9. using c++ Write a function daysInMonth that accepts an integer year, and an integer monthNum and returns the number of days in that month. Note that “30 days past September, April, June, and November”, etc. You need to include the year as you have to determine whether it is a leap year in order to decide whether to add 28 or 29 days for Feburary. MonthNum has a value of 1 to 12 with 1 as January and 12 as December. Note that you probably will need to call your isLeapYear function from a previous exercise to be able to write your daysInMonth function.
1. Develop a program for an automatic teller machine (ATM) designed to dispense money efficiently. The program should prompt the user to input a desired amount (which must be a multiple of 10 dollars), and the ATM should then determine the optimal combination of bills to dispense, including 100s, 50s, 20s, and 10s. You are required to write a function that calculates the quantity of each type of bill to be dispensed based on the user's input.The C program provided in this assignment accomplishes the following tasks: Finish the provided code according to the earlier explanation.#include <stdio.h>#include <stdlib.h>//prototypevoid dispense(int total,int *hundreds, int *fifty, int *twenty, int *ten);int main(){int userInput;int twenty = 0, ten = 0, fifty = 0, hundreds= 0;printf("ATM Bill Dispenser\n\nEnter an amount that is a multiple of 10 to bedispensed\n");do{printf("Enter desired amount: ");scanf(" %d", &userInput);//check that userInput is a multiple of…

Define a function named CoinFlip that returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls function CoinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0. Hint: Use the modulo operator (%) to limit the random integers to 0 and 1. Ex: If the random seed value is 2 and the input is: 3 the output is: Tails Heads Tails Note: For testing purposes, a pseudo-random number generator with a fixed seed value is used in the program. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used for each test case. The program must define and call the following function: string CoinFlip()

C++ Fix the broken code, Fix the function that is being used It does not charge the full hour for fractional portions. If you enter 4.5 it will return 27.50 as opposed to 30. Instructions to fix the code Consider this…. Charge will never be less than 20 so…… double charge = 20; for hours above 3…. If (hours >3) charge = 20 + ceil(hours -3)*5; where ceil brings it up to the next full hour value…. The charge will never be greater than 50 so….. If (charge > 50) charge = 50; now all you need to do is return charge Here is the code: #include<iostream>#include<iomanip>using namespace std;/* This is a function that calculates the charge of parking for the given amount of time (in hours) */double calculateCharges(double hours) {if (hours <= 3.0) { // If the time is less than 3 hours.return 20.0; // Charge a fixed amount of $20}else {double charge = 20.0 + (hours - 3.0) * 5; // Calculate the charge, which is $20 + ($5/hour for excess of 3 hours)if (charge >= 50.0) {…
