skad [1K]
I think that the form of computing the project would be using is CLUSTER COMPUTING.

It involves a group of linked computers working together that it forms, in essence, a single computer. In this way, each user can work on his or her own tasks all at the same time. This will improve performance, increase output, and it is more cost-effective than using a single computer for the whole project.

Write a program that determines the value of the coins in a jar and prints the total in dollars and cents. Read integer values t
Shalnov [3]

Answer:

The programming language is not stated. To answer this question, I'll make use of python programming language.

<em>The following units of conversions is used in this program</em>

<em>1 quarter = $0.25</em>

<em>1 dime = $0.10</em>

<em>1 nickel = $0.05</em>

<em>1 penny = $0.01</em>

<em>$1 = 100 cents</em>

This program makes use of few comment (See explanation for line by line explanation)

Having listed the above, the program is as follows:

#prompt user for inputs

quarters = int(input("Number of Quarters: "))

dimes = int(input("Number of Dimes: "))

nickels = int(input("Number of Nickels: "))

pennies = int(input("Number of Pennies: "))

#Convert coins to dollars

dollar = 0.25 * quarters + 0.10 * dimes + 0.05 * nickels + 0.01 * pennies

print("Dollar Equivalent")

print(str(round(dollar,2))+" dollars")

cent = dollar * 100

print("Cent Equivalent")

print(str(round(cent,2))+" cents")

Explanation:

This first line is a comment

#prompt user for inputs

This line prompts user for value of quarters in the jar

quarters = int(input("Number of Quarters: "))

This line prompts user for value of dimes in the jar

dimes = int(input("Number of Dimes: "))

This line prompts user for value of nickels in the jar

nickels = int(input("Number of Nickels: "))

This line prompts user for value of pennies in the jar

pennies = int(input("Number of Pennies: "))

Using the coin conversion listed in the answer section, the user inputs is converted to dollars in the next line

dollar = 0.25 * quarters + 0.10 * dimes + 0.05 * nickels + 0.01 * pennies

The string "Dollar Equivalent" is printed using the next line

print("Dollar Equivalent")

This line prints the dollar equivalent of the converted coins

print(str(round(dollar,2))+" dollars")

Using the coin conversion listed in the answer section, the user inputs is converted to cents in the next line

cent = dollar * 100

The string "Cent Equivalent" is printed using the next line

print("Cent Equivalent")

This line prints the cent equivalent of the converted coins

print(str(round(cent,2))+" cents")

Please note that the dollar and cent equivalents are rounded to two decimal places. Even though, it's not a requirement of the program, it's a good programming practice
