To convert the inputs to dollars and cents, we make use of a combination of multiplication and addition.
The program written in Python where comments are used to explain each line is as follows:
<em />
<em>#This gets input for the number of quarters</em>
quarters = int(input("Quarters: "))
<em>#This gets input for the number of dimes</em>
dimes = int(input("Dimes: "))
<em>#This gets input for the number of nickels</em>
nickels= int(input("Nickels: "))
<em>#This gets input for the number of pennies</em>
pennies= int(input("Pennies: "))
<em>#This converts the amount to dollars and cents</em>
dollars = quarters * 0.25 + dimes * 0.10 + nickels * 0.05 + pennies * 0.01
<em>#This prints the amount to 2 decimal places</em>
print("Amount ${:.2f}".format(dollars))

Control data header at transport layer ensures correct delivery. It tracks the transmitted data and re-transmits in case of en error.
