Vrite a program that determines the change given back to a customer in a self-service checkout machine of a supermarket for purchases of up to $20. The program generates a random number between 0.01 nd 20.00 and displays the number as the amount to be paid. The program then asks the user to enter ayment, which can be one $1 bill, one $5 bill, one $10 bill, or one $20 bill. If the payment is less than he amount to be paid, an error message is displayed. If the payment is sufficient, the program calculates he change and lists the bills and/or the coins that make up the change, which has to be composed of he least number each of bills and coins. For example, if the amount to be paid is $2.33 and a $10 bill is entered as payment, then the change is one $5 bill, two $1 bills, two quarters, one dime, one nickel, and wo pennies Execute the program three times

Please I want a python program for this using CSV write a function that takes a list of strings as inputs, and returns a single string created by joining all the input strings together, with a comma separating them. Now write another function that takes a list of lists of strings, applies the operation from question 1 to each list, and writes the result as a row of an output file. The function should return the path to the file where the strings were written. 3. Now, write the reverse of question 2: write a function that takes in a filename (which we will assume is a CSV), and returns a list of lists of strings, where one row in the file corresponds to one list in the output list (and each value between the commas in the file row is one element in the list).

Write a program in C Write two functions product1()andproduct2( )that can multiply two integers and return the result. Function product1()takes only two parameters (n1)and (n2)which are both input parameters. The second function product2( )takes an output parameter (p)in addition to those two input parameters.Write a program that opens a text file "integers.txt" to read two integers and calls the two functions product1( )and product2( )to test that they are working properly.

Objective is to track schedules for airplane flights. The flights go between cities. The aircraft type that is scheduled for that flight implies the seating capacity. We need to know the seating capacity so that we know how many seats we can sell. What would the airplanes, flights, and travel agency .cpp files be in c++? (part a,b,c)

Assume (or you can create it) a function for detecting prime numbers is created. Then, write a script file in MATLAB that will call that function for all number between 600 and 999, find the twin primes, safe primes, sexy primes, and Mersenne primes and "good" friends. Note: I already have the function (isprime(num)). I want the script file following the above conditions.
