(allow user to enter fractional values) Asks user for the speed in miles per hour (allow user to enter fractional values) Calculates the number of hours and minutes for the trip to the nearest integer value. Hint: You can use the built-in function round that rounds a given number to the rounded integer value. e.g. round(4) will return 4, round(4.125) will return 4, round(4.5) will return 4 and round (4.75) will return 5.
