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.

function value = get_coin_value(coin)

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

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

THIS IS THE CODE SO FAR FOR THE PARTS BEFORE THE ONE I NEED HELP WITH

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

THIS IS THE CODE I NEED HELP WITH GETTING TO WORK

function [quarters, dimes, nickels, pennies] = get_change(total)

%your code here

cost = 115;

total = insert_coins;

change = total - cost;

while change >= 25

   quarters = 'q' + 1;

   change = change - 25;

end

while change >= 10

   dimes = 'd' + 1;

   change = change - 10;

end

while change >= 5

   nickels = 'n' + 1;

   change = change - 5;

end

while change >= 1

   pennies = 'p' + 1;

   change = change - 1;

end

disp('Total change: ' + (total - cost))

disp('Quarters: ' + quarters)

disp('Dimes: ' + dimes)

disp('Nickels: ' + nickels)

disp('Pennies: ' + pennies)

end

ANSWER:

I have provided the properly commented code in both text and image format so you can easily copy the code as well as check for correct indentation.
I have provided the output image of the code so you can easily cross-check for the correct output of the code.
Have a nice and healthy day!!

CODE TEXT (function get_change)

function [quarters, dimes, nickels, pennies] = get_change(total,cost)
    %your code here
    change = total - cost;
    % defining quarters, dimes , nickels and pennies counter
    quarters = 0; dimes= 0; nickels = 0; pennies = 0;
    while change >= 25
        quarters = quarters + 1;
        change = change - 25;
    end
    
    while change >= 10
        dimes = dimes + 1;
        change = change - 10;
    end
    
    while change >= 5
        nickels = nickels + 1;
        change = change - 5;
    end
    
    while change >= 1
        pennies = pennies + 1;
        change = change - 1;
    end
    
    fprintf('Total change: %d\n',(total - cost));
    fprintf('Quarters: %d\n',quarters);
    fprintf('Dimes: %d\n',dimes);
    fprintf('Nickels: %d\n',nickels);
    fprintf('Pennies: %d\n',pennies);
