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.

The following units of conversions is used in this program

1 quarter = $0.25

1 dime = $0.10

1 nickel = $0.05

1 penny = $0.01

$1 = 100 cents

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

Suppose a computer has 16-bit instructions. The instruction set consists of 32 different operations. All instructions have an op

Kazeer [188]

Answer:

2^7= 128

Explanation:

An instruction format characterizes the diverse part of a guidance. The fundamental segments of an instruction are opcode and operands. Here are the various terms identified with guidance design: Instruction set size tells the absolute number of guidelines characterized in the processor. Opcode size is the quantity of bits involved by the opcode which is determined by taking log of guidance set size. Operand size is the quantity of bits involved by the operand. Guidance size is determined as total of bits involved by opcode and operands.

True; you have treat others the way you want to be treated. It is the golden rule for meeting anyone, whether it's online or in real life. If you were being mean to someone online, would you want someone to be mean to you the same way you were mean to that person? So, the answer is true.
