Write a function that will help a vending machine return the most efficient change in coins possible when given a sales price and a payment. For example, if a sales price is $0.20 and a customer gives the machine a $1 bill, then your function should return $0.80 in change. More specifically, the function should return the $0.80 as 3 quarters and 1 nickel, because that's the most efficient (that is, it uses the fewest number of coins).
Here are the following types of U. S. coins that the vending machine can use for returning change:
Pennies: $0.01
Nickels: $0.05
Dimes: $0.10
Quarters: $0.25
Input Variable:
Your input variables will be an item price and a payment array with all of the monetary inputs into the machine that must be added together to compute the total payment. For example, the payment array which simulates the customer inputting a quarter, dime, and dollar for a total payment of $1.35 may look like:
[0] 0.25
[1] 0.10
[2] 1.00

Write a program that takes in 3 inputs [players (int type), expected game time (double type), team (char type)] and calculates actual game time (double) based on the following conditions: if the number of players or the expected game time is less than or equal to zero, it should output wrong input if the number of players is greater than 0 and less than or equal to 6 and if they are on the â€r’ or â€r’ team, their game time will be 10% faster. and if they are on the â€b’ or â€b’ team, their game time will be 15% faster. and if they are on the â€y’ or â€y’ team, their game time will be 20% faster. and if they are on any other team, they will play 0% faster. if the number of players is greater than 6 but less than or equal to 12 and if they are on the â€r’ or â€r’ team, their game time will be 20% faster. and if they are on the â€b’ or â€b’ team, their game time will be 25% faster. and if they are on the â€y’ or â€y’ team their game time will be 30% faster. and if they are on any other team, they will play 0% faster. if the number of players is greater than 12 but less than or equal to 18 and if they are on the â€r’ or â€r’ team, their game time will be 30% faster. and if they are on the â€b’ or â€b’ team, their game time will be 35% faster. and if they are on the â€y’ or â€y’ team, their game time will

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
