Question

MATLAB CODE

Let’s say you need to write a small script that takes in the total amount of money entered, and a cost, and returns the correct change in quarters/dimes/nickels/pennies.

• Initialize counter variables for quarters, dimes, nickels and pennies to 0. Counter variables are used to keep track of how many of each coin are to be returned.
• Calculate the amount of change to be given using the ‘total’ and ‘cost’ variables.
• While there is still change to be given, find the largest coin that can be returned, increment the coin’s counter, and subtract the coin value from the amount of change to be given.
• Display the total change, as well as how many of each coin are being returned.

PREVIOUS CODE FOR THIS

function value = get_coin_value(coin)

%Set value to be the correct number based on coin.

%For example, if coin == 'q', value = 25

if coin == 'q'

value = 25;

elseif coin == 'd'

value = 10;

elseif coin == 'n'

value = 5;

elseif coin == 'p'

value = 1;

else

value = 0;

end

function total = insert_coins

%your code here

total = 0;

%Loop to keep asking user for coin till total is less than 115 cents

while(total<115)

coin = input('Enter q for quarter, d for dime, n for nickel,p for penny:','s');

total = total + get_coin_value(coin);

end

disp("Your NAU power juice has been dispensed")

end

Answer 1

classdef MyClass < handle properties
publicProp = 1;
end

end
methods
function obj = MyClass(value)
obj.privateProp = value;
end
function publicMethod(obj,value)
obj.privateMethod(value);
end
function res = calculateSomeValue(obj)
res = obj.publicProp*obj.privateProp;
end
end
methods (Access = private)
function privateMethod(obj,value)
obj.publicProp = obj.publicProp + value;
obj.privateProp = obj.privateProp + obj.doubleThisValue(value);
end
end
methods(Static)
function res = doubleThisValue(val)
res = 2 * val;
if coin == 'q'
value = 25;
elseif coin == 'd'
value = 10;
elseif coin == 'n'
value = 5;
elseif coin == 'p'
value = 1;
else
value = 0;
end
function total = insert_coins
total = 0;
