Let's modify the program from this section so that the user can supply the interest rate. For very small interest rates, it may take a very long time for the balance to double.

Suppose you can buy chocolate bars from a vending machine for $1 each.Inside every chocolate bar is a coupon. You can redeem 7 coupons for 1chocolate bar from the machine.For example, if you have $20, you can initially buy 20 chocolate bars.This gives you 20 coupons. You can redeem 14 coupons for 2 additionalchocolate bars. These 2 chocolate bars have 2 more coupons, so you now have atotal of 8 coupons. This gives you enough to redeem for 1 final chocolate bar.Write a recursive function that would accept the amount of dollars andcoupons as its parameters and output the total number of chocolate bars thatcan be bought (including those redeemed via coupons).Write a test program in C++that would allow the user to enter amount of dollarsand then use the recursive function to compute the number of chocolate barsthe user can buy, and output the number to the screen.
Write a program that reads HAND_SIZE cards from the user, then analyzes the cards and prints out the type of poker hand that they represent. (HAND_SIZE will be a global constant, typically 5, but your program must still work if it is set to something other than 5.) Poker hands are categorized according to the following hand-types: Straight flush, four of a kind, full house, straight, flush, three of a kind, two pairs, pair, high card. To simplify the program we will ignore card suits, and face cards. The values that the user inputs will be integer values from LOWEST_NUM to HIGHEST_NUM. (These will be global constants. We'll use LOWEST_NUM = 2 and HIGHEST_NUM = 9, but your program must work if these are set to something different.) When your program runs it should start by collecting HAND_SIZE integer values from the user and placing the integers into an array that has HAND_SIZE elements. It might look like this: Enter 5 numeric cards, no face cards. Use 2 - 9. Card 1: 8 Card 2: 7 Card…

Implement a program that calculates the bill of a sandwich stand. The program should ask theuser to enter the quantity of each of the items. Then compute 13% GST on the total amountand generate a bill with items, their quantity along with price of each item and the total(inclusive GST). The stand has the following items:- Petti for $2.50- Drink for $1.25- Extra cheese topping for $1.25
What is the probability that in a classroom of x people, at least 2 will be born on the same day of the year (ignore leap year)? Use a Monte Carlo Simulation and a frequency table to write a program that calculates this probability, where the number of people (x) in the simulated class is given by the user. The probability for a class of size 23, should be right around 50%. NO language of "break" or "true" please! PLEASE USE THE OUTLINE GIVEN BELOW TO WRITE THE CODE: # What is the probability that in a classroom of x people, at least 2 will be born on the same day of the year (ignore leap year)?# I have given you the skeleton and some of the code... you complete it using a frequency table!# Note: In a classroom of only 23 people, the probability is about 50.7% !# Try first with 10000 trials and then try with 100000 trials.

When you use a mortgage to purchase a home, the lending institution effectively owns the home. You buy back part ownership in the home with each monthly payment. The part you have bought back is your equity in the home. If the mortgage amount is P dollars, the monthly interest rate is r as a decimal, and the term of the mortgage is t months, then your equity after k payments is E(k) = P((1 + r)k − 1) (1 + r)t − 1 dollars. In this exercise, assume that the mortgage amount is $200,000, the APR is 6% so r = .06/12 and the term of the loan is 30 years (360 months). (a) Find a formula for the equity. (b) Make a graph of the equity over 360 months, the term of the loan. (c) Does the graph show that you have half-ownership in the home halfway through the term of the mortgage? Halfway through the term of the mortgage corresponds to k1 = _______ payments. From the graph, we see that E(k1) is ________ half of the mortgage amount, so we _______ have half-ownership in the home…
Write a program that asks a user to enter a first name, a last name, and a year, andconstruct an account ID in the format of:firstname.lastnameYYwhere the field “firstname” is user’s first name allowing no more than (first) five letters;the field “lastname” is user’s last name allowing no more than (first) six letters; and thefiled “YY” is the lower two digits of the year. For example:first name entered: Michaellast name entered: Richmondyear entered: 1985 the constructed account ID will be: Micha.Richmo85
On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved by executingcout << fixed << setprecision(2); once before all other cout statements. Ex: If the input is: 440.0 (which is the A key near the middle of a piano keyboard), the output is: 440.00 466.16 493.88 523.25 554.37 Note: Use one statement to compute r = 2(1/12) using the pow function (remember to include the cmath library). Then use that r in subsequent statements that use the formula fn = f0 * rn with n being 1, 2, 3, and finally 4.

In Java, is there a simple way of doing this without having to use so many If statements? please explain A client wants to purchase drinks for an event they are arranging. Write a program that asks them how much money they have to spend and whether alcohol would be allowed at the event. Then show them their choices from the following list, but 1) only show drinks that they can afford to buy at least 1 of, 2) only show alcoholic drinks if they are allowed at the event, and 3) show how many of each drink they could afford. If the user enters an invalid or negative value for their budget or an invalid response for whether alcohol is allowed, it should indicate an error and let the user try again. The possible drink choices are: Bottle of Water: $0.50 Soda: $1.50 Tea: $3.00 Beer (alcoholic): $5.00 Wine (alcoholic): $20.00
