The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimes Your program must define and call the following function. The function exact_change() should return num_dollars, num_quarters, num_dimes, num_nickels, and num_pennies. def exact_change(user_total) Use Python, please.In C++ Please Modify the program 8-31 from page 584, 585 by adding the following: 1. Add a prototype before main() like: void bubbleSort(Circle [], int); 2. On line 21 add the following function call: bubbleSort(circle, SIZE); 3. After main() function add the definition for bublleSort() function similar to the one on page 628. Evidently you must change the Inventory data type with Circle. The example in the textbook displays all the areas in order because the input is such that will cause the in order output. Your program should display all circles in order even when the input for radii is not in any particular order. // This program uses an array of objects. // The objects are instances of the Circle class. #include <iostream> #include <iomanip> #include "Circle.h" // Circle class declaration file using namespace std; const int NUM_CIRCLES = 4; int main() { Circle circle[NUM_CIRCLES]; // Define an array of Circle objects // Use a loop to initialize the radius of each…

Complete the program to read the needed values from input, that the existing output statement(s) can use to output a short story. Ex: If the input is: Eric Chipotle 12 cars the output is: Eric went to Chipotle to buy 12 different types of cars.1. Examine the following code segment.

Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('%0.2f' % your_value) Ex: If the input is: 20.0 3.1599 the output is: 1.58 7.90 63.20 Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with: 50 20.0 3.1599 the function returns: 7.89975 def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles. Note: This is a lab from a previous chapter that now requires the use of a function.3. Write a code for craps game. Craps is a dice game in which the players make wagers on the outcome of the roll, or a series of rolls, of a pair of dice.The rules of the dice game craps are as follows:You roll two dice. Each die has six faces, which contain one, two, three, four, five and six spots, respectively. After the dice have come to rest, the sum of the spots on the two upward faces is calculated. If the sum is 7 or 11 on the first throw, you win and play is over. If the sum is 2, 3 or 12 on the first throw you lose and play is over. If the sum is 4, 5, 6, 8, 9 or 10 on the first throw, that sum becomes your “point.” To win, you must continue rolling the dice until you “make your point” (i.e., roll that same point value). You lose by rolling a 7 before making your point. 4. Write a program which prompts the user for their age. If they are 19 or younger inform them that qualify for student discounts.
